Print-emulation pipeline

A print-emulation pipeline models the two-stage photochemical film system as an ordered, separable chain of nodes instead of one baked LUT. Stage one is the negative response — the camera stock’s status-M density curves, giving the toe-and-shoulder tonality. Stage two is the print — the negative projected through printer lights onto print stock (like Kodak 2383), adding the punchy contrast and color cross-over. Built as nodes, that becomes: a main tone curve (matched in grayscale), a tint stage (the per-channel color deviation), hue/sat shaping, and a white-point step. Because each stage is its own node, you can swap the “too contrasty” curve, retune the tint, or dial strength — everything a sealed film-emulation LUT won’t let you touch.
