Noise in print


The amount of acceptable digital noise is subjective, like
so many other aspects of photography. Here’s a fun test,
guaranteed to raise the noise level in a room: assemble several
photographers, show them photographs with a variety of
different noise levels present, and ask for opinions. What’s
acceptable to one isn’t for all. The same holds true for publica-
tions. Newspapers, printed on newsprint, of course, can accept
more noise in their images than can a magazine printed on
higher-quality paper. This is because the newspaper press uses
a line screen of around 85 lines per inch. The paper absorbs and
tends to spread the ink from the printing press more readily.
Most magazines and other publications use higher-quality and a
fi ner-line screen, which produces crisper, sharper images. If
these publications showcase the good qualities of an image
better, it makes sense they’ll highlight an image’s imperfections
better as well.
Barry was fortunate to have been working at the Denver
Post when the digital revolution was really taking off. The
paper supplied him with camera, lenses, speedlights, and great
training in their use. When he returned to his own photography
business full-time, he was up to speed on the technology.
This advantage had its drawbacks, however, because many cor-
porate and editorial clients were afraid to accept digital fi les.
The most common excuse: “We have a digital camera and the
pictures from it are horrible, so we still hire only fi lm-based
