Digital Imaging Artifacts: Blooming and Clipping

In a typical scene, ranges of light values are very wide. And if reflected from diffuse or specular objects or light sources such as the sun or a candle lit up in the dark, levels of these light values may well exceed 10 stops. When such harsh light is exposed onto the image sensor, the pixel capacity to register this info may be exceeded, and the charge may subsequently leak into neighboring pixels, thus causing blooming to occur. Blooming is usually seen as really bright areas where the charge overflow occurred.
