CanoScan FS2710 Film Scanner

Negative/Positive Film

Color Negative Film

Negative film is used to make prints. The light and dark portions of the film are

reversed from the image. It permits a large degree of latitude (the extent to

which it is under- or over-exposed) so that even if a picture is slightly under- or

over-exposed (the amount of light striking the film) when shot, the problem can

be corrected by the developer when printed to paper. The negative film format is

recommended when you wish to shoot without being strictly conscious of the

exposure setting or when you wish to have the picture output as prints. How-

ever, the color of the film base (the color of the film itself) varies somewhat

between manufacturers and between individual products. For this reason, the

CanoScan FS2710 has to utilize a color correction process to reproduce colors

correctly. This process is conducted automatically by the CanoScan FS2710 auto

color balance function.

Color Positive Film

Positive film (reversal film) reproduces the colors on film as they are on the

photographic subject so that the colors of a photographed object are immedi-

ately apparent. This format is used when the pictures are viewed as slides or

when printing plates are being made. Compared to negative film, the latitude of

positive film is narrow, requiring the photographer to pay more attention to the

exposure setting. Since there is no effect on color reproduction because of

differing film base colors, the CanoScan FS2710 does not need to perform its

auto color balance function on films in this format.
