Dark Ground
Dark Ground is a Fujifilm film simulation recipe for X-Trans V cameras. Every setting is published below in full, then how it was derived and why each control sits where it does.
The recipe
The Old Master portrait: a near-black warm ground, one soft key and no fill, umber and burnt sienna that stay readable instead of crushing, and skin that is luminous without being warm. Named for the dark underpainting a Dutch portrait is built on. Derivation in the notes.
Read from Suzanne Jongmans's Renaissance-style portraits, published by Colossal in August 2026 and made from recycled packaging material. One photographer, but four centuries of an unambiguous lighting tradition behind the frame.

Reala Ace finally wins one
This bank has rejected Reala Ace twice, both times on the same clause. North Light and Austurbane each needed to push hard against the highlight end, and the standing note here is that recipes on this base "shouldn't fight it with heavy Highlight softening", because the hard highlight end is half of what makes the simulation read true to life.
Nothing in a Old Master portrait fights the highlights. The brightest thing in frame is a collar or a cuff occupying two per cent of the picture, and it is supposed to stay a distinct bright rather than roll away into the surrounding dark. A hard highlight end is exactly what that wants.
Meanwhile the requirement that decides everything else is the shadow. The ground has to be dark enough to read as black at a glance and still hold the weave of the velvet when you look. Fujifilm describes Reala Ace's tonality as "deep, soft shadows and hard highlights", the inverse of most simulations, engineered to recreate era-accurate photographic prints while avoiding digital muddiness. Deep and soft in the same phrase is the entire problem, and no other base names it.
The third property closes it. Reala Ace applies nonlinear saturation compression, so the more saturated a subject is the more muted it renders. A restricted palette of umber, sienna and unbleached linen is what that produces without any help.
| Base | Why it lost |
|---|---|
| Nostalgic Neg. | The strongest rival, and Fujifilm even recommends it for "portraits in shadow" where "skin keeps richness in shade". It loses on control: the amber is fixed, stated not to move much under white balance, and a Old Master ground is sometimes umber and sometimes green-black. A locked cast takes that choice away. It is also carrying Revival House. |
| Pro Neg. Std | A single soft key is studio light, which is Fujifilm's own use case. But the base has no character to bring, and this look is almost entirely character. |
| Classic Chrome | Cool shadows and suppressed magenta. The ground would go grey-brown and the skin would go bloodless. |
| Pro Neg. Hi | Built to create shadows in flat light. There is no flat light here and no shortage of shadow. |
| Eterna | Cyan-shifted and flat at both ends. The opposite of a warm ground with a hard specular. |
| Velvia | Hard at both ends is right and the saturation is impossible. |
Shadow −1, which reads as backwards and is not
Every instinct says a dark, moody portrait wants Shadow at +2. That instinct produces a silhouette against a black rectangle, which is not what these paintings or these photographs do.
Look at what the reference actually holds: the velvet cape occupies more of the frame than the face does, and it has folds, nap direction and a change of tone across the shoulder. If the shadow end crushes, all of that becomes one shape and the picture loses its subject.
Reala Ace's shadows are already deep. What they also are is soft, and a negative Shadow value protects that softness rather than lifting the image. The darkness comes from the lighting, from having a single key and no fill, and from exposing down. It does not come from the tone curve, and asking the tone curve for it is what turns a Old Master reference into an underexposed photograph.
The same reasoning rules out DR400. Fujifilm's dynamic-range modes underexpose and then lift everything below the highlights, which is the one operation this look cannot survive. DR200 gives a stop for the lace and leaves the ground alone.
Highlight sits at 0, which is the bank's rule for this base stated plainly. There is no large bright area to protect and the small one should stay crisp.
Colour zero, for a reason specific to this base
Color at 0 on a look this restrained deserves an explanation, and it is a mechanical one rather than a taste one.
This bank's note on Reala Ace is that a Color adjustment behaves differently here than anywhere else: because the compression already tames whatever is most saturated, the Color control mostly moves low-saturation content. The lowest-saturation thing in a Old Master portrait is skin.
So a negative Color on this base would not mute the umber ground, which is protected by the compression. It would drain the face. The restricted palette has to come from the base and from what is in front of the camera, and Color has to stay out of it.
Color Chrome Effect Strong does the opposite job and is safe for the same reason. The ground is the one genuinely saturated region, it spans an enormous tonal range from lit fold to deep shadow, and the control exists to keep gradation in saturated reds and yellows rather than letting them block up. That is the velvet, described exactly.
Color Chrome FX Blue Off. There is no blue in the frame. The only cool note is a pale leaf, and deepening it would make it compete with the face.
The rest
- White Balance Daylight, +1 Red and −1 Blue. The ground is warm because the pigment is warm, not because the light is, so this is a light touch rather than a cast. The Red carries sienna, the Blue shift adds the yellow that separates umber from brick, and both stop at one notch because the white lace and the pale leaf are the only cool references in frame and a heavier shift turns them cream and khaki.
- Exposure −2/3 to −1/3, and this is the most important line in the table. The frame is mostly dark, so a reflective meter will try to make it middle grey and hand you a flat brown picture with a grey background. Everything else here fails if the exposure is not pulled down.
- Sharpness 0 and Clarity −1. Painted surfaces and skin. Clarity negative keeps the luminous quality that a single soft key produces and that micro-contrast destroys.
- Grain Weak, Small. Enough to stop a large area of near-black rendering as a digital gradient.
- ISO 250 to 3200. One window or one softbox with no fill is dimmer than it feels, but the look is clean and the ceiling stays low.
Variants
| Situation | Change |
|---|---|
| Green-black ground | WB 0 Red & 0 Blue, Color Chrome Effect Weak. The other half of the tradition, cooler and more Spanish than Dutch. |
| Candle or firelight | WB Incandescent, +1 Red, ISO 6400, EC −1. Real flame is the period-correct source and it is two stops down from a window. |
| Still life rather than a face | Clarity +1, Sharpness +1. Pewter, glass and fruit want the texture that skin does not. |
| Darker still | EC −1, Shadow −1.5. Approaching the point where only the face is lit. Watch the velvet. |
| Group or two figures | DR 400, Shadow 0. Two people at different distances from one key need range the single-figure version does not. |
| Deep blacks with no texture wanted | Shadow +1. Departs from the reference on purpose, toward modern studio portraiture. Fashion Editorial already lives there. |
Validation tier: Creative design, field-test pending. Grounded in Fujifilm's design statements for Reala Ace, in this bank's own notes on how the Color control behaves on that base, and in a reading of one published body of work rather than a catalogued aesthetic. No frames have been shot with it.
Test priority: in order
- A figure against a dark ground, one soft key, no fill, metered at −2/3. The whole recipe. Is the ground near-black with texture still in it, and is the face luminous rather than merely bright?
- The darkest large area at 100 per cent. The Shadow −1 test, and the recipe's central claim. If the velvet or the backdrop has crushed to flat black, the exposure is too low before the setting is wrong.
- A small white accent, a collar or a cuff. Confirms Highlight 0 keeps it distinct on a base with a hard top end, and that it is not clipping.
- Skin at Color 0. The base-specific test. If it reads drained, the compression is acting harder than expected and Color goes up rather than down, which is the opposite of what a muted look normally needs.
- The same setup metered normally. Worth doing once, because seeing the grey-backgrounded version is the fastest way to understand why the exposure line matters more than anything else in the table.
What would count as the recipe being wrong rather than needing a tweak: if the ground reads muddy brown rather than near-black at a correct exposure, then Reala Ace's shadows are not deep enough to carry this without help, and the rebuild is Pro Neg. Std with the depth taken from Shadow instead of from the base.
Pro tip: Expose down, then leave it alone. This is the one recipe in the bank that fails at correct exposure. A meter reads a mostly-dark frame as underexposed and tries to fix it, which turns a black ground into a grey one and a luminous face into a flat one. Start at −2/3 and let the histogram sit left.
Pro tip: Do not reach for Shadow +2. It is the obvious move for a moody portrait and it is wrong here. The reference holds fold, nap and tone change across a cape that fills half the frame, and a crushed shadow end deletes all of it. The darkness is a lighting decision, not a curve decision.
Pro tip: Color behaves backwards on this base. Reala Ace's compression already mutes whatever is most saturated, so the Color dial does most of its work on the least saturated content, which in a portrait is skin. A negative value here drains the face and leaves the ground exactly where it was.
Shoot JPEG. HEIF silently drops Clarity, which is carrying the luminous skin rendering.
Why it looks like this
Creative design (field-test pending). See the recipe and the Knowledge base.
Part 0: the source
Read from the design archive's look collection on 2026-08-25: Suzanne Jongmans's Renaissance-style portraits, published by Colossal in August 2026. The costumes are built from recycled packaging material, which is the work's subject and not its look.
One frame, and normally that would be too thin. It is enough here because the lighting tradition behind it is four centuries old, unambiguous and enormously documented, so a single well-made example is a sample from something already characterised rather than an isolated observation.
What the frame holds:
| Element | As rendered |
|---|---|
| Ground | Near-black, warm, with visible canvas or velvet texture inside the darkness |
| Key | One soft source, high and camera-left. No fill of any kind |
| Dominant colour | Deep umber and burnt sienna, occupying more frame than the face |
| Skin | Luminous, modelled, slightly desaturated. Freckles intact |
| Bright accent | White lace at collar and cuff. Small, distinct, not clipped |
| Cool note | A single pale green leaf. The only thing in frame that is not warm |
| Shadow behaviour | Deep enough to read black at a glance, readable when looked at |
Part 1: the requirements, ranked
- Dark that is not empty. The velvet occupies more of the frame than the face and it carries fold, nap direction and a tonal change across the shoulder. If the low end crushes, half the picture becomes one shape.
- Luminous skin. Modelled by a single soft key with no fill, which means a long gradient from lit cheek to unlit jaw, and any harshness in that gradient reads as a lighting error.
- A warm ground that stays a colour. Umber has to be umber across a huge tonal range, not brown in the light and black in the shade.
- One small bright that stays distinct. The lace is two per cent of the frame and it anchors the whole thing.
- A restricted palette. Everything not skin, ground or lace should sit down.
Requirement 1 is the hard one and it is the reason the base choice was not obvious.
Part 2: Reala Ace, on the third attempt
This bank has rejected Reala Ace twice and both times on the same clause. The standing note is that recipes on this base "shouldn't fight it with heavy Highlight softening", because the hard highlight end is half of what makes the simulation read true to life.
North Light lost it because a blown window is the interior photographer's failure mode and any interior recipe has to push the top end hard. Austurbane lost it because its largest frame area is whitespace that has to hold gradation, and because the compression would have flattened the one refracted spectrum that had to stay saturated.
Neither objection applies here, and that is the whole argument.
- Nothing fights the highlights. The brightest thing in frame is a collar occupying two per cent of the picture, and requirement 4 wants it to stay a distinct bright rather than roll away. A hard highlight end delivers that for free, so Highlight sits at 0 and the bank's rule is obeyed rather than broken.
- The compression is wanted. "The more saturated the subject, the more muted the color" is requirement 5 stated as a base behaviour. A restricted palette arrives without a setting.
- And the shadow clause, which is the one that decides it. Fujifilm describes Reala Ace's tonality as "deep, soft shadows and hard highlights", the inverse of most simulations, engineered to recreate era-accurate photographic prints while avoiding digital muddiness.
Deep and soft in one phrase is requirement 1 exactly. Deep gives a ground that reads black at a glance. Soft gives the gradation that keeps the velvet readable. No other simulation in the lineup names both, and it is unusual enough that Fujifilm calls it an inversion.
That a base rejected twice on one clause wins the moment the clause stops applying is worth recording, because it is the difference between a rule and a reflex.
The rejections
| Base | Why not |
|---|---|
| Nostalgic Neg. | The strongest rival. Fujifilm recommends it for "portraits in shadow" and says "skin keeps richness in shade", which is requirements 1 and 2 in one sentence. It loses on control: the amber is fixed and stated not to move much under white balance, while a Old Master ground is sometimes umber and sometimes green-black. It is also carrying Revival House, and two recipes from one batch on one base blurs both. |
| Pro Neg. Std | A single soft key is studio light, which is Fujifilm's stated use case, and its parameters apply straightforwardly. It brings no character to a look that is almost entirely character, and it would need the depth built from the tone curve, which Part 3 argues against. |
| Classic Chrome | Cool shadows are documented and wrong here. Suppressed magenta would take skin bloodless. |
| Pro Neg. Hi | Built to create shadows in flat light. There is no flat light and no shortage of shadow. |
| Eterna | Cyan and flat at both ends. |
| Velvia | Hard at both ends is right and everything about the saturation is wrong. |
Part 3: Shadow −1, which is the recipe's real claim
The instinctive setting for a dark moody portrait is Shadow +2. It produces a silhouette against a black rectangle, and it is worth understanding why that is a different picture rather than a stronger version of this one.
An Old Master portrait is not a picture of a lit face on a black background. It is a picture of a figure emerging from a ground, and the ground is a rendered surface with paint on it. The velvet cape in the reference holds more information than the face does. Crush the low end and the composition loses its largest element, and what remains reads as a modern studio portrait with a plain black backdrop behind it, which is a look this bank already covers with Fashion Editorial at Shadow +2.
Reala Ace's shadows are already deep. What a negative Shadow value buys is not brightness, it is protection of the softness half of "deep, soft shadows", so the gradation survives into the darkest part of the frame.
The darkness itself comes from three places, none of which is the tone curve: one key with no fill, a genuinely dark ground in front of the camera, and exposure compensation pulled down. Asking the tone curve to supply darkness that the lighting did not is what turns a reference like this into an underexposed photograph.
DR200 follows from the same logic. Fujifilm's dynamic-range modes underexpose and then lift everything below the highlights, which is the single operation this look cannot survive. One stop covers the lace. DR400 would raise the ground and undo the entire premise, which makes this one of the few recipes here where the higher setting is actively wrong rather than merely unnecessary.
Part 4: why Color stays at 0 on a deliberately restrained look
Color 0 on a look this restricted looks like an oversight. It is the opposite, and the reason is specific to this base.
This bank's note on Reala Ace is that the Color control behaves differently here than anywhere else: because the nonlinear compression has already tamed whatever is most saturated, a Color adjustment mostly moves low-saturation content. That is why fujifilm-negative reads natural rather than punchy at Color +2.
Run that backwards. The most saturated thing in this frame is the umber ground, which the compression is already holding. The least saturated thing is skin. So a negative Color here would leave the ground more or less where it was and drain the face, which is the one outcome requirement 2 cannot tolerate.
The restricted palette therefore has to come from the base and from what is in front of the camera. Color has to stay out of it. This is a good example of why a bank that records how each base behaves produces different settings from one that records how each base looks.
Color Chrome Effect Strong is the counterpart and it is safe for the same structural reason. The ground is the one genuinely saturated region, it spans an enormous tonal range from lit fold to deep shadow, and the control exists to keep gradation in saturated reds and yellows instead of letting them block up. Applied to velvet, that is the requirement written as a setting.
Part 5: where it sits in the bank
| Fashion Editorial | Dark Ground | |
|---|---|---|
| Base | Pro Neg. Hi | Reala Ace |
| Shadow | +2, deep blacks | −1, dark with texture |
| Dynamic Range | DR400 | DR200 |
| Question | How polished can a face look? | What is the figure emerging from? |
| Exposure | 0 to +1/3 | −2/3 to −1/3 |
It is the bank's second Reala Ace original after AP's Portra, and its first low-key portrait built around a ground rather than around a subject.
Part 6: honest limits
- No frames. Creative-design tier and nothing more.
- One image. The thinnest evidence base of any recipe in this batch. What carries it is that the lighting tradition is documented independently of this photographer, but the specific rendering here is one frame by one artist and the reading could be wrong about what is hers and what is the tradition's.
- Half of this is lighting and the recipe cannot supply it. One soft key, placed high and to the side, with no fill and a genuinely dark surface behind the subject. Every setting in the table assumes that light already exists. Shot under a normal room's ambient this recipe produces a slightly warm, slightly dark photograph and nothing more.
- The costume and the ground are production design. Jongmans builds hers. A recipe cannot hand anyone a velvet cape.
- The Color argument is inferred rather than measured. It follows from Fujifilm's statement about nonlinear compression and from this bank's reading of how that affects the Color control. Neither is a measurement, and the skin frame in the test list is the only thing that can confirm it.
- Exposure is doing more work than any setting. That is stated in three places in the recipe because it is the failure mode, and it means the recipe is less portable than most here: it depends on the operator overriding what the camera wants.
- No video version. Movie mode drops Clarity and both Chrome effects, and Color Chrome Effect Strong on the ground is central here.

Which cameras this fits
Built and measured on the X-T5. The X100VI, X-H2 and X-T50 carry the same 40.2 MP X-Trans CMOS 5 HR sensor, so this is not adapted for them. It is the same recipe. On an X-Trans IV body it needs one documented change: what the change is, why an older recipe looks wrong without it, and how to convert one yourself.
