Hmmm...for me, it depends on the situation. I'd say right now, I find the following to be my favorites: Night Street Photography - Ilford Delta 3200 B&W. Incredible low light capability with a finer grain than you would imagine for such a fast film. Also can be pushed to insane levels (some people shoot it at EI 25000) although I've only gone as high as EI 6400 (see Trolloween photos). Landscape - Fuji Velvia slide film. Almost non-existent grain and incredible vividness in blues and greens. It is, however, a slow film rated at ISO 50. Tripod is a must with this film. Carnivals/Parade/Bright Colored Subjects/Cityscapes - Fuji Provia 100F slide film. Fantastic color saturation, very fine to non-existent grain. At ISO 100 (and some people rate it at EI 64) it's not meant for anything close to low or medium light. High Speed color - Fuji Press 800 or 1600. Very fine grain for the speed. Many say that the 800 has the grain of a 400 and 1600 of an 800. The bonfire shot I just uploaded is the Press 800 (no flash, all available light). Of course, I use other stuff (considering the cost per roll of the Provia and Velvia): Kodak Tri-X and T-max, Ilford HP5 Plus, Fuji Reala and Sensia II. I am also extremely anxious to try the new Fuji Neopan ACROS b&w film (have about 8 rolls in the fridge right now). What I have seen impresses the heck out of me (deep, dark blacks and rich, creamy whites). -=>Donald
