The Film Factory Sampler is the entry point to Optics Lab originals: one 36-exposure roll each of Dnipro Pan, Genesee Blue, and Sakawa Pan.

Dnipro Pan is a slow, fine-grained panchromatic B&W negative based on Svema KN-2 — Soviet outdoor cinema emulsion sourced from Kyiv. Rate it at ISO 8; develop in total darkness.

Genesee Blue is based on Eastman 2366, Kodak's fine grain duplicating positive. Blue-sensitive only — skies go luminous, foliage darkens, reds fall away. ISO 6; handle under an OC safelight.

Sakawa Pan is based on Fujifilm 4771 HC Panchro Polyester — a discontinued high-contrast motion picture stock. Rate at ISO 25; meter at box speed and open +1 stop. Total darkness for loading and processing.

Three distinct looks from three continents of emulsion history. Each roll is bulk loaded to 135 and documented with its datasheet.
