- Repository renamed
Lightroom-Presets→EmulsionPresets. The old name was the most generic string in the category, which made the project impossible for search engines and language models to treat as a distinct entity. GitHub redirects the old URLs. - README rewritten so the first 200 words answer the query directly, with question-shaped section headings and a comparison table against VSCO, Mastin Labs and RNI.
presets.json— machine-readable catalog of all 451 presets (name, category, treatment, file path, raw download URL, one-line description), generated fromPresets/bytest/build_catalog.py.llms.txtandllms-full.txt— short index and full prose catalog for LLM crawlers.CITATION.cff— citable metadata for teaching and research use.- GitHub Pages site served from
docs/with Jekyll:_config.yml, front matter,robots.txtexplicitly allowing AI crawlers, auto-generatedsitemap.xml, and JSON-LD (SoftwareApplication,ItemList,FAQPage) on the index page. docs/category tables regenerated fromPresets/— all 13 counts now match the filesystem (previously several pages under-reported by 4–12 presets).AGENTS.mdrules 16–17: the catalog is generated, so it must be rebuilt on every preset change, and new presets must have a display name matching the filename stem plus a real description.
- Stale per-category counts in
docs/color-negative.md,black-white.md,slide.md,creative.mdandgenre.md. - Repo-root relative links in
docs/now point at GitHub, so they resolve on the Pages site too.
- White balance mode now declared on all 78 temperature presets.
crs:WhiteBalance="Custom"added to 72 presets that setTemperature(22 of them alsoTint) without declaring the mode.WhiteBalanceis the enum that activates the Kelvin value — in XMP a bareTemperatureis at best an as-shot display value and at worst ignored entirely. Six presets (theUtility/WB *family) already declared it. Adding the enum is a no-op if Lightroom was already inferringCustom, and a fix if it wasn't; either way the intent is now explicit.- Distribution: Geographic 26, Creative 19, Mobile 14, Decade 9, Genre 2, Photographer 1, Seasonal 1. No film-stock preset (Color-Negative / Black-White / Slide) sets WB at all, consistent with house rule 4.
AGENTS.mdrule 4 now requiresWhiteBalance="Custom"wheneverTemperature/Tintis present.
- Reset presets now actually reset.
Full Resetwas leaving three whole panels untouched: the parametric curve (ParametricShadows/Darks/Lights/Highlightsand their split points), the Black & White mixer (all eightGrayMixer*channels), and Lens Corrections/Transform (LensProfileEnable,LensManualDistortionAmount,VignetteAmount,AutoLateralCA, defringe,PerspectiveUpright). A previous edit survived a "full" reset as a result.Reset HSLhad the same GrayMixer gap — Lightroom's Color Mixer panel stores HSL and the B&W mix separately.Reset Effects + Detailgained the Lens Corrections defaults its description already claimed. - Stale grain settings removed from 18 presets.
GrainSizeandGrainRoughnesswere present alongsideGrainAmount="0", so the values were dormant but would apply the moment a user raised Amount. The two reset presets keep them intentionally — there they are Lightroom's defaults (25 / 50).
crs:SupportsAmount="True"retained on all 451 presets. Earlier notes suggested this was meaningless for presets, but six genuine Lightroom exports supplied by users all carryTrue, so the existing value matches real Lightroom output and was left unchanged.- All 451 presets parse clean; attribute count on
Full Resetis now 108 by design — a reset must name every value it clears.
- Absolute Kelvin white balance across 54 presets.
crs:Temperaturehad been written as relative offsets (+300,-200); Camera Raw expects absolute Kelvin (5800,5200). Affected presets were rendering with the wrong white balance or falling back to As Shot.
- Canonical attribute ordering across all 451 presets — calibration block, then Basic panel, then HSL, then ColorGrade — matching the order Lightroom writes itself.
- Redundant default attributes stripped so presets carry only the values that actually change (Utility WB and exposure-variant presets are now minimal deltas).
- Release asset rebuilt:
lr-presets-all.xmp.zipnow contains all 451 presets (was 445).
- All 451 presets parse clean with a strict XML parser — zero errors, zero raw
&.
- Silent-failure attribute names corrected across 333 presets.
crs:GrainFrequencyrenamed to the real Lightroom attributecrs:GrainRoughness;crs:SharpnessRadius,crs:SharpnessDetail,crs:SharpnessEdgeMasking, andcrs:SharpnessMaskingrenamed tocrs:SharpenRadius,crs:SharpenDetail,crs:SharpenEdgeMasking. The invalid names were being ignored by Camera Raw, so grain roughness and sharpening detail/radius/masking had no effect. - Creative Group scattering — all 52 Creative presets normalized to
crs:Group="Creative"(previously spread over 6 groups on import). - Grain/detail conflicts — 23 bulk-generated presets had
GrainAmount > 0alongside positive Clarity/Texture/Dehaze; those attributes removed andSharpness="10"/LuminanceSmoothing="0"enforced. - Utility/WB Daylight tint corrected from
+10to0with Temperature5500.
STYLEGUIDE.mdupgraded to v2.2 with new Section XII: The Attribute Whitelist & Confirmed Render Rules (silent-failure aliases, structural verification commands, grain budget, global-vs-per-hue desaturation, tonal register check, over-engineering test).AGENTS.mdgained rules 13 (real attribute names) and 14 (global fading / tonal register).- Verification: all 451 presets parse clean, zero raw ampersands, zero grain presets missing

- STYLEGUIDE.md with architectural framework for XMP construction
- Grain protection rule (#9): Sharpness ≤ 10 + LuminanceSmoothing=0 for all grain presets, Clarity/Texture/Dehaze=0 on Tri-X 400 and T-Max 3200
- 45 presets with GrainAmount > 0 now have Sharpness=10 (previously defaulted to 40 or had aggressive values)
- AGENTS.md updated with rules #9, #10, #11
- Slide presets: Changed from cinematic fade curve to punchy S-curve (0,0/42,28/128,128/213,230/255,255), restored community Blacks2012 values, set ColorGradeBlending=75
- Catastrophic XML syntax bug: ColorGrade attributes were raw text outside
<rdf:Description>, causing Lightroom to abort parsing. Rebuilt all 48 XMPs with proper XML attribute placement.
- Creative + Slide presets: cinematic curve (0,20/64,55/128,128/192,196/255,235) with Blacks2012=0 to prevent double-tracking
- Color-Negative + B&W: neutral curve, preserve original Blacks2012
- All 48 files verified clean — zero duplicate or malformed attributes
- ColorGrade migration: SplitToning → 3-way ColorGrade wheels for 41/48 presets
- Per-category tone curves: cinematic for Creative, S-curve for Slide, neutral for Color-Negative+B&W

- Structural boilerplate to all 48 XMPs: ProcessVersion 15.4, Treatment, Look block (Camera Profile UUIDs), ToneCurvePV2012 neutral baselines, SupportsAmount=True
- Missing
<crs:Look>block was causing Lightroom to skip non-linear input color matrix — rendered flat/washed out - Missing
<crs:Name>child elements fixed to match preset display names crs:SupportsAmount="False"→"True"on all
- Community alignment sweep: All 48 presets rebuilt with ONLY community-validated attributes
- Non-consensus values and zero-valued HSL cruft stripped
- S-curve double-boost prevention (Saturation capped at +5 for S-curve presets)
- Blacks floored at -30 for broad display distribution
- 3 critical bugs: (1) Calibration panel removed from 8 presets (causes unpredictable color channel imbalance), (2) Vibrance within 5 points of Saturation (gap >10 creates selective-color effect), (3) Temperature/Tint removed from 15 presets (WB conflicts with HSL)
- Extreme HSL saturation capped at ±60 across all presets
- AGENTS.md with critical rules: no Calibration, |Vibrance−Sat|≤5, no Temperature/Tint unless defining, cap HSL at ±60, keep presets simple (8-15 attributes)
- STYLEGUIDE.md with architectural framework (commit later expanded)
- Render pipeline (
test/render.py): Python CLI for applying XMP presets to RAW/JPEG using rawpy + numpy + scikit-image - B&W detection via ConvertToGrayscale=True with GrayMixer support
