Of course you realize that for the digital camera you do not need a monochrome filter. How many color paper sheets, as we said above, you will find, so many you have free color filters. This is one of the advantages of digital cameras to film. Moreover, manufacturers themselves claim of digital photography: the difference between the application enhances the filter series 80 when shooting indoors with a white balance preset in the daylight and without the filter and the filter with the white balance on the filament lamps, will be only in shades. If you need to take pictures in a room set the tone light, it is recommended to set the white balance manually (the usual way to the white paper) and color filter are not to be setup on the camera lens, but on the outbreak.
A particular conversation will be about the infrared filter, RED-25 or R2. Interestingly, when color photos are taken with this filter, especially withdrawn in the matrix, rather than a special infra-red black and white film (Kodak HIE, for example). Everyone knows the inability of black and white materials «distinguish» red hues. How to distinguish between the matrixes, you can see in the end photos.

Programmers know that any color can be represented in the RGB (Red / Green / Blue), i.e., by mixing in different proportions of three primary colors - red, green and blue. For example, purple (magenta) is obtained when mixing red and blue (additive coloring), yellow - red and green, etc. I recall shades are obtained by changing the brightness of colors. Thus, the brown color is a yellow tinge. Mixing red, green and blue in equal proportions, we get white.
This is what some photographers use.
Having the camera fixed on a tripod and made three consecutive exposures, for example, a waterfall, each with a different filter (one of the three primary colors) are shot tones normal, but with a lot of beautiful colored reflections. Try to do this if your camera has a film-style multiple modes, but do not forget to set the shutter speed each time by one-third of face value, measured through the three filters together. By the way, the three filters together, should provide a neutral gray color.

One of the features of a digital camera is to setup so-called white balance. This is to ensure that the red nose on your neighbor’s cottage turned red, not blue, that wedding picture groom presents his bride white flowers of purity and innocence, rather than yellow, a red rim on policemen’s cap, and not green, like on a forester.
What exactly should be done to properly set the white balance, you know very well - this is written in the user guide for your digital camera. Typically, the camera is fully automatic mode - auto, several pre-treatment, - fine, cloudy, Tungsteen, fluorescent, speedlight, and set the white balance mode manually - «preset». Names and nomenclature in different cells may differ, but the essence of this does not change.
