Solarization

Full or partial conversion of coloured images result in over-exposed. If the exposure of the photographic material is excessive and goes beyond the linear section of the characteristic curve of the optical image density becomes inversely proportional to the amount falling on the emulsion of the light. Thus in areas where there is a similar "Peresvet", the optical density the less, the more exposure. Cause solarization in film photography believe oxidation centers of the latent photographic image neutral atoms free of halides, formed by the large exposure of the microcrystals of silver halide in the photographic emulsion. There is this effect and in digital cameras.
