A second black-and-white stock, so it gets its own baseFilter rather than
borrowing Acros': the PHOTO STYLE chips are keyed by baseFilter and the two
greys have to sit side by side.
The look is the B&W MIX plus a push at both ends. The mix rides the matrix — a
non-BT.709 row set (0.38/0.56/0.06, identical rows, sum 1.00) so a red roof
reads bright, a blue sky deep, and the separation is contrast before any curve.
The push rides FILM_TONE (shadow -0.32, highlight +0.26) so the ends move
without touching the midtones, and the midtone slope is SIM_CONTRAST_BIAS (4
contrast units). Every knob still opens at neutral: a sim is colour and tone
only.
Both B&W stocks being mono is now asked once, through isMonochromeBase, so the
colour-only stages (saturation, white balance, the R/B fine-tune) and the
chrome/hue-mixer gate can never half-apply to one of them.
Mirrors the web app's rail (c403dd0).
Rename LIGHT GLOW to HDF EFFECT and gate it behind PRO: LITE renders the
chip greyed out with a PRO tag and cannot open its slider; restoration of
older settings that carry hdf > 0 still blocks export in LITE.
Play/licence pass:
- drop unused permissions (ACTIVITY_RECOGNITION, READ_MEDIA_AUDIO/VIDEO,
SYSTEM_ALERT_WINDOW) and requestLegacyExternalStorage
- rename the Leica sims to LC STREETLIFE CLASSIC/VIVID, drop the brand from
comments; fix app name text, canvaskit copyright, LICENSE owner
- remove expo-image-picker and expo-sensors (no JS import), delete dead
exports (computeMatrixTint, cinemaSeasonName, base64 helpers,
formatCoordinate)
- versionCode 3 / versionName 1.2.1, drop the personal email from About
- add docs/privacy-policy.html for the Play listing
Size: R8 + shrinkResources + bundle compression + ABI trim, 161 MB -> 76 MB.
Both flavors build from one JS tree: `lite` hands out the free apk
(com.locphamtran.recipescamera), `pro` sells as-is (same id + .pro, label
"RecipesCam Pro"). Release is signed from android/keystore.properties, both
files gitignored - lose either and no later build can install over this one.
The tier reaches JS through src/provariant.ts, which tools/set-variant.mjs
rewrites before each build (`npm run apk:lite` / `apk:pro`); the gradle flavor
alone would ship a Pro apk that thinks it is Lite.
The dev scaffolding goes: the three src/dev probes and their App effects, the
EXPO_PUBLIC_CAPTURE_MODE [CAPTURE] timing log, and the -PdevtestSuffix
side-by-side install hook. 'balanced' stays the shipped capture mode, which is
what those probes measured on the 12S Ultra.
Looking at the picture: WB now converts kelvin through the Planckian locus into
a luma-normalised gain (unity at 5500K, symmetric tint) instead of the old
one-sided push; LEITZ STREETLIFE splits into CLASSIC and VIVID; selecting a
recipe loads every knob it carries over the defaults and stays editable, and
RESET hands the panel back to the sim's own values. The in-app library picker,
the ultra-wide native module and recipe share/import land here too.
CLARITY and LIGHT GLOW existed only on the camera worklet and the export
engine, so a photo opened from the library ignored both. They now run in all
three library preview branches (libPhoto), and the preview clips them to the
drawn image - the export engine always clipped its bloom to the canvas, the
preview drew it over the whole rect, so the bloom bled past the photo onto the
black letterbox and over the frame's mat.
Provia/Velvia/Astia/Classic Chrome/Classic Neg/Acros each get their own
primaries+cross-talk matrix measured against the pipeline, plus a split-tone
stage (shadow/highlight tint uniforms) for Classic Chrome's teal and Classic
Neg's green-cyan shadows vs warm highlights.
The highlight knee opened at 0.45, so dropping HIGHLIGHT pulled a mid-grey
down with the true highlights. It now opens at 0.65 (and the coefficient
drops 0.32 -> 0.22 to stay monotonic), so the slider leaves everything up to
a light grey untouched and still rolls the bright end off. Shadow is
untouched — its 0.00..0.55 knee was already right.
Switching between the library and the camera now drops the edits back to
the recipe's own values, no frame and no custom mark. A frame was picked
for the still it sat on and the mark was placed against that very photo, so
neither may follow the user across the switch (or into a live capture),
exactly like the sliders that were tuned on the photo in front of them.
Highlight/Shadow scaled R, G and B by one luma gain. That keeps the ratio
but crushes absolute chroma, so -SH turned a saturated blue into near-black
and -HL turned bright colours grey, and both sliders only bit at the very
ends of the range (knees 0.80..1.00 / 0.00..0.30) — they read as dead on
any photo without true whites or blacks.
The curve now moves the luma and carries the colour difference (rgb - luma)
along at clamp(gain, 0.55, 1.35), so hue survives darkening and lifting
instead of collapsing to black or white. Both knobs are pure additive luma
shifts with soft knees over the upper/lower half: the 0.50 midpoint moves
under 3%, and the curve stays monotonic (the old multiplicative form was
not — with hl=-1 a grey 0.73 came out darker than 0.80).
Kotlin applyTone port and the native bench probe gates follow.
Verified on device (4200x2800 probe: grey ramp + colour patches), library
export at ratio 4:3: -10 highlight leaves the darks alone and drops white
243->189 with the sky still blue; -10 shadow keeps blue as dark blue
(0,0,254)->(0,3,146), never black, ramp stays monotonic. Export keeps the
source 4200x2800 as well, so nothing is cropped.
- FX: new VIGNETTING 0-10 control (chip + slider). Darkens the four
corners of the photo with a radial gradient whose radius is the photo
diagonal/2, so the falloff stays circular on any aspect. Applied in
preview (camera overlay, polaroid/wall window, plain library) and in
exportEngine pass 6b, always on the picture, never on the mat.
- LIGHT: new VIBRANCE -10..+10 (chroma-masked saturation in the tone
shader: vivid pixels move least). Renamed the existing saturation
control chip from COLOR to SATURATION - same param, clearer label.
- Fix: <Shader> takes a RuntimeEffect, not a gradient SkShader; the
preview vignette threw "Object is not a HostObject" when it got one.
Use the declarative <RadialGradient> child on the Rect instead.
- Preview: drop the "AE/AF LOCKED - TAP TO UNLOCK" banner; the lock
reticle is now itself the unlock touch target.
