// Film simulations. These are the fixed "look" presets at the front of the
|
|
// PRESETS chip row, and each one is COLOUR AND TONE ONLY.
|
|
//
|
|
// A sim carries exactly two things: its `baseFilter` colour matrix
|
|
// (colorUtils.ts) and, where the stock needs to shape one end of the curve, its
|
|
// FILM_TONE entry (toneShader.ts). Everything the sim does to the picture is in
|
|
// those two places — including the brightness a stock owns: that is folded into
|
|
// the matrix through SIM_EXPOSURE_BIAS (colorUtils.ts), never into
|
|
// `adjustments`. `adjustments` is therefore the neutral default for every sim —
|
|
// no grain, no clarity, no saturation push, no exposure/highlight/shadow move —
|
|
// because those are the user's knobs, not the stock's. A sim is a clean starting
|
|
// point, never a baked recipe; any further look is added afterwards.
|
|
//
|
|
// Name → the stock's colour and tone it must stand for. This table is the
|
|
// REFERENCE ONLY: the string at the left is just the app's label for the chip
|
|
// (the legacy 'PES' spelling), and what matters is that the sim behind it grades
|
|
// the picture the way the stock at the right does. So a change to a label must
|
|
// never touch the grading, and a change to a grading never renames the chip:
