Chuck, I use minimal agitation as this slows things down a bit. It really helps when doing films like Efke 25, which reacts too quickly for me with the standard dilution, almost a violent development. Since I liked the results, I've started doing more with it and other films. Efke 100 gives good results with nice edges and a bit faster film speed. It seems that minimal agitation allows the film to develop fully and slowly. Perhaps not for everyone, as it does take more time in the soup, but as an amateur, there isn't a problem for me and longer development times. best, tim
