Dictionary of Computers - digital retouching
digital retouching
Technique for touching up digital photographs, similar to airbrushing in the analogue world. It is commonly used in the film industry to remove scratches, change features, or to cover up filming mistakes.
In sophisticated programs, the retoucher points out the error to the computer and the computer calculates new colour values for the affected pixels from the colours of neighbouring pixels. Desktop versions, such as Paintshop Pro, have options such as the Clone Brush and the Eyedropper, which can achieve the same effect manually.
