I saw a few negative comments above on Fuji Provia 100 F, so I thought I should voice my support of the film. It has a more neutral color balance than Velvia, and thus is much more suited to product shots and portraits than Velvia. Actually, I've never used it for portraits, just product shots, but you definately don't want to use Velvia for protraits -- too much color brings out the imperfections in skin. For protraits, I usually shoot Fuji NPS 160 in 120 size with my Pentax 67. It also has a neutral color balance and does well with flesh tones. NPS is also good for architectural interiors because it is very tollerant of mixed light sources (daylight, tungsten, etc.)
