An affordable way to get started with 4x5 film processing.

Stearman Press set out to find an elegant and affordable solution for processing your own 4x5 film, launching the SP-445 Film Tank. After several prototypes and lots of experimenting, the SP-445 processing system is the easiest for processing 4x5 sheet film and uses the least amount of chemicals. It will process up to four sheets of 4x5 film in only 16 ounces of solution.

The SP-445 film tank can be loaded by simply sliding the 4x5 film onto the holders (in darkness). Then the holders are lined up and inserted into the tank and you are ready to develop your film in daylight.

Michael J. ★★★★★

The 500ml chemistry requirement is a game-changer for me—my usual drums need a liter and this cuts my developer costs in half. The two holders load easily enough once you get the hang of it, and the tank's compact size makes it perfect for my cramped darkroom setup.

Brian ★★★★★

Only needed 500 ml of chemistry for a full set of sheets, which cuts my developer costs way down compared to the big tanks I used before. The lid seals tight with a satisfying click and I haven't had a single leak in six runs.

Zoe ★★★★★

The two holders load smoothly and the tank's compact footprint saves chemistry without any leaks so far. I've run three batches and the consistent agitation gave me even negatives every time.
