Term - Noise
|Noise||SWPP Photographic Glossary|
Wednesday 4th March 2015
Random coloured pixels that appear in dark or shadow areas when the light levels are below the camera's CCD sensitivity range. Noise is also often seen from scans made using a scanner that doesn't have a wide enough dynamic range to cope with the shadow and highlight areas in one scan. Some image editing programs have a Noise filter that adds a grain pattern to the image to make it look more like a natural photograph taken using film.
