Looking for Reflx Lab 640T AHU sample photos? These frames were shot on a Leica M3 with Reflx Lab 640T AHU — a tungsten-balanced 35mm color-negative film. The shop listing processes it in C-41 or ECN-2 (ISO 640 in C-41, ISO 500 in ECN-2). These portraits were developed in C-41.
AHU means anti-halation undercoat. Classic cinema film used remjet — a black carbon layer on the back of the roll that stops light bouncing through the base (that bounce is what makes glowing halos). Remjet has to be washed off, and it will ruin a normal C-41 tank if it isn’t. Kodak’s AHU layer does the anti-halo job inside the emulsion, so there’s no remjet to remove.
The original cinema stock is Kodak Vision3 500T AHU — tungsten Vision3, remjet-free. Reflx Lab 640T AHU is a stills/C-41-oriented take on that look: cinema tungsten color, 35mm stills packaging, no remjet step. In these daylight portraits, watch skin (fair tones stay believable), the tungsten-to-daylight shift (a cooler/neutral bias versus a daylight stock), and contrast on navy dots, plaid, and black vest. Highlights stay controlled because AHU is still doing anti-halation work — this is not the CineStill remjet-off bloom.
