If you can get hold of _The Film Developing Cookbook_ by Anchell and Troop; Focal Press, ISBN 0-240-80277-2) you will get a good idea about differences in developers. However, the best thing would be to go ahead and try them! Shoot the same sort of pictures, and process with each developer. Keep everything else as much the same as possible.(posted 8854 days ago)What format are you using? What type of film? It makes a difference in what you want a developer to do.
What _is_ your current development routine?
D-76, often at 1+1, has been the most popular developer for many years. ID11 is a D-76 version, only very slightly different because the two-envelope packaging allows them to leave a couple of preservatives (stabilizers?) out. HC110, particularly in dilution B, has a slightly different look; to me, it seems a little grainier, a little sharper and more contrasty- another classic look. I used Microdol-X quite a bit at one time; to me it is now too "mushy." I haven't used Sprint chemistry. I seems that it would be convenient, and it is supposed to be less smelly and toxic.
When you get your results and your own feelings on these developers, please post them back. You can have some fun with this!
