Brings Pictures Back to Life


Color photos are subject to the same slings and arrows of outrageous shoe boxes that torment
black-and-white pictures—the dirt, the creases, the spills, the humidity, and of course
the fatal reactions that occur when the still-active chemicals of one photo-
graph are crammed up against those of another picture for a
decade or so. But the chemicals in color photos are still
more volatile and more susceptible to turning the only
picture of beloved Uncle Ernie into what looks like an
extraterrestrial blob of protoplasm. Luckily for all the myr-
iad misfortunes that can affect photos, we have an arsenal
of E.R. weaponry to bring them back from the brink. There
are so many tools in the digital darkroom, there’s no space
to cover them all in detail, but here are some of the most
common devices available in programs such as Photoshop,
Elements, and Paint Shop Pro to bring color—the right color—
back to the cheeks of fading ancestors.
