Workflow:

Unlike standard image editors that use simple arithmetic inversion (255 minus pixel value), CyanHero uses logarithmic inversion to produce negatives where tonal steps correspond to real photographic exposure stops. Combined with process-specific curves calibrated for each alternative printing technique, this delivers negatives with proper shadow detail, smooth midtones, and controlled highlights — the difference between a muddy print and a stunning one.

CyanHero streamlines the digital negative workflow, letting you focus on the art of alternative process photography. Whether you're a seasoned practitioner or just discovering the magic of cyanotypes, CyanHero makes creating perfect negatives effortless.
