Not all photo realistic images are photographs and the collector
should know the difference between a photograph and non-photograph.
The realistic images in a recent glossy magazine, on a modern
trading card, cereal box or advertising poster are not photographs
but photomechanical prints. While a photograph is made by the
subtle interaction of light or other energy with photochemicals,
most photomechanical prints involve a printing press pressing
ink against paper.
Names for common types of photomechanical prints include lithograph,
collotype, photoengraving, giclee, photogravure, computer print,
halftone and digital print.
Even when they collect both, most photo collectors consider
photographs and photomechanical prints different categories.
This is due to aesthetic as much as technical reasons. Typically
a photograph will be more expensive than the equivalent photomechanical
print. In the genre of photographs the seller should represent
a photomechanical print as photomechanical and not as a real
Telling the Difference: "Dots Versus No Dots"
A handheld microscope or strong magnifier will allow one to
distinguish a photograph from a photomechanical print.
Close examination of a photograph will reveal great subtly
in tones and shades. The tones can be so subtle that it seems
as if you can't get the microscope in focus.
Under magnification the photomechanical print will be made
up of a distinct pattern of tiny dots or other printed ink patterns.
The dots can be all one color or, for a color picture, a variety
of colors. Check this out yourself. Take a microscope or strong
magnifying glass and examine the pictures in the magazine on
your coffee table.

Many cheap reprints are photomechanical reproductions of original
photos. However, some photomechanical prints have financial value,
such as a Scavullo silkscreen, Alfred Steiglitz photogravure,
Richard Avedon giclee or a many sports cards.
While this book is about real photographs, a chapter near
the end gives an overview of the different kinds of photomechanical

Guess What. You've just learned how to identify many modern
reprints and fakes
If you see an 'antique' photograph, like an 1860s Abe Lincoln
cabinet card or 1910 Ty Cobb smapshot, where the image is made
up of a multi color dot pattern like on a modern trading card
or magazine cover, it's more than probably a modern reprint.
