Assignment: The Exhibition Print and Its Critique

Two prints and a page of writing. The first print is the one this whole part has been building towards: one negative, anchored, filtered, worked on locally, developed to a fixed time, washed, dried, flattened, spotted and mounted. The second is the same print made again from the printing map alone, without looking at the first. The page of writing judges both, by a method, in a fixed order, under a light whose level you measured and wrote down.

The pair is the point. A single good print proves that you can make a good print once. Two prints that agree prove that the map is an instruction rather than a souvenir, and the size and direction of their disagreement is the most useful measurement in this part.

The intention

Produce, in two sittings of about two hours:

1. One finished exhibition print, mounted, from a negative you have already read, anchored and interpreted on the four pages before this one.
2. One second copy, made from the map alone, on paper from the same box.
3. One written critique covering both, in three passes — technical, structural, intention — with the passes taken in that order and none of them skipped because the print is pleasing.

Nothing here introduces a new chemical, a new technique or a new number. Every operation belongs to a page you have already worked through, and this page links them rather than repeating them. What is new is the judgement, and judgement is the part of printing most often left to mood.

Learning objectives

By the end of this assignment you should be able to:

• Apply a fixed three-pass critique method to a print, in an order you can defend, and produce a written judgement whose every claim names the thing on the paper that supports it.
• Distinguish a fault from a preference, and say which of the two any given remark is.
• State the conditions a print was judged under — illuminance, the light’s colour, the surround, the distance — and explain why a judgement made without them cannot be compared with anybody else’s.
• Make a print a second time from a written map, measure the disagreement between the two copies in stops, and attribute it to the map, the paper or the session using the records rather than memory.
• Critique work that is not yours, from a set of reproductions you assembled and whose rights you recorded, before turning the method on your own.
• Receive a critique without defending, and separate what was said about the print from what was said about your taste.
• Say what you would change in the negative, not only in the print, and what that means for the next film.

Prerequisites

All four practical pages of this part, and their outputs. Reading the negative supplied the two sentences of intention and opened the map; the test-strip lab supplied the base exposure and the ring-around; the local-control lab supplied the interpretation and the notation the map is written in; and the finishing lab supplied the wash sequence, the residual-thiosulfate test, the flattening, the spotting and the mount. Session consistency supplies the tray discipline and the session log that this page’s second sitting depends on.

From further back: the dry-down figure you measured in Part XVIII, and the enlarger certificate from Part XVI.

Safety classification

Level A, on the criteria of the classification rubric, and it is the same Level A as every other practical page in this part: tray chemistry at working dilutions and room temperature, with gloves, eye protection, tongs and a wet side kept clear of a dry side. The one hot appliance is the dry-mounting press, if you use one, and the one blade is the mat cutter; both were introduced with their controls in the finishing lab and neither is used differently here.

What is not a hazard here, and why. Most of this session is looking at dry paper under a lamp and writing, and that half carries no chemical hazard at all, because the print in your hand is metallic silver in hardened gelatin with the undeveloped halide dissolved out and washed away. The caution that does apply during it is a conservation control rather than a safety one, and it points at the print rather than at you: the Library of Congress asks for freshly washed hands or clean lint-free cotton or inert plastic gloves such as nitrile, no contact with the image surface, and an auxiliary support under a print that has to be turned over. A fingerprint from the fourth hour of a critique session is the most avoidable defect in this part. The printing half of the session reinstates the full Level A controls of the pages it borrows from, and those pages remain the authority for them.

Estimated cost

Band ££, and almost all of it is capital that already exists by this page: the enlarger, the timer, the trays, the washer, the press or the cutting mat. What this session consumes is about eight sheets of paper, four litres of working solution and one mount. The dated figures live in the planner, and for this part they are mostly gaps.

Estimated consumables cost

Consumed	This session	Sourced price	Cost this session
Fibre-base paper, 8 × 10 in	8 sheets	£47.04 for 25 sheets to £150.28 for 100	£12.02 to £15.05

Hinging tissue and paste, or photo corners	2 hinges’ worth	None in the price file	—
Spotting dyes	a few drops	None in the price file	—

The rows carrying numbers total about £25 to £39, and that is a floor rather than a total: three of the ten rows have no sourced price, and all three — the board, the hinges and the dyes — are exactly the materials that make this an exhibition print rather than a work print. The part overview states the gap in the same terms src/data/prices.json uses for the ones it already names, and no honest figure belongs in those cells until a dated UK listing exists. Equipment is not in the table: a press is not consumed, and neither is a lux meter.

If you work this assignment on resin-coated paper instead — a legitimate choice, and the cheaper one — the paper row costs less: 8 sheets of 8 × 10 in variable-contrast RC is £7.69 to £10.72 at £33.50 for 25 to £96.18 for 100, which brings the session’s sourced subtotal down to about £21 to £34 and still leaves the same three rows empty.

Alternative route

This page needs a room that can be made dark for two sittings, and there is no substitute for that if you want two enlargements. But the assignment splits cleanly, and more of it survives without a darkroom than you would expect.

Everything after the fixer is daylight work. The wash, the drying, the flattening, the trimming, the spotting, the mounting and the whole critique — which is most of the four hours — happen in the light. ILFORD’s own beginner’s sheet makes the point about the room, not the water: print-making needs a room that can be blacked out, and no running water, because the washing stage takes place in daylight. Part XVI’s reversible blackout is enough, and a hired hour in a community or college darkroom is enough for the two exposures.

At contact size, the whole assignment works unchanged. Using Part XVI’s frame, a print the size of the negative can be anchored, filtered, developed, washed, finished, mounted, repeated from the map and critiqued by all three passes. Local moves are clumsy at that size and edge softness has almost no room to work in, so those rows of the map will be short; say so in the critique rather than pretending otherwise, since an honest note about what the format prevented is itself a technical observation.

With no darkroom at all, three of the four hours are still available and they are the three this page exists for. Assemble the set of other people’s reproductions, work the three passes on them in full, and write those critiques. Then take the best print you already own — from Part I’s photogram, from Part V’s hand-coated sheet, from anywhere — set up the judging station below, and critique it by the same method. The critique is a transferable skill and it is the part of this assignment that compounds; the two enlargements can wait for the hour you book. What genuinely cannot be done without a darkroom is the repeat-from-the-map test, since it needs two exposures separated in time, and that is worth booking a second hour for rather than faking.

Before anything: the light you will judge in

A print is not an object with a fixed appearance. It is a reflector, and what it looks like is a product of the paper and the light, so a judgement recorded without the light is not repeatable and cannot be compared with anybody else’s — including your own, next month.

!What the course can and cannot tell you about ISO 3664

There is an international standard for this. ISO 3664, Graphic technology and photography — Viewing conditions, is the document that specifies viewing conditions for images on reflective media. Its published abstract states that it applies to critical evaluation of and comparison between reflection prints and other objects or images, and — separately — to appraisal of tone reproduction and colourfulness at illumination levels similar to those for practical use, including routine inspection. That distinction between a critical comparison and a practical-use appraisal is itself worth having: the standard does not treat them as one job, and neither should you.

Two facts about its status matter, because the number is widely quoted from the wrong edition. The third edition, ISO 3664:2009, was published on 14 April 2009, confirmed on systematic review in 2015 and 2020, marked to be revised in 2021, and withdrawn on 11 July 2025. The current document is ISO 3664:2025, the fourth edition, published in July 2025, 29 pages, from ISO/TC 42. Anything you read that attributes a viewing figure to “ISO 3664” without an edition is now at least one revision out of date.

What this course does not have, and will not pretend to. Under the course owner’s ruling of 4 September 2026 the ISO standards are not purchased and no part of them is quoted; what was read here is the publicly readable catalogue record and nothing else. So this page states no illuminance, no illuminant, no surround reflectance and no tolerance from ISO 3664, because it has not read them. That item is reported as unverified rather than filled with a number found at second hand, and what would settle it is a copy of ISO 3664:2025 or a Tier 1 restatement that names the edition it is quoting.

What the course can source is the other end of the print’s life. The Library of Congress’s preservation guidance is explicit about display: permanent display of photographs is not recommended; damage from light is cumulative and depends on intensity, duration and wavelength; blue light from 400 to 500 nm and ultraviolet from 300 to 400 nm are especially damaging; light levels in exhibits should be kept as low as possible but high enough to allow for viewing, in the range of 30 to 100 lux; and ultraviolet should not exceed 75 microwatts per lumen.

Put those two things beside each other and the practical problem appears. A print is judged under a working light and hung at 30 to 100 lux, and the eye adapts to whichever it is given. Part XIII’s tone-reproduction page already owns the mechanism — a print is judged against itself rather than against the scene, and the same print reads darker against a white mount than against a black one — and this page simply applies it. The course’s own convention, and it is a convention rather than a measurement, is therefore: fix one judging station, record it, and look at every print in it; then look again at the display level before you call the print finished.

The judging station, recorded once and used for every print in the set

1. 1The lamp, named and written down — type and colour temperature; angled so no specular reflection reaches the eye
2. 2Illuminance at the print, in lux — meter face up where the print sits; a number, not an adjective
3. 3A neutral mid-grey surround, larger than the print — the same print reads darker on white and lighter on black
4. 4Viewing distance, held constant and recorded — take arm’s length and across the room; they show different faults
5. 5The display check, at 30 to 100 lux — the Library of Congress range for exhibits — the only sourced figure here

The course's own convention. No illuminance for critical appraisal is stated, because ISO 3664's values have not been read; what is fixed is that the station is constant and recorded, which is what makes two judgements comparable.

One more variable belongs here because it is easy to blame on the light and is not the light. The image colour of a warm-tone paper is set partly by the processing, and ILFORD say so directly: long fixing times affect the image colour, and short washing times — such as when a washing aid is used — give a cooler image colour than long ones, with at least 30 minutes recommended for the warmest result. So if your two copies differ in colour, the wash times on the session log are the first place to look, not the lamp. On a neutral paper the question is smaller by design: ILFORD describe MULTIGRADE FB CLASSIC as having a white base tint and a neutral image colour, and their graded ILFOBROM GALERIE FB as having a neutral image colour “in all viewing conditions” — a manufacturer’s claim about that material, not a general property of silver gelatin.

Sitting one — the exhibition print

Two hours, and none of it is new.

1. Re-read the two sentences you wrote before the first test strip. Do not start until you have.
2. Re-anchor. A short test strip through the negative’s clear rebate, as the test-strip lab specifies, on the box you are about to use. This costs one halved sheet and removes the most common cause of a disappointing final print, which is a base exposure carried over from a different box.
3. Print the map. Base exposure, filter or filters, and every local move as written, in the order the map gives. Do not improvise. If the map is wrong, note the correction on the map as a new version rather than remembering it.
4. Develop to the fixed time, at the fixed temperature, with the session’s agitation, as session consistency requires, and run the session log alongside.
5. Make three, not one. Sheet one to confirm the map, sheet two with the single change sheet one asks for, sheet three as the copy you will finish. Number them all and keep them all.
6. Finish it: wash by the sequence you wrote down, prove the wash with the residual-thiosulfate test, dry, flatten, trim, spot, mount and label, all as the finishing lab sets out.

📓Close the map before you leave the room

The map has to be complete before the second sitting, because the second sitting is a test of it and a map edited from memory in between is not the document that was tested. Fill in the base exposure in seconds and in stops from the anchor, the aperture, the magnification, the filter, the lamp’s warm-up state, the developer and its age, the time and temperature, every local move in the notation, the dry-down correction, the paper’s box code, and the version number of the sheet you chose. Then put it away.

Sitting two — the second copy, from the map alone

About two hours, most of which is the writing rather than the printing. At least a day after the first sitting, and three weeks is better. Make the print again from the map, on paper from the same box, without looking at the first copy until both are dry.

Then measure the disagreement rather than describing it. Lay the two prints side by side in the judging station and answer three questions in order:

Are the local relationships the same? Is the sky the same amount darker than the mid-tone in both; is the dodged face the same amount lighter. This is the question the map exists to answer, because the local moves are written as ratios and ratios travel.

Is there an overall density difference? If the relationships hold but one sheet is uniformly darker, that is a speed difference, not a map failure. Express it in stops by finding which ring-around cell each print sits nearest.

Does the session log explain it? Sheet count against capacity, developer age, bath temperature, the box code. Those four cover most half-stop discrepancies, and without the log all four stay open.

⁇What the second copy can be held to, and where the number comes from

Two questions have to be settled before the comparison means anything: whether the test is achievable within one paper batch at all, and what agreement the course is entitled to claim. Only one of them is sourceable, and the page says which.

On the batch: yes, and the assignment removes it as a variable by requiring one box. The two manufacturer statements in this corpus point in opposite directions and neither is a tolerance. ILFORD say of ILFOBROM GALERIE FB that its deep blacks, brilliant whites and neutral image colour “can be relied upon from print-to-print and batch-to-batch” — a general claim about a graded fibre paper. Foma say of FOMATONE MG Classic that selected emulsion batches suit the lith process and that “it is necessary to test each emulsion lot separately (especially the modification of the exposure and developing time)” — a warning about one demanding process on a warm-tone variable-contrast paper. No maker in this corpus publishes a batch-to-batch variation in stops for enlarging paper, so the course states none, and the requirement to use one box is what makes the test about the map instead.

On the tolerance: it is the course’s own, and it is derived rather than measured. The local-control lab already ruled that the moves should reproduce “to about the resolution your ladder had — a third of a stop, the unit the map’s increments were chosen in”, and this page uses that and does not invent a second figure. Stated in full, the claim is: on paper from one box, a complete map should return a second copy whose local relationships are indistinguishable in the judging station and whose overall density is within about a third of a stop — one ring-around cell — of the first. A third of a stop is chosen because the ring-around’s exposure axis is built in thirds and because that is about the smallest step most printers reliably see on a dry print; it is a claim about the resolution of the method, not a manufacturing tolerance, and it should not be quoted as one.

And the honest limit, which the session-consistency page states and this page repeats rather than softens: a map and a log cannot promise an identical print. What they promise is that the remaining difference is small, one-directional and diagnosable.

The critique method

Three passes, always in this order, and the order is the whole design.

The three passes, and why intention comes last

1. 1Technical — what is physically on the paper — only things you can point at; no preference is admitted at this stage
2. 2Structural — how the picture is organised — every claim about the eye names the tone or edge that steers it
3. 3Intention — does it do what you said it would — read the two sentences back; do not rewrite them to fit the print
4. 4Close with one change, as a number or a setting — an aspiration cannot be tested next session; a setting can

The course's own method, and the general form of the seven-question sequence Part VII gives for pinhole negatives. Intention is last because it is the pass a maker is least able to answer honestly before the evidence is on the table.

The technical pass

Only what can be pointed at. Work down the sheet in this order and write a line for each, even when the line says the item is fine.

Black point. Is there a tone on this print that is the paper’s maximum black, and is it in a place the picture wanted one? A print with no true black has no bottom to its scale and everything above reads soft, which is a fault. A print whose blacks are large and empty where the negative held shadow detail is a different fault with the opposite cause.

White point. Is there paper-base white anywhere, and should there be? A print with no clean white is muddy; a print whose highlight has blown to bare paper where the negative held texture has lost that texture permanently.

Separation in the areas that matter. Not everywhere — in the two or three areas that carry the picture. Two adjacent tones that the negative distinguishes and the print does not are a local contrast failure, and it is the one the filtration lesson exists to fix.

Sharpness, and where it fails. Distinguish a negative that is not sharp from an enlargement that is not focused from an easel or a carrier that moved. Grain crisp and detail soft means the negative; grain soft too means the enlargement.

Evenness. Hold the print at a glancing angle. A gradient across the sheet that you did not put there is the enlarger’s illumination or its alignment, and the enlarger certificate says which corners were already down. This is the technical item most often mistaken for an edge burn.

The edges. Did each edge get what the map says, and is any of it visible as a band rather than as a fall-off?

Spotting, dust and drying marks. White specks that were not spotted; spots built too dark, which read as holes; a drying mark from a squeegee edge; a fibre dried into the surface. All four are avoidable and all four are what a viewer’s eye finds first at close range.

Dry-down disappointment. Compare the finished dry print with what you thought you had in the tray. If the difference is larger than the correction you applied, your dry-down figure is wrong for this paper or this drying method — and that is a measurement to redo in Part XVIII, not something to compensate for by feel.

The structural pass

Now how the picture is organised, and every claim names the physical fact that produces it.

Where does the eye enter? Usually the lightest large area, or the highest local contrast, or a face. Say which, and say what on the print makes it so.

Where does it go next, and does it come back? A path that leaves the frame and does not return is usually a bright edge or a line running out of a corner.

What do the edges do? An edge that is lighter than its neighbour leaks; an edge burned into a visible band builds a wall. Both are structural, both are on the map, and both were decisions.

What competes with the subject? Name the competitor and its tone. “A white sign at the right edge, two stops lighter than the wall” is usable. “The background is distracting” is not.

Did the local moves help, or merely happen? Take the map row by row. For each move, say what it was for and whether the finished print shows it doing that. A move that cannot be defended in one clause is a candidate for deletion in the next version, and deleting a move is as legitimate a revision as adding one.

The intention pass

Read the two sentences you wrote before the first exposure. Do not read them earlier — the point of putting them last is that by now you have looked at the print carefully and cannot pretend not to have seen what is in it.

Then answer, in one sentence: does this print do that? Yes or no, before any qualification.

If yes, say which of the decisions on the map did the work, because that is the transferable part. If no, there are only three honest continuations, and they lead to different places: the print failed to execute an intention that was right, which is a printing problem; the intention was wrong for this negative, which is a reading problem and sends you back to the first page of this part; or the intention was vague enough that it cannot fail, which is a writing problem and is the most common of the three.

!Why intention is last here and first in Part VII

The pinhole portfolio review runs a seven-question sequence with intention first, and this page runs three passes with intention last. Both are the course’s own and the difference is deliberate.

There, the picture is evidence about a camera. The log’s intention is a yes-or-no gate that decides which pile a negative goes into before anything is diagnosed, and the six questions after it are diagnostic. Here, the print is the object under judgement, and the intention question is the one a maker is least able to answer honestly at the start: knowing what you meant makes you see it. Putting it after the physical evidence is a defence against that.

The two schemes are the same method at different scales, and the mapping is exact: Part VII’s optics, exposure, tone, time and execution questions are its technical pass, its composition question is its structural pass, and its intention question is this one. The glossary’s definition of a critique is the compressed form of both. The course has no single assessment-rubric page, which is why the relationship is spelled out here rather than cross-referenced to one.

Why one print cannot be judged alone

The eye is poor at absolute judgements and good at comparative ones. “Is this too dark?” is hard; “which of these two is nearer right?” is easy. Every part of the method above therefore assumes something to compare against, and there are three, in increasing order of usefulness.

The previous version. Sheets one, two and three from sitting one, dry, side by side, in the judging station. This is the comparison that tells you whether the change you made was an improvement, and it is the reason the local-control lab insisted on one change per print.

The ring-around. Nine prints from one negative at a third of a stop and half a grade either side of a base. It converts “too dark” into “about one cell dark”, which is a number you can act on. Made once per paper-and-developer pair, it is the single most useful object in the darkroom for exactly this purpose.

A print you admire, made by somebody else, physically present. Not a screen image. A reproduction in a book is a halftone of a print, and a screen is emissive rather than reflective; both change the thing being compared. If you can get to a gallery, a museum print room or an exhibition with the print you are working on in a folder, do it once — the comparison is uncomfortable and it recalibrates in a way nothing else does.

The language of critique

A critique is a description with a judgement attached, and it is worth something only when the description could be checked by somebody else looking at the same sheet.

Describe what is on the paper, not what you felt. “The sky is at maximum density from the horizon upwards, so the cloud structure the negative holds is not on the print” is checkable. “The sky is oppressive” is not. The first tells you to burn less or to burn through a softer filter; the second tells you nothing you can do on Tuesday.

Avoid the vocabulary of praise. Beautiful, powerful, striking, evocative, moody, timeless. Each of them can be attached to almost any print without becoming false, which is what makes them useless: a sentence that cannot be wrong carries no information. The test is the one Part VII gives for a portfolio statement — could this sentence appear unchanged about a completely different print? If it could, strike it.

Separate a fault from a preference, and label which you are giving. A fault is a departure from what the maker was trying to do, or a defect of execution that any maker would want removed: a drying mark, a leaking edge, a blown highlight where the negative held texture. A preference is a different intention: you would have printed it darker, or harder, or without the burn on the left. Both are worth saying. Presenting the second as the first is the most common failure of critique, and it is why the intention pass exists — it fixes the standard the print is being measured against before anybody starts measuring.

✕Four sentences that look like critique and are not

1. “It needs more contrast.” Which two tones are not separated, and where? Contrast is a local quantity in a print and a global one only by accident.
2. “The blacks are blocked up.” Blocked means detail was there and is not. Check the negative first: if there is nothing in the shadow, the print cannot show it and the sentence belongs to the negative, not to the print.
3. “I would have cropped it.” A preference stated as a fault. Legitimate as “my preference would be a tighter crop, and here is what it would cost you at the left edge”.
4. “It doesn’t work for me.” True and unfalsifiable. If it cannot be attached to something on the paper, it is a report about the speaker.

Practising on work that is not yours

Do this before you critique your own prints, in the same session. Applying the method to somebody else’s work is easier, faster and more honest, and half an hour of it makes the pass over your own print noticeably less forgiving.

The course supplies no reproductions and cannot. There is no image pipeline here and no photographs: every illustration in this course is a drawing made for it. So the set is one you assemble, and assembling it is part of the exercise — because deciding what you are allowed to use is a skill the image policy asks of the course and this page asks of you.

Where to get a set whose rights are clear. The Metropolitan Museum of Art’s Open Access initiative, introduced in February 2017, makes all images of public-domain artworks and basic data on all accessioned works available for unrestricted use under Creative Commons Zero, marked with an OA icon and reachable through an Open Access filter in the online collection. That is the least ambiguous starting point. The Library of Congress’s Prints and Photographs Division is the largest, and its rights position is more nuanced and better teaching: the division conveys what it knows through catalogue records and rights statements, using wordings such as “considered to be in the public domain” and “no known restrictions”, and it states plainly that in all cases it is the researcher’s obligation to determine and satisfy copyright or other use restrictions — with the further caution that its guidance addresses use in the United States and that use elsewhere is governed by the law of the country of use.

Record six fields for every item you use, before you write a word about it. Creator, title, date, institution, licence and source URL — the same six the course’s own image policy requires of any figure. For a Library of Congress item, the credit line they ask for is the model: the Library of Congress, the specific collection, and the image reproduction number, as in Wright Brothers collection, Prints & Photographs Division, Library of Congress, LC-ppmsca-04598.

!What a screen reproduction can and cannot be critiqued for

Be honest about what you are looking at. A digital reproduction of a print, viewed on a screen, is an emissive image of a reflective object, at an unknown size, through an unknown scan and an uncalibrated display.

The structural pass survives it almost intact: entry, path, edges, competition and organisation are properties of the picture rather than of the object.

The intention pass survives it partly, if the institution’s record tells you what the picture was for.

The technical pass largely does not. Black point, base white, surface, evenness, dry-down, spotting and drying marks are properties of a physical print and you are not holding one. Say so in the write-up rather than making claims the medium cannot support — which is itself the discipline this page is teaching.

Receiving a critique, and what separates it from an opinion

At some point somebody says something about your print. The difference between a critique and an opinion is not politeness, tone or expertise: a critique names the thing on the paper it is about, and an opinion does not. “The left edge is lighter than the rest and my eye keeps going there” is a critique from anyone, including a stranger who knows nothing about printing. “It’s a bit flat” from a famous printer is an opinion until they say which tones.

Three working rules, and they are the course’s recommendation rather than a finding:

Do not explain while it is being given. The explanation is about the making; the critique is about the object. A viewer will not have the negative or the map, and their reaction is data precisely because they do not.

Write it down before you respond. Especially the remarks you disagree with, which are the ones you will otherwise lose. Two people independently finding the same edge is worth more than one person’s detailed argument about it.

Then sort it, the same way you sorted your own. Which remarks were faults and which were preferences. Act on the faults. Consider the preferences against your two sentences, and where a preference contradicts a stated intention, the intention wins for this print — and goes on the list of things to reconsider for the next one.

✦Write your own critique before you show the print to anybody

The glossary entry for critique makes this a defining feature rather than a suggestion, and the reason is mechanical: the first remark another person makes is what you will remember, and it will overwrite the judgement you had not yet written down. Ten minutes and a page first, then show it.

The honest conclusion: what you would change in the negative

Close the critique with the section that most printers skip, because it is the one that improves the next film rather than this print.

Look back at the technical pass and ask which of its items the printing could never have fixed.

If you needed a much harder grade than the paper’s published table suggested for the negative’s density range, the negative is flatter than you developed for, and the change is in film development time, not in filtration. If you needed a much softer one, the reverse. Part XIII’s paper sensitometry owns the matching and Part IX owns the controlled way to change it.

If a shadow you dodged had no detail to reveal, the film was underexposed for that subject, and no printing decision recovers it. That is an exposure-index conclusion, and it belongs in the exposure log as a change to your working index rather than as a note about this print.

If a highlight blew to base white with texture in the negative, the burn was too heavy or given through too hard a filter — a printing fault. If the negative had no texture there either, the film was overexposed or overdeveloped, and that is a development conclusion.

If the sharpest thing on the print is the grain, the negative was not sharp, and the cause is in the camera work rather than anywhere in this part.

Write one sentence for each finding, and one instruction to yourself for the next roll, expressed as a setting: an exposure index, a development time, a filter, an aperture. Not “expose more carefully”.

📷Optional branch — should this print be toned?

The question belongs at the end of a critique because it changes both the permanence and the appearance of the object you have just judged, and it is not only an aesthetic choice.

ILFORD’s own data sheet for MULTIGRADE FB CLASSIC recommends that prints made for display are toned to protect them from the oxidising gases found in many environments, and names selenium as having little effect on the image colour of that paper, with sulphide toning and silver image stabilisers as other protection methods. That is a manufacturer’s permanence recommendation, not a matter of taste, and it sits alongside the Library of Congress’s advice that permanent display is not recommended at all and that exhibit light levels belong in the 30 to 100 lux range.

Part XX takes up the chemistry: what each toner actually does to the silver image, which ones convert it and which deposit on it, what each costs in image colour and tonal scale, and which formulations carry hazards this course will not put in a home darkroom. Nothing in this part tones anything. What this page asks for is a decision recorded on the map — toned or not, and why — so that when you reach Part XX the question is already framed by a print you know intimately.

What to submit

• The edited proof sheet and the marked-up work print, from the first page of this part.
• The printing map, complete, versioned, and closed before the second sitting.
• The finished exhibition print, washed by a stated sequence and proved, dried, flattened, spotted, mounted on board bought against a specification rather than an adjective, and labelled.
• The second copy, from the map alone, on paper from the same box.
• The exposure record and the session log for both sittings, including the judging station.
• The written critique of both prints, in three passes, with the technical pass naming only things that can be pointed at, the structural pass naming the tone or edge behind every claim about the eye, and the intention pass answering yes or no before it qualifies.
• The critiques of the outside set, six to ten items, each with its six rights fields recorded and a note of which passes the medium supported.
• The measured disagreement between the two copies, in stops, with its attribution to the map, the paper or the session and the log entry that supports the attribution.
• The negative conclusions: what you would change in the film, each as a setting for the next roll.
• The toning decision, recorded on the map with its reason.

Recap

• A fine print is judged by a method, in a fixed order, or it is judged by mood. Technical first, because it is the only pass made of things that can be pointed at; structural second; intention last, because it is the pass a maker is least able to answer honestly once they know what they meant.
• The judging conditions are part of the judgement. ISO 3664 is the standard that specifies them — the 2009 third edition was withdrawn on 11 July 2025 and ISO 3664:2025 replaced it — but this course has not read its normative text and states no value from it. What it does state is a convention: one recorded station, one measured illuminance, a neutral surround, a recorded distance, and a second look at the 30 to 100 lux the Library of Congress gives for exhibits.
• The second copy is the assessment. The map is an instruction if a stranger could follow it, and the test of that is you, three weeks later, on paper from the same box. The course claims agreement to about a third of a stop overall with the local relationships intact — its own figure, derived from the ring-around’s resolution, not a manufacturer’s tolerance, because no maker in this corpus publishes one.
• A fault is not a preference. A fault departs from the stated intention or is a defect any maker would remove; a preference is a different intention. Say which you are giving, and note that the intention pass is what makes the distinction possible at all.
• Critique somebody else’s work first, from a set whose rights you recorded — the Met’s CC0 Open Access material, or the Library of Congress with its explicit warning that determining the rights is the researcher’s obligation — and be honest that a screen reproduction supports the structural pass and not the technical one.
• Close with the negative, not the print. A grade you had to reach for, a shadow with nothing in it, a highlight with no texture on either sheet — each of those is an instruction for the next film, expressed as a setting.

Check your understanding

Question 1. Your critique of a print begins "the shadows are blocked up and the whole thing feels heavy". What is wrong with that sentence as the opening of a technical pass?

• Nothing — it names a tonal problem and gives an impression, which is what a critique is
• It mixes a claim that has not been checked against the negative with a word that cannot be attached to anything on the paper, so neither half can be acted on
• It should have started with the composition instead
• It is too short to be a critique

Show the answer and why

Answer: It mixes a claim that has not been checked against the negative with a word that cannot be attached to anything on the paper, so neither half can be acted on

"Blocked up" means detail existed and was lost, which is a claim about the negative as much as about the print — so it is checked with a loupe on the negative before it is written, and if the shadow holds nothing then the sentence belongs to the exposure record rather than to the print. "Feels heavy" is the other failure: it could be attached to almost any print without becoming false, which is precisely why it carries no information. The technical pass admits only things that can be pointed at, and the working replacement here is something like "the shadow under the arch is at maximum black across about a fifth of the frame, and the negative holds two distinguishable tones in it" — a sentence somebody else could check on the same sheet.

Question 2. Three weeks after the exhibition print, you make the second copy from the map on paper from the same box. Every local relationship is intact, but the whole sheet sits about one ring-around cell dark. What does the method tell you to conclude, and what do you check next?

• The map has failed and every local move must be re-measured
• The overall density is an absolute and the local moves are ratios, so the moves travelled and the base did not; the session log is checked for sheet count, developer age, bath temperature and box code before anything is changed
• The paper batch is faulty and should be returned to the supplier
• The dry-down correction must be doubled on the next print

Show the answer and why

Answer: The overall density is an absolute and the local moves are ratios, so the moves travelled and the base did not; the session log is checked for sheet count, developer age, bath temperature and box code before anything is changed

A uniform shift with the internal relationships preserved is the signature of a speed or a processing change rather than of a bad map, because the local moves are written as fractions of the base exposure and therefore survive a change in speed while the base, an absolute in seconds, does not. One ring-around cell is a third of a stop, which is the agreement the course claims for a complete map on one box — a figure derived from the resolution of the ladder the map was written in, not a manufacturer tolerance, since no maker in this corpus publishes a batch-to-batch variation in stops. The session log exists for exactly this fork: sheet count against capacity, developer age, bath temperature and box code account for most half-stop discrepancies, and without it all four stay open.

Question 3. Why does this page state no illuminance figure for judging a print, given that an international standard for viewing conditions exists?

• Because no standard covers reflection prints, only transparencies and monitors
• Because ISO 3664 covers exactly this, but the course does not purchase or quote the ISO standards, so it has read only the public catalogue record and reports the values as unverified rather than repeating a number found at second hand
• Because illuminance does not affect how a print looks
• Because the Library of Congress figure of 30 to 100 lux replaces it

Show the answer and why

Answer: Because ISO 3664 covers exactly this, but the course does not purchase or quote the ISO standards, so it has read only the public catalogue record and reports the values as unverified rather than repeating a number found at second hand

ISO 3664, Graphic technology and photography — Viewing conditions, is precisely the standard, and its published abstract confirms that it applies to critical evaluation and comparison of reflection prints and, separately, to appraisal at illumination levels similar to practical use. What the course has read is that catalogue record and nothing more, under the owner ruling of 4 September 2026 that the ISO standards are not bought and no part of them is quoted — so it can tell you the standard exists, that the 2009 third edition was withdrawn on 11 July 2025 and that ISO 3664:2025 supersedes it, but not what illuminance or surround it specifies. The Library of Congress range of 30 to 100 lux is a different quantity and does not substitute: it is a conservation limit for how brightly a print may be displayed, not a specification for how brightly it should be appraised.

Question 4. A visitor looking at your mounted print says "I would have printed the sky darker". You wrote, before the first exposure, that the sky should stay open so that the figure reads against it. What does the method say to do?

• Reprint with a darker sky, because a viewer’s reaction is the real test
• Record it as a preference rather than a fault, weigh it against the written intention, keep the intention for this print, and add the question to the list for the next one
• Dismiss it, because the visitor has not seen the negative
• Rewrite the intention so that the remark becomes a fault

Show the answer and why

Answer: Record it as a preference rather than a fault, weigh it against the written intention, keep the intention for this print, and add the question to the list for the next one

The remark names something on the paper and is therefore a legitimate critique rather than an opinion, but it proposes a different intention rather than identifying a departure from yours — which makes it a preference, and the two are recorded differently. The intention pass exists to fix the standard the print is measured against before anybody measures, so for this print the written intention wins; the preference goes on the list to reconsider for the next version, where it may well be right. The last option is the failure the method is designed to prevent: rewriting the two sentences to fit either the print or the audience empties the intention pass of any power to fail, and an intention that cannot fail is not an intention.

Question 5. You assemble a set of eight museum reproductions to practise the three passes on, viewed on a screen. Which pass is least supported by that medium, and why?

• The structural pass, because composition depends on the physical size of the print
• The technical pass, because black point, base white, surface, evenness, dry-down, spotting and drying marks are properties of a physical object seen by reflected light, and a screen is emissive, uncalibrated and at an unknown scale
• The intention pass, because the maker’s intention is never recorded
• All three are equally supported, since a good scan reproduces everything that matters

Show the answer and why

Answer: The technical pass, because black point, base white, surface, evenness, dry-down, spotting and drying marks are properties of a physical object seen by reflected light, and a screen is emissive, uncalibrated and at an unknown scale

The structural pass travels well, because entry, path, edges and competition are properties of the picture rather than of the object; the intention pass travels partly, when the institution’s catalogue record says what the picture was for. The technical pass is the one that does not travel, and the reason is physical rather than a matter of scan quality: a reflection print judged in a recorded light and an emissive image on an unknown display are not the same measurement, and the specific items in the technical list — the deepest black the paper can give, the base white, the surface, evenness across the sheet, dry-down, spotting and drying marks — exist only on the object. Saying so in the write-up is the point of the exercise, because knowing which claims your medium can support is the same discipline as knowing which numbers your sources can support.
