Ilford Microphen Developer Powder 1 Litre Black & White Film

ILFORD MICROPHEN is a fine grain film developer which gives an effective increase in film speed. A speed increase of up to half a stop can be achieved with most films but with faster films such as HP5 Plus, Delta 400 Professional and Delta 3200 Professional it is more.Many developers that give an increase in film speed usually produce a corresponding increase in grain size, MICROPHEN is formulated to overcome this disadvantage, the low alkalinity of the developer reduces grain size and grain clumping. Therefore, MICROPHEN is said to have a high speed/grain ratio, i.e. it gives a speed increase while retaining much of the grain characteristics associated with fine grain developers.MICROPHEN is particularly useful when using extended development times to push process fast films such as HP5 Plus, Delta 400 Professional, Delta 3200 Professional and SFX200.Film developer powderFor developing black and white filmsMaintains the film's characteristic fine grainCan be used as a stock solution, 1 : 1 or 1:31000 ml
