Profile notes
REFLX LAB 320D is built on Kodak Vision3 5207 250D motion picture stock featuring Kodak's newer AHU (Anti-Halation Undercoat) formulation, which replaces the traditional rem-jet layer with a gel-based undercoat that survives the C-41 bleach stage, controlling halation and improving scratch resistance without requiring ECN-2 processing. The AHU washes away cleanly during development, leaving no residue. REFLX LAB and community testers recommend a box speed of ISO 320 in C-41 for optimal density, slightly above the 250D baseline. The film delivers the classic Vision3 250D cinematic look: punchy daylight color, warm golden tones at sunset, and excellent highlight latitude. Contrast is higher than Kodak Portra 400 in daylight; sharpness slightly lower.
