Solarization (physics)

(: Sabattier effect actually ) exploited the sensitivity of photographic films for alienation of photographic images as with solarization as a photographic effect is in the pseudo - solarization.

We speak of pseudo - solarization when the film (negative ) during the processing of partially or completely diffuse re-exposed and is then fully developed. In marginal areas already developed silver and silver bromide or silver iodide post-exposed it comes through the Eberhard effect to the expression of edge lines and contours, which are used as an artistic effect or to alienating gain of contrasts. The pseudo - solarization is also possible for a positive. The effect is more pronounced usually somewhat weaker.

With digital photography, pseudo - solarization is intrinsically impossible, but can be modeled as part of the post-processing of images. Modern image processing programs allow not only the alienation of the total brightness, but also the separate processing of individual color components (RGB or CMYK).

A pseudo - solarization similar image effect could be achieved with the Agfa Contour system is no longer available.
