All colour films are balanced for a certain type or quality of light, e.g. for daylight or for artificial light. If the light source does not correspond to colour temperature for which the film is balanced, a blue or red colour cast will result, especially with reversal colour film. Shots taken in the shade, for instance, will have a blue cast due to the blue light of the sky.
These defects can be overcome by using the appropriate coour correction filter. These filters change the wrong light to that for which the colour film in use has been balanced.
