Colored filters are used to alter the printing light to
obtain proper color balance, much the same as is done

black when unexposed. Dust particles and scratches also
appear black. To make a test print lighter, you must
increase the exposure. Dodging darkens selective areas
of a print, and burning in lightens selective areas of a
print. Color corrections are performed the same as the
visual appearance requires.

high-volume production is routine in an imaging
facility, automated printers are an invaluable piece of
photographic paper that must be taken out and processed
through a processor. Other more sophisticated types

operated under normal room lighting conditions, and
they are very useful when a large number of the same

to rush production. In these systems, the printer and
processor are combined into one unit. The printer cuts
the paper to size, exposes it, and automatically feeds it
through the processor. Minilabs (as they are called) are
used in all of the "One Hour" photo-finishing shops that
you see today.

printer is controlled by a keyboard (fig. 12-9). Some
systems have zoom enlarging lenses to alter the image
size. The negative can be aligned and composed by
adjusting the negative carrier. These adjustments to the
image size and cropping can be seen on a viewing
