Hello everybody! I recently started developing B&W films and I've got a question that is puzzling me. I have the data sheets for the films I use and they mention the agitation that I should do during development. For instance, 5 secs every 30 secs etc. On the other hand, the bottle of rodinal I bought (by A&O imaging IIRC) says something tragically different. So, what should I do? Follow the developer's instructions or do what the film manufacturer says? So far, I have only processed 2 films (TriX, Delta 100) and I followed the film manufacturer's instructions. The TriX was easy to print, but the Delta 100 seemed to have a bit too much contrast. And the second question is what changes when you use a different agitation method? Development rate? Is there a risk to get too "dense" negatives, even if you develop for the recommended time?
