Digital Camera Color Correction Filters

•  The light of a clear sky, which lightens the hard shadows caused by the sun, has a color temperature much higher than daylight (5,600 ºK). To counteract the excessive predominance of blue in photographs illuminated only by light from the sky a Skylight filter can be used, of a pale amber tone.

•  The light of the first hours of the day are considered of a color temperature very inferior to daylight , and therefore it's conversion is advisable.

In a studio, on the other hand, balance is the starting point. Any correction in color that we need is at our disposal with compensation filters (CC) in series of different densities of the secondary colors, yellow (Y), magenta (M), and cyan (C), and primaries, blue (B), green (G), and red (R). The density is indicate with a number, that together with the colors first letter, indicates the filter. With these filters we can very precisely regulate the intensities of light of the basic color and, therefore, of the densities of the three layers of the emulsion.
