Ilford Microphen Developer Powder for Black & White Film (Makes 1L)

**ILFORD Microphen Fine Grain Film Developer**

**Overview**
ILFORD Microphen is a fine grain developer specifically designed to maximize film speed, making it ideal for films that can be push-processed. Optimized for higher exposure ranges, Microphen reduces grain size and prevents clumping due to its low alkalinity.

Unlike most high-speed developers that increase grain size along with film speed, Microphen delivers an impressive speed-to-grain ratio, achieving speed gains while maintaining fine-grain characteristics similar to those of standard developers. With many films, Microphen supports push-processing to speeds up to **EI 3200/36**, such as with **ILFORD HP5 Plus film**.
