CROPPING

Cropping is an editing skill that was highly
developed during the days of black-andwhite
photography, lapsed somewhat in the color
slide era, and is now revived fully as an integral
part of preparing the final digital image. Even
when the framing as shot is judged to be fine,
technical adjustments such as lens distortion
correction will demand it.
Cropping is one way of reworking the image
well after it has been shot; an option for deferring
design decisions, and even of exploring new ways
of organizing an image. Unlike stitching, however,
it reduces the size of the image, so demands a
high resolution to begin with. In traditional
enlarger printing, the enlarging easel itself acts
as a cropping guide, but it may be easier to
experiment first with L-shaped cropping masks
on film (on a light box) or a contact sheet. With
digital images (or scanned film), the process
is infinitely easier and clearer, using software
cropping tools.
It is important not to think of cropping as
a design panacea or as an excuse for not being
decisive at the time of shooting. The danger of
having the opportunity to alter and manipulate
a frame after it is shot is that it can lull you into
imagining that you can perform a significant
proportion of photography on the computer.
Cropping introduces an interruption in the
process of making a photograph, and most
images benefit from continuity of vision.
