Term: Continuous tone

Definition:
Generally referring to pictorial images where there is a non-broken range of tones from white to black that may have every shade of gray represented. There are theoretically an infinite number of tones. Traditional photography (photochemical photography) produces continuous tone images. When reformatting pictorial items, it is important to distinguish continuous tone originals from printed halftones, since these two classes are likely to require different strategies and methods for making the digital images.
