I recently came into the possession of 2 rolls each of Delta 100 and FP4+. What's the difference, and what should I expect from each? The internets tell me that Delta films are T grain, and FP/HP are "traditional" grain. The only T grain film I've shot is TMax 100, which I loved (especially for portraits), but I still always default back to my favorite Tri-X.
I'm just gonna have fun with these films, as 2 each is not enough time to properly test them and come up with a perfect (to me) exposure and development scheme. Oh, I'll be developing in HC110, probably dilution H. I shot HP5+ once, and it came out great in HC110H for 10 min. Figure I'll start with that for both the Delta100 and the FP4+.
I did find HP5+ much more mid toney and less contrasty than Tri-X (in addition, I find TMax to be more midtoney as well, though not as midtoney as HP5+ and no less contrasty than Tri-X). Will the same hold true for these Ilford films?
Oh, final question, I shoot them both at 100, right? Even though the FP4+ is rated at 125? (why did they rate it at a 1/4 stop?)
