ILFOTEC DD will give pretty much normal film speeds. It is an all purpose developer for use in dip & dunk machines.(posted 8075 days ago)ILFOTEC DD-X is a similar developer, but because it is for one-shot use, it is a little more active. It will tend to give a slight increase in film speed, usually about 1/3 stop.
