I shot some last year. In 35mm dev'd in D-76 1:1, it produced nice even negatives, a bit less contrasty than roughly equivalent films like Plus-X and Agfapan 100. Made lovely 8x10s with barely visible grain. But I also slit some and tried it my Minox. Dev'd in XTOL 1:1, it was pretty unimpressive: clearly grainer than results from PX or APX 100 in the Minox (and not even in the same ballpark as TMX), even when just printed to 4x5.(posted 9002 days ago)Tonally, it's my least favorite of these films. At least in my camera and darkroom, the results lacked the fine grain and glowing skintones of APX 100, the unique luminousity of PX, and, of course, the tight grain and very punchy contrast of TMX. So... while it's a nice enough film, I would choose Agfapan 100, Plus-X, or T-Max 100 over it.
OTOH, if I had 10 free rolls of FP4+, I'm sure I'd enjoy using them, and I'd definitely end up with some very nice images... Have fun!
