So as I'm essentially an amateur at serious photography, I have a few questions about film, development, and time. I'm looking for fine grain street photos with a pretty high contrast and a nice density. I've heard various things about pull processing and push processing Tri-X 400 film, so I'm a little confused. Also, I'm wondering if I should switch from TMax Dev to D-76, as I hear it yields better results. If I do switch to D-76 developer, what are the times for push processing/pull processing. As you can see, I'm very confused...please help.
