Fuji Provia 100F is a medium color saturation and contrast slide film. In general, slide film, or color reversal film has a rich, quality that gives these images a depth that's hard to produce with color negative film or digital images. It renders colors so vividly that they seem to jump out at you from off the screen. Compared to other slide film, Fuji Provia is more subtle in its colors and contrast, and its this subtlety that makes this film so interesting.
Provia is often overshadowed by Velvia, Fuji's other slide film. Velvia is bright, vibrant, and high in contrast. Its colors and contrast commands attention, more so than the actual subject of the image. Provia, on the other hand, is more subtle. It produces colors that have a wonderful, subdued richness. Instead of stealing the show, its colors and contrast compliment the subject of a photo. Personally, I find these color characteristics to work well with street photography, urban photos, documentary, and outdoor shots of people. The film, however does have its drawbacks.
In 2013, Fuji decided to discontinue the 400 and 800 film speeds and I was devastated. I find the 100 film speed too slow, even when I use it with a wide open aperture (f/1.4). On bright, sunny days I have no issue with this film, but with overcast and low light situations, forget it. Over half of my images come out blurry. A tripod can fix this problem, but I much prefer handheld photography. It bothers me to no end that Fuji took away the 400 speed of this film; they effectively eliminated the film's use as a medium for documentary and street photography.
There's no question the color and depth of slide film is in a league of its own. Digital sensors just can't compete. So, grab a roll of Fuji Provia and give it a try, I think you'll be pleased with the results.
