ILFORD Microphen Powder for 1 Liter

Manufacturer's Description:

ILFORD MICROPHEN is a versatile black and white powder film developer that effectively increases film speed while retaining the grain properties of fine grain developers.

While a half-stop increase can be achieved with most low-ISO films, MICROPHEN is particularly useful with faster films such as HP5 PLUS, DELTA 400 PROFESSIONAL and DELTA 3200 PROFESSIONAL, where it allows an effective increase in film speed while maintaining grain properties.
