I am plan to try some slow speed B&W films. I have the following list: 1. Ilford Pan F 50 2. EFKE 25 3. Rollei Pan 25 However, I am not sure what developer should I use for these films. I am also not sure about the development time for these film, cause there are so many versions online. I am looking for some recommendation for B&W developers and developing time for these film. By searching the Internet, Diafine looks like the easiest way to develop these films. Only need 3 mins in two develop bath. Anyone have good results using Diafine? Any other Suggestions? What about stop bath and fixer? Hope someone can give me some hints, and helps on this. Many Thanks in advanced.
