Visual proofs — vocabulary-entry before/after gallery

Side-by-side renders of the synthetic ColorChecker chart and the synthetic grayscale ramp, before and after each vocabulary entry. For human visual validation: does each primitive visibly do what its description claims?

Renders use an empty-history baseline + --apply-custom-presets false so the chart passes through the darktable pipeline cleanly (input profile → output profile only, no scene-referred tone mapping). Each primitive is then applied in isolation — the only difference between baseline and per-entry renders is that primitive's effect. This lets you eyeball each primitive against the reference chart and verify it does what its description claims.

Production raw renders use the full _baseline_v1.xmp with sigmoid + colorbalancergb defaults — that path is correct for raws. The empty-baseline trick is specifically for chart-input isolation testing; it would not be appropriate for editing real photographs.

Masked columns: every non-mask-bound primitive renders additionally through a centered ellipse mask (radius=0.2, border=0.05) so you can see the spatial shaping in action. The mask covers the middle 16% of the frame; anything outside it should remain at baseline. This visually demonstrates that any primitive can be applied through a mask — see mask-applicable-controls.md for the per-module compatibility matrix.

Auto-generated. Regenerate via uv run python scripts/generate-visual-proofs.py after vocabulary changes. Commit the regenerated images alongside any vocabulary commit so the gallery and the manifest stay in sync.

Render size: 400x400, JPEG quality default. Inputs: synthetic targets from tests/fixtures/reference-targets/.

🚫 Real-raw fixture missing (#103). A small set of entries (currently HSL via colorequal) need a real raw for visual proof — the synthetic chart pipeline produces degenerate output. Those entries currently show a documented placeholder row; drop a fixture file at the path defined by REAL_RAW_FIXTURE in this script (see tests/fixtures/raws/README.md) to enable real-raw rendering.

NOTE: this entry's photographic effect requires lensfun identifier strings (camera/lens) and shooting metadata (focal/aperture/distance) to be populated. EXIF auto-binding for these is a follow-up; until then, the entry is most useful for overriding strength sliders on a darktable-GUI-authored baseline.

Axis names carry the denoise prefix to disambiguate from same-named axes on other modules (e.g. dehaze.strength). Per-channel noise calibration a[3]/b[3] auto-populated by darktable from camera+ISO database. WAVELETS mode would need an empirically-captured wavelet-curve baseline (tracked under #100 / task C); for now NLMEANS ships clean and lines up with Lightroom's patch-similarity Noise Reduction._

hsl_saturation

Parameterized HSL Saturation row (RFC-023). Lightroom HSL Color Mixer Saturation parity via darktable's colorequal module. 8 per-color axes (sat_red, sat_orange, sat_yellow, sat_green, sat_cyan, sat_blue, sat_lavender, sat_magenta); each range [-1.0, 1.0]; default 0.0. Negative desaturates that color zone (e.g. sat_orange=-0.3 → mute skin tones); positive boosts. Compose with hsl_hue and hsl_luminance for the full HSL Color Mixer.

🚫 Visual-proof rendering skipped. This entry's photographic effect requires real-raw input — its underlying darktable module produces degenerate output on the synthetic ColorChecker / grayscale fixtures (verified experimentally by varying the module's global tuning; chart pipeline doesn't recover). The byte-level apply path is verified by the 5-layer test coverage (per ADR-080). Visual proof on real raws is a v1.9.0+ work item — see _SKIP_VISUAL_PROOF_ENTRIES in the gallery script for the list and reasoning. To enable real-raw rendering, drop a fixture file at the path defined by REAL_RAW_FIXTURE (see tests/fixtures/raws/README.md).

hsl_hue

Parameterized HSL Hue row (RFC-023). Lightroom HSL Color Mixer Hue parity via colorequal. 8 per-color hue-shift axes (hue_red, hue_orange, hue_yellow, hue_green, hue_cyan, hue_blue, hue_lavender, hue_magenta); each range [-180.0, 180.0] degrees; default 0.0. Shifts that color zone toward an adjacent hue (e.g. hue_green=15.0 → foliage warmer toward yellow).

wb_kelvin_delta

WB Kelvin / tint UX wrapper (#102). Same temperature module as the temperature entry, but exposes photographic units instead of raw RGB coefficients. 2 axes: --param kelvin_delta=V (range [-3000, 3000]; positive = warmer) and --param tint_delta=V (range [-200, 200]; positive = magenta-shifted). Linear approximation: red_coeff = 1 + kelvin_delta * 0.0001, blue_coeff inverse, green_coeff = 1 + tint_delta * 0.0001. Daily-use accurate; not chromatic-adaptation-perfect. The temperature entry is preserved for users who want raw coefficient control. Note: kelvin_delta affects bytes 0 (red) AND 8 (blue); the manifest's field offset 0 is the primary-effect documentation; the decoder applies the inverse to blue automatically.

temperature

Parameterized white balance (RFC-021; first multi-parameter ship).

Range [0.5, 4.0] each; all default 1.0 (no shift). Replaces the v1.5.x discrete wb_cool_subtle entry. green_coeff added in #90 Bucket A.3 to close the Lightroom Tint parity gap. Starter's wb_warm_subtle remains as a discrete teaching artifact; production use of WB shifts should prefer this parameterized entry.

look_dark_pixels_global_lift 🟦 mask-bound

L2 look — lift dark pixels globally (no spatial mask). Pure parametric range_filter — luminance shadows. Useful when the intent is purely tonal: 'open up all the dark areas in the image, regardless of where they are.' Demonstrates the parametric-only path of RFC-024 / ADR-085.

ColorChecker	Grayscale ramp

skin_smooth_painterly 🟦 mask-bound

Approximate frequency separation for skin smoothing (Portrait Gap #4, cheap variant). Reduces local contrast (texture-band frequency) within the skin region — the color band stays untouched. Pass --value V or --param clarity_strength=V; range [-1.0, 4.0], typical -0.3 to -0.7 for natural smoothing. -0.5 default. Pre-baked with mask_skin_region. Not Photoshop's true frequency separation (band decomposition); approximation via bilat softening on a hue-masked region. Compose orthogonally with skin_uniformity (color-band uniformity) for the full skin-uniformity-plus-smoothing move. For sharper precision, override mask_spec via render_preview + LLM-vision (see docs/guides/llm-vision-for-masks.md Pattern 7).

-0.50	0.00	+0.50	+1.50	+2.50

skin_uniformity 🟦 mask-bound

Skin-tone uniformity (RFC-033). Compresses skin-band saturation variance toward uniform appearance — Capture One's Skin Tone Uniformity equivalent for chemigram. Pre-baked with mask_skin_region so the move is scoped automatically. Pass --value V or --param sat_orange=V; range [-1.0, 0.0]. -0.3 is moderate uniformity; -0.6 is strong (typical Woloszynowicz/Adler/Nordqvist range); -1.0 fully desaturates the skin band; 0.0 is no-op. Override mask_spec for per-image manual mask if mask_skin_region's hue-range fallback leaks (Phase-1 LLM-vision fallback per RFC-032). Frequency-separation texture work composes orthogonally; this primitive is color-band uniformity only.

look_portrait_natural_skin

Restraint-first portrait foundation — Tucker/Marino-aligned. Slight warm temperature (+0.03 red), exposure +0.1 EV, sigmoid contrast 1.2 (gentle s-curve), saturation_global -0.05 + vibrance +0.1 (mild chroma shaping that protects skin tones). The starting point for portrait work that doesn't push contrast or saturation as a stylistic choice.

ColorChecker (global)	Grayscale (global)	ColorChecker (centered ellipse mask)	Grayscale (centered ellipse mask)

look_portrait_editorial

Magazine / fashion editorial grade. Punchier sigmoid contrast (1.6), global saturation pull-back (-0.10) — counterintuitive but the move Adler/Woloszynowicz reach for; reduced overall sat lets the split-tone read. Cool-shadows + warm-highlights split (hue_shadows=210, hue_highlights=45). Compose with skin_uniformity if skin patches fight the grade.

ColorChecker (global)	Grayscale (global)	ColorChecker (centered ellipse mask)	Grayscale (centered ellipse mask)

look_portrait_skin_warm_lift 🟦 mask-bound

Subject-region warm + brighten. Slight warm temperature (+0.04 red) + exposure +0.2 EV. Pre-baked with mask_skin_region so the lift scopes to skin without affecting clothing or background. Pairs with skin_uniformity for a complete portrait skin pass.

ColorChecker	Grayscale ramp

look_portrait_background_dim 🟦 mask-bound

Dim and de-saturate the background to push the subject forward. Exposure -0.4 EV + saturation_global -0.15. Pre-baked with mask_subject + invert: true (RFC-034) — the photographer doesn't have to construct an inverse-subject mask manually. The parametric fallback for mask_subject is coarse (midtone luminance + center-bias); for clean subject vs. background separation override the mask_spec at apply time with a manually-drawn inverted ellipse, or escalate via render_preview + LLM-vision construction (llm-vision-for-masks.md Pattern 7) for a path-form subject mask.

ColorChecker	Grayscale ramp

look_portrait_split_tone_moody

Cinematic split-tone portrait — cool blue shadows (hue 210, sat 0.30) + warm orange highlights (hue 45, sat 0.20), sigmoid contrast 1.4. Stronger split than look_portrait_editorial; some photographers (Adler) consider this 'fashion-only' rather than a general portrait move. Borderline survey candidate — ships, but exercise judgment.

look_landscape_grand_vista

Heaton/PureRAW-style grand vista. Sigmoid contrast 1.4, mildly warm shadows (hue 30, sat 0.10), vibrance +0.10, bilat clarity_strength 0.5. The chemigram shape of LR's adaptive sky + foreground lift workflow rendered globally; for sky-specific work compose with look_landscape_sky_enhance instead.

ColorChecker (global)	Grayscale (global)	ColorChecker (centered ellipse mask)	Grayscale (centered ellipse mask)

look_landscape_intimate_quiet

Marino-style intimate / small-scene restraint. Very gentle sigmoid contrast (1.05), saturation pulled back (-0.10), bilat softened (clarity_strength -0.3 — opposite of clarity boost). The defining stylistic choice for forest interiors, abstract details, and any scene where drama would betray the subject. Applies LESS than the baseline does, deliberately.

look_landscape_golden_hour

Sunset / sunrise mood. Warm temperature shift (+0.07 red), sigmoid contrast 1.3, warm shadows (hue 30, sat 0.20) + amber highlights (hue 50, sat 0.15), vibrance +0.10. Pushes the warmth that golden-hour light almost has and amplifies it without breaking color credibility. For scenes already on the warm side, apply at lower strength via opacity — not authored as parametric (look-not-primitive).

look_landscape_blue_hour_cool

Twilight / pre-dawn / blue-hour mood. Cool temperature shift (+0.07 blue), sigmoid contrast 1.3, cool shadows (hue 210, sat 0.20) + neutral-cool highlights (hue 200, sat 0.10), saturation_global -0.05. Opposite mood from golden_hour; equally valid genre signature. Composes with sigmoid_contrast for stronger drama if needed.

look_landscape_atmospheric_haze

Misty / hazy / fog-as-subject mood. Hazeremoval strength 0.5 (lift visibility while preserving the moody atmosphere), bilat clarity 0.3, warm shadows (hue 30, sat 0.10) + vibrance +0.05. The trick: lift JUST enough to read details, not enough to flatten the atmosphere. Strong hazeremoval values (>1.0) produce 'no atmosphere' results that defeat the intent — keep restrained.

look_landscape_dramatic_moody

Page/Adamus-style dramatic atmospheric. Sigmoid contrast 1.7 (strong), cool shadows (hue 210, sat 0.20) + warm highlights (hue 30, sat 0.15), bilat clarity_strength 0.6. The dramatic counterpart to intimate_quiet — for stormy skies, rugged terrain, and weather drama. Pair with mask_luminosity_brightest_quartile darkening for stormy-cloud emphasis.

look_landscape_autumn_pop

Autumn foliage / fall color. Slight warm temperature (+0.04 red), colorequal sat_orange +0.30 + sat_red +0.20 (lift autumn colors) + sat_blue -0.10 (compensating to keep skies natural — without this, skies turn cartoonish). Bilat clarity_strength 0.4 for foliage definition. A targeted seasonal grade; not for non-foliage scenes.

look_landscape_sky_enhance 🟦 mask-bound

Sky-targeted enhancement (Heaton 'adaptive sky' shape). Cool-tone highlights shift (hue 200, sat 0.15) + slight vibrance (+0.05). Pre-baked with mask_sky (RFC-032) so the move scopes to the sky region automatically. Compose, don't replace — this is a focused enhancement to stack on top of any landscape look. For complex skies (sunsets, partial clouds, trees protruding into sky), override mask_spec with a constructed path mask via render_preview + LLM-vision (llm-vision-for-masks.md Pattern 7).

look_landscape_water_silk 🟦 mask-bound

Water surfaces — silky water in long-exposure work, glassy lakes. Bilat clarity_strength -0.4 (smooths the texture, OPPOSITE of clarity), cool-tone shadows (hue 200, sat 0.10), vibrance +0.05. Pre-baked with mask_water_blue_cyan so the smoothing scopes to water without affecting rocks, foliage, or sky. Reduces clarity selectively to enhance the smoothness photographers spent shutter-time creating.

bw_convert

B&W conversion (RFC-033 follow-up; survey Gap #1). Single colorequal plugin with all 8 sat axes set to -1.0 (full saturation kill = grayscale). Exposes 8 bright_X parameters emulating Adams-school color-filter strength: bright_red +0.3 lightens skin / red flowers / darkens skies in B&W; bright_blue -0.2 darkens skies; bright_green +0.3 lightens foliage; etc. The chemigram analog of Photoshop Channel Mixer (Monochrome) and Silver Efex Color Filters. Universal Step 1 of any B&W workflow per the photographer survey (6/6 photographers reach for color-filter-driven conversion as their foundational B&W move).

look_bw_classic_neutral

Classic B&W foundation — neutral channel weighting (no filter), mid contrast (sigmoid 1.3), mild structure (clarity 0.3). The starting point for any B&W work; compose with split-tone or chiaroscuro variants for stylistic direction. Per RFC-033 / survey Gap #1.

ColorChecker (global)	Grayscale (global)	ColorChecker (centered ellipse mask)	Grayscale (centered ellipse mask)

look_bw_high_contrast_chiaroscuro

Tucker/Thompson-style chiaroscuro B&W — strong sigmoid contrast (1.7), deep shadow brilliance (-0.20), lifted highlight brilliance (+0.10). For street/portrait B&W where dramatic light-shadow interplay defines the image. Compose with mask_subject for directional facial sculpting (Tucker portrait discipline).

look_bw_landscape_dramatic

Page/Adamus dramatic B&W landscape — red-filter-emulated conversion (bright_red +0.20 lightens land; bright_blue -0.30 darkens skies — the classic Adams-school red filter for storm-cloud drama). Sigmoid contrast 1.6 + clarity 0.5. For stormy skies, rugged terrain, weather drama. The B&W counterpart of look_landscape_dramatic_moody.

look_bw_split_tone_warm_shadows

Subtle warm-shadows toned B&W — sepia / selenium print evocation. Neutral B&W conversion + mid-strong sigmoid contrast (1.35) + warm-tone shadows (hue 30, sat 0.05) + cool-tone highlights (hue 210, sat 0.03). The split-tone tinting reads as 'toned print' rather than pure neutral B&W.

look_bw_silver_efex_zone_balanced

Whalley/Boutwell zone-system-aware balanced B&W — the restraint discipline applied to monochrome. Neutral conversion + gentle sigmoid contrast (1.15) + subtle clarity (0.15). The defining stylistic position for B&W work that doesn't push contrast or structure as a dramatic move; reads as 'measured tonal development' (Adams-school).

Notes

• Inputs are sRGB PNGs, not raw files. darktable processes them through its non-raw path — input color profile applies, demosaic does not. Some primitives (e.g., raw-aware white-balance moves) behave differently from how they would on a real raw. The gallery is for visual response validation, not pipeline calibration; for raw-pipeline direction-of-change validation see the e2e suite in tests/e2e/.

• Mask-bound entries (gradient/ellipse/rectangle, marked 🟦 above) route through the drawn-mask apply path per ADR-076. The mask geometry encodes into the XMP's masks_history; you see the spatial shaping in the rendered chart.

• Out-of-gamut patches on the ColorChecker (notably patch #18 Cyan) clip to nearest in-gamut sRGB; that clipping is in the input, not the primitive. See reference-targets/README.md.
