I use provia for my people shots, as well as alot of wildlife, provia is claimed to be the finest grained slide film on the market as well as being more neutral, I have also used it alot for doing artwork photography for catalog placment, I like provia alot more than I like astia, velivia of course is the king of saturation, but provia is a great film as well and has served me well over the years, I know many pros that won't shoot anything but provia.
