Eight looks.
Colour and black & white.

Each look is a complete photographic treatment: a native Core Image foundation, Whistler colour grade, and baked-in grain. Specific film-stock matching will follow measured calibration, not marketing claims.

Swipe left or right on your image to cycle through looks. Swipe up to open the full filmstrip and compare at a glance.
