I know I'm getting into some rough territory here as there are developers that fit the needs best of certain films and situations. However, I just wanted to ask the question to everyone - what is the best developer in your opinion? I hesitate to use the word "best", I think more of what I'm trying to say is "well rounded." I ask because I'm a student and the two developers that we have in the lab are D-76 and HC-110 dil B. Are these the most well rounded since it's the two that are supplied in our lab? I might be interested in buying and mixing my own developer just to experiment and therefore wanted everyones opinion. I've heard great things about Rodinal. Any thoughts or suggestions greatly appreciated! Thanks.
