FPP Sonic 25 is a cinema soundtrack film repurposed for photography — similar in spirit to Washi Z and King Film Mono 50, but in orthochromatic form. Orthochromatism gives reds a dramatic, dark rendering. The soundtrack code is visible on the images — a unique signature. The FPP doesn't disclose the exact emulsion.
