Color print film is the most common type of photographic film in consumer use. Print film produces a negative image when it is developed, requiring it to be reversed again when it is printed on to photographic paper. Photographic film a sheet of plastic (polyester, celluloid (nitrocellulose) or cellulose acetate) coated with an emulsion containing light-sensitive silver halide salts (bonded by gelatin) with variable crystal sizes that determine the sensitivity or resolution of the film. ... In photography, a negative is a rectangle of material (nowadays usually photographic film) coated with chemicals that, upon photographic exposure, cause the material to record the colors or monochromatic shades of the scene in inverse, negative form. ... Until the advent of digital photographic processes, the sole meaning of Photographic Paper was paper coated with light-sensitive chemicals. ...
Almost all color print film made today is designed to be processed according to the C-41 process. C-41 is the name given to the process for developing a specific type of color film used in photography and often to the type of film itself. ...
I reasoned that it was much easier to hand around 4" x 6" colorprints for people to view than it was to drag out a slide projector and screen for a slide show or to force people to view 35mm transparencies on a light table with a focusing loupe.
A second advantage to using color negative film is that the exposure latitude of printfilm is greater than the exposure latitude of color transparency films, especially when image tones approach the lighter end of the exposure scale.
Color transparency films must be exposed carefully to retain details in the highlight areas of the images.

Black and white reversal film exists, but is uncommon — one of the reasons reversal films are popular among professional photographers is the fact that they are generally superior to printfilms with regards to color reproduction.
Some films, like Kodak's Technical Pan, are not ISO rated and therefore careful examination of the film's properties must be made by the photographer before exposure and development.
