An FFGL effect that develops your clip as an integral instant print while you watch. A Take exposes the frame, metered the way a camera would, and the print comes up out of a dark green-grey opacifier, pale and blue-cyan at first, warming to full colour as the slower magenta and yellow dyes arrive, each layer first-order at its own rate. Temperature scales every rate by the Arrhenius law, and because the timing layer that stops development speeds up less than the dyes do, cold film stops short, pale and green, as the manufacturer describes, while hot film finishes warm. A short or uneven spread leaves undeveloped corners, expired paste doesn't reach as far, and a dirty roller repeats its mark at its circumference. Shaking it doesn't help.
This demo runs the plugin's shaders in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
