Solarization, also known as the Sabatier effect, is a photographic technique that involves partially reversing the image tones of a photographic print or film during the developing process, resulting in a dramatic and surreal effect. 

The process involves exposing the photographic material to light during the development phase, which causes the highlights to become darker and the shadows to become lighter. This creates a line of inversion along the edge of areas of contrast, creating a glowing outline or halo effect. The result is a stylized image that appears to be partially negative and partially positive.

The name "solarization" comes from the technique's original use of sunlight exposure during the reversal stage of development. The technique has been used by various artists and photographers over the years, including Man Ray, Lee Miller, and Jerry Uelsmann. 

Today, solarization can be achieved both in the darkroom and digitally through image manipulation software. In the darkroom, solarization can be achieved by exposing the photographic paper to light during the development phase, while in digital image manipulation, the effect can be created through software filters that can invert the tones of the photograph.
