The Physics of Halation in Celluloid Emulsion

In traditional film photography, light striking the emulsion penetrates through the backing and reflects off the base. This physical bounce creates a distinctive warm chromatic aura around light sources — a phenomenon that digital sensors cannot replicate without deliberate optical color science.

Calibrating Dynamic Range for Fine Art Giclée Prints

A preset that looks dazzling on a mobile phone screen often collapses on an exhibition wall into choked shadows and brittle highlights. We build color profiles with print density curves designed for museum-grade pigment ink.
