Metrochrome

Metrochrome is a darkroom in your pocket. Load a roll, expose it, develop it, and print from it — on film that is measured rather than imagined. EVERY EMULSION IS A MEASUREMENT Thirty-six colour and black-and-white stocks, each carrying its own spectral sensitivity, characteristic curve, dye density and grain structure, digitised from the manufacturers' published datasheets. Nothing here is a preset with a film's name on it. The same curves the renderer samples are the ones plotted on each film's datasheet page in the app — they cannot disagree, and that is the point. A NEGATIVE, THEN A PRINT Your photograph is exposed onto the emulsion, developed, and then printed: through a colour paper for a colour negative, or onto Ilford Multigrade for a silver one. Grain sits in the density domain where it belongs, scaled to the film size you chose — a 110 negative is coarser than a 4×5 because it…
