Ilford Perceptol Fine Grain Developer Powder 1 L camera accessory

Fine-Grain B&W Film Developer

Ilford Perceptol is a powder concentrate that mixes to one litre of working solution for black-and-white negative processing. It is formulated to deliver very fine grain while maintaining good shadow detail. The product suits photographers who mix their own chemistry and want consistent results from a single 1 L batch.

Darkroom Users Seeking Maximum Acutance

This developer targets analogue photographers who prioritise fine grain over maximum film speed. It is not intended for workers who need a liquid concentrate for instant dilution or for high-volume labs that require replenishable tank solutions. Photographers pushing film several stops beyond box speed should consider alternative formulations.

One-Litre Powder Yield

The package produces exactly one litre of developer from powder, a fixed volume that determines how many rolls or sheets can be processed before fresh chemistry is needed.
