In photography, 'clipping' is the loss image information in a region of a
photograph is brighter than what the imaging device can handle or outside the
color gamut of the space used to represent the photograph. It is an instance of
signal clipping in the image domain. Bright clipped areas are sometimes called "blown-out highlights". With
digital cameras, the clipped area will often turn to pure
white and will not contain any detail. For example, it is not unusual for a bright sky area to be clipped to white.
Clipping can occur in the
image sensor, where it is called ''saturation''; or at the
analog-to-digital converter (ADC); or in the processing and rendering to a standard
color space. Depending on where clipping occurs, and on whether
raw data is still available, the clipping may be repairable.
