| | Photographic: 35mm Film Buyer's Guide |
 | | A film's sharpness is a function of grain size, acutance (how distinct an edge there is between adjacent light and dark areas) and resolving power (how many line pairs per millimeter the film can separate), among other things. |
 | | Films are often listed by their ID code rather than by name in film-store ads, and working photographers often refer to films by these codes instead of by name. |
 | | For each film, we provide (where available) the ISO rating, the granularity rating (RMS for most manufacturers; Kodak's Print Grain Index for Kodak color-print films), resolving power (in lines per millimeter, for high- and low-contrast test targets), the film ID code, and a brief description of the film, plus a photo of the film box. |
