Cool White

The retro-futurist institutional interior: overhead fluorescent practicals, cream and mint and mustard, chrome and formica, everything evenly lit and nothing hidden. Named for the lamp designation that makes it. Derivation in the notes.

Derived from cinematographer Stuart Dryburgh's account of a 2024 series, reported by PetaPixel. The production designer built fluorescent fixtures into the underground set and Dryburgh lit it entirely from them, aiming for "a lighting style similar to that of a 1950s supermarket". The show's governing principle, set by its director, was that it be "clean and well-photographed" rather than treated, and it was shot on film.

Correct the light. The period is in the room, not in the cast

The obvious way to shoot a fluorescent interior is to leave the green in, and it is wrong here for a reason the DP stated. The director rejected his first round of research, which leaned "treated and gamey", in favour of an aesthetic he described as "clean and well-photographed". Leaving an uncorrected green cast on faces is the definition of treated.

So this recipe corrects the light properly and lets the production design carry the era. Cream walls, mint doors, mustard upholstery, chrome and formica, and the fixtures themselves visible in frame. Those say 1950s. A sickly cast says horror film, which is a different genre and one this bank already reaches through other recipes.

• Fluorescent 3 is the Cool White preset, which is the lamp a mid-century commercial interior actually used. Matching the preset to the lamp is the correction, not a style choice.
• The +1 Red and +1 Blue shift is a magenta nudge, because Fujifilm's white balance grid runs red against cyan and blue against yellow, so moving both positive together opposes green. One notch on each takes the residual off skin without tinting the room.
• Real fixtures vary and rooms mix lamp types. A Custom reading off a white wall is the precise route and the presets are the fast one.

Astia, because Fujifilm built it for exactly this room

Two published properties and one stated design target, all three matching.

• Fujifilm engineered Astia for uncontrolled and mixed colour-temperature situations, naming night scenes with varied sources as a design case. A set lit by dozens of built-in fluorescent fixtures with the fixtures themselves in shot is a mixed-source scene.
• "The transition from highlights to shadows is smooth, while saturation is maintained." Smooth both ways gives the even, low-contrast, nothing-hidden rendering that institutional light produces. Saturation maintained keeps mint reading as mint rather than as grey-green.
• Soft at both ends without paying for it in colour is unusual, and the alternative bases all pay somewhere.

This is the bank's fourth Astia recipe, after Pastel Dream, Clean Girl and Golden Hour Glow. All four are bright and none of them collides: candy pastel, white-white skin, honeyed warmth, and a fluorescent basement.

Even light, and a curve that keeps it even

An institutional interior is lit so that nothing is hidden. That is the opposite of most looks in this folder and it drives both tone values.

• Highlight −1.5, because the tube fixtures in frame are the brightest things by a margin and they should read as lit objects rather than as white blobs. Astia is already soft at the top and this bank's note is not to stack softening past about −1.5, so this is the documented ceiling and the value the subject needs.
• Shadow −1. This bank's own note on Astia is that its soft shadow tone is easy to forget and that recipes wanting real depth have to take it from Dynamic Range or Shadow. This recipe wants the opposite of depth, so it goes the other way and opens the low end further. Under a ceiling grid there is nowhere for a shadow to hide anyway.
• DR200. One stop for the fixtures. DR400 would lift a low end that is already lifted and start flattening the little modelling overhead light produces.

The rest

• Grain Weak and Large. The show was shot on film, and this bank uses Large where the reference is motion-picture rather than a 35mm still. Weak keeps it clean, which the brief demands.
• Sharpness −1 and Clarity −1. Film again, and soft overhead sources produce no crisp edges. Clarity negative also helps faces under a light that lands from directly above, which is the least flattering direction there is.
• Color 0. Astia maintains saturation and the palette is pastel to mid. Pushing up turns institutional into cartoon. Pulling down loses the mint and the mustard that are doing the period work.
• Color Chrome Effect Weak. There is little genuinely saturated colour to give gradation to, and Strong would put a richness into the room that "clean" rules out.
• Color Chrome FX Blue Off. No sky, and the pale institutional blues are low saturation. Nothing to deepen.
• Exposure +1/3. Bright fixtures in frame pull a meter down, and the look is bright.

Variants

Validation tier: Creative design, field-test pending. Grounded in the cinematographer's published account of the lighting brief, in Fujifilm's stated design target for Astia, and in this bank's Dynamic Range & Tone Curve, the contrast controls tone notes on that base's native curve. No frames have been shot with it.

Test priority: in order

1. A room under a fluorescent ceiling grid, with a fixture in frame. The whole recipe. Is the light corrected enough that skin looks healthy, and does the room still read as fluorescent rather than as daylight?
2. A face directly under a tube. The hardest case in the genre, and the reason for the magenta nudge. If it reads green, the shift goes to +2 and +2 before anything else moves.
3. A tube fixture at 100 per cent. Confirms Highlight −1.5 with DR200 keeps it a lit object rather than a blown shape.
4. Mint, cream and mustard together. The palette test. All three should read as themselves at Color 0. If they read grey the base is not holding saturation and Color goes to +1.
5. The same room on this and with the white balance left at Daylight. The clearest way to see what "clean and well-photographed" costs and what it buys, which is the argument this recipe is built on.

What would count as the recipe being wrong rather than needing a tweak: if corrected fluorescent reads as ordinary indoor light with no period in it at all, then the era was never in the light and the recipe is doing nothing a neutral base would not, which would make this a production-design problem rather than a camera one.

Pro tip: Correct the light, do not season it. The instinct with fluorescent is to leave the green because it looks like fluorescent. The reference explicitly rejected that, and the reason is that an uncorrected cast reads as a genre signal rather than as a period one. The era comes from cream walls, mint doors, chrome and the fixtures being visible. The camera's job is to render them cleanly.

Pro tip: Match the preset to the lamp, not to the mood. Fluorescent 3 is Cool White, which is what a mid-century commercial interior actually ran. Fluorescent 2 is Warm White for older domestic fittings. Getting this right does more for the look than any other setting, and a Custom reading off a white wall beats both when the room mixes lamp types.

Pro tip: Shadow goes negative here, which is backwards for a basement. This bank's own note on Astia is that its shadows are already soft and that depth has to be added deliberately. This look wants no depth: institutional light exists so that nothing is hidden, and opening the low end further is what makes a room read as lit rather than as photographed in the dark.

Shoot JPEG. HEIF silently drops Clarity, which is softening both the film rendering and the overhead light on faces.

Part 0: mining the seam, and what it actually yielded

Revival House came out of a PetaPixel piece in which a working cinematographer described his own brief, and that turned out to be the strongest evidence class in this bank's creative tier. PetaPixel runs those interviews as a recurring series, so the series was worked through deliberately on 2026-08-25.

Four further articles, fetched and read in full:

One in four. That is worth recording plainly because the seam was described in this session as worth mining deliberately, and the honest result is that three of the four pieces are about camera, composition and production method rather than about how the picture looks. A recipe cannot deliver centre-framing, an one-hour take, or a human placed next to a mountain for scale.

The rejections are not close calls. Fraser's piece contains no colour or tone content at all. Lewis's is a gear and workflow interview. Trojnar's has one lighting idea, a hard practical isolating a subject in a dim frame, and that is Dark Ground with a street lamp instead of a window.

Part 1: what the Fallout piece gives

Dryburgh describes a show built from three deliberately different location palettes under one governing principle.

The vault is the one built here, and the choice needs justifying because the other two are also describable.

The Wasteland palette is orange, parched and brown, which this bank already reaches from three directions: Clay Season for muted earth tones, Sun Bleached for sun-drenched warm ground, and Mumbai for warm saturated street. A fourth would be a variant wearing a new name.

The Brotherhood palette is cyan off neutral greys and whites, which is Cold Open with a different subject.

The vault is unserved. The bank's only fluorescent recipe at the time of writing was AP's Superia, built for Indian tube light and Indian skin, which is a different lamp, a different intent and a different base. And retro-institutional interiors are having a genuine moment beyond this one show, which makes the recipe worth more than the single set it was read from.

Part 2: the problem, which is that everyone gets fluorescent wrong in the same direction

Fluorescent lamps put a spike in the green part of the spectrum. Every photographer meets this, and the two standard responses are both wrong for this look.

The first is to correct it away completely, which produces a room that could be anywhere and loses the period.

The second, far more common in film and television, is to leave the green in because green reads as fluorescent, and fluorescent reads as institutional, and institutional reads as dread. That is the hospital corridor, the interrogation room, the office at 3am. It is a genre signal.

The reference explicitly declines the second option, and the DP says so in the article: the first round of visual research was rejected as "treated and gamey" in favour of "clean and well-photographed". A sickly green cast on a face is treated.

So the recipe corrects the light properly and puts the period somewhere else: in cream walls, mint doors, mustard upholstery, chrome, formica, and the fixtures themselves being visible in shot. That is production design doing its job while the camera stays out of the way, which is what "clean and well-photographed" means.

The white balance follows from that. Fluorescent 3 is the Cool White preset and Cool White is the lamp a mid-century commercial interior actually ran, so matching them is a correction rather than a decision. The +1 Red and +1 Blue shift is the second half: Fujifilm's white balance grid runs red against cyan and blue against yellow, with no green axis of its own, so moving both positive together produces a magenta nudge that opposes the residual green. One notch on each is enough to take it off skin without tinting the room.

Part 3: the base

Fujifilm's published account of Astia gives three things, and all three are load-bearing here.

1. The stated design target is mixed and uncontrolled light. Fujifilm names bright uncontrolled outdoor lighting and night scenes with varied colour temperature as what the simulation was engineered for. A set lit by dozens of built-in fluorescent fixtures, with the fixtures in shot and daylight nowhere, is a mixed-source scene.
2. "The transition from highlights to shadows is smooth, while saturation is maintained." Smooth at both ends produces the even, low-contrast, nothing-hidden rendering that overhead institutional light actually gives. Saturation maintained keeps a mint door reading as mint rather than as grey-green, which matters because the palette is carrying the period.
3. It does not pay for its softness in colour, which every other soft base does. Eterna is flat and suppresses saturation by design. Classic Chrome is soft at the top and the lowest-saturation simulation in the lineup.

The rejections

Four Astia recipes now sit in this folder. Pastel Dream is candy pastel, Clean Girl is white-white skin, Golden Hour Glow is honeyed warmth, and this is a fluorescent basement. All four are bright and none is the same picture, which is the same argument this bank already makes for two Velvia looks pointing opposite ways.

Part 4: a curve that keeps the light even

Most looks in this folder use the tone curve to build a mood. This one uses it to prevent one.

An institutional interior is lit so that nothing is hidden. That is the point of the lighting design: a supermarket, a hospital, a bunker and an open-plan office all light every square metre because the room's function requires it. A photograph of one that has drama in it is a photograph of a different room.

• Highlight −1.5 protects the fixtures, which are the brightest things in frame by a wide margin and should read as lit objects rather than as blown shapes. This bank's note on Astia is not to stack highlight softening past about −1.5 because the base is already soft there, so this is both the documented ceiling and the value the subject needs, which is a comfortable place to land.
• Shadow −1 goes the opposite way from instinct. This bank's own Astia note is that its soft shadow tone is easy to forget, and that recipes wanting genuine depth have to take it from Dynamic Range or from Shadow rather than expecting the base to supply it. This recipe wants no depth at all, so it takes the note and runs it backwards.
• DR200 rather than DR400. One stop covers the fixtures. Two would lift a low end that is already lifted twice over, by the base and by the curve, and start removing the little modelling that overhead light produces.

Part 5: where it sits in the bank

It is the bank's second fluorescent recipe and its first for institutional interiors, and it is the second look derived from a cinematographer's stated brief after Revival House.

Part 6: honest limits

• No frames. Creative-design tier and nothing more.
• One of three palettes. The article describes a show built from three deliberately different location looks, and this is one of them. Calling it the show's look would be wrong, and the recipe credits the lighting brief rather than the production.
• The white balance is the least certain value here. Fujifilm's fluorescent presets are approximations of lamp families, real lamps drift with age and vary by manufacturer, and rooms mix lamp types freely. The face-under-a-tube frame in the test list is what settles it, and a Custom reading is the precise route the presets stand in for.
• No green axis on the camera. The correction has to be made through the red-cyan and blue-yellow grid, so the magenta nudge is an indirect route to an anti-green shift and it moves other things slightly on the way.
• The reference was shot on film, on LED volume stages, with the DP noting how much harder the colour temperature match is that way. None of that is reproducible and only its consequences are approximated, by Grain and by the two negative micro-contrast values.
• The period may not be in the light at all. The recipe's argument is that correcting the light and letting the palette carry the era is the right move, and the honest counter is that it might leave nothing distinctive behind. That is the failure condition stated in the test list, and it is a real possibility rather than a formality.
• No video version, which is again slightly absurd for a look read from television. Movie mode drops Grain and Clarity.
