Nevertheless, in terms of film sensitivity,
you should try to use the slowest film your photographic situation allows. Compare
a slide shot using an ISO 64 film with one shot on an ISO 400 film.
Colours will
be richer on the slower film, details are much more sharper. Like so much else in
photography, film speed is a trade off. As mentioned earlier, colour film is divided
into both negative and slides film but there is another category that only applies
to only colour film alone where b/w film doesnít: Colour Temperature Balances.
Colour film is either daylight or tungsten balanced. Daylight film, which is balanced
at 5500° Kelvin colour temperature, is good for all general shooting. Tungsten
film is balanced for either 3200° or 3400° Kelvin and is designed specifically
for professional use indoors with tungsten-based light sources (most yellow-coloured
household bulbs) or studio lighting. If you use daylight film indoors without a flash or colour compensation filters
(Type 80A or 80B), the image will have a yellow or orange colour cast overall. Tungsten-balanced
film gives superior results when used in such indoor-type lighting since its lower
colour temperature quality reduces the warmer colour balance produced by the tungsten
lights.
