My wife, not a photographer, bought this film for me for my birthday (Ilford Pan F Plus 50, 35mm). She said she bought it because the reviews sounded good. It's nothing I would have chosen to shoot -- not yet. But I'm up for a challenge. I'm thinking I'll load it in my Yashica T5 (T4 Super) and take some headshots of my family and other loved ones. This is slow film, so I think these portraits will have to be outdoors. I know the T4/T5 is known to have a (relatively) bright flash (so Terry Richardson would make us believe). But is it bright enough to use indoors or in suboptimal lighting? Will the flash add anything indoors? What I don't have a good understanding of is how film speed and on-camera flash work together. I seem to remember reading that the T4/T5 flash is "optimized" for 400 speed film. Also, I have D76 on hand, but I have an itching to try developing it in Perceptol. I've read that Perceptol also works well with Neopan Acros 100, which I have a good supply of. Any help is appreciated.
