The
definition of smooth-grain and rough-grain film stock.
Smooth-grain
film stock produces an image that is extremely smooth, or slick.
Rough-grain
film stock produces a rough, grainy-textured image with harsh contrasts between
blacks and whites and almost no subtle contrasts.
A
cinematographer may use both types of stock for different effects in films. For
example, a romantic love scene would probably be shot with smooth-grain film, a
riot or a furious battle scene with rough-grain film. So, the same colour in
film can also bring different effects by using different film stocks. Smooth-grain
film stock can create fine tones, artistic shadows and contrasts. Because of
the clarity and artistic perfection of these images, they often have a more
powerful visual impact the does reality. Rough-grain type often associated with
documentary here-and-now quality. Thus, we can change different effects in
post-production phase to make the frames and tone more close to the scripts.
