Reflx Lab 640T AHU 35mm Color Negative Film — 36 Exposures

Reflx Lab 640T AHU is an ISO 640 (C-41, as marked on the box) tungsten-balanced colour negative film for 35mm cameras. It is developed in standard C-41 colour chemistry, which is what most labs — including ours — run every day.

It can be developed either way, and the speed you shoot it at depends on which: ECN-2 500 / C-41 640. An anti-halation undercoat replaces the remjet layer, so no lab has to strip anything off it.

High-quality REFLX LAB 640T AHU Color Film – 36 exp delivers rich, cinematic tones with exceptional color accuracy and fine grain. Perfect for filmmakers, analog photographers, and creative pros seeking dynamic contrast and reliable performance in diverse lighting. A top choice for expressive, filmic imagery.
