How
to Color Photographs:
Detroit
Publishing Company photographs were initially shot in
black and white. The photographer would take notes
describing the scene and the colors. After he developed
the photograph, the production manager would mark up the
color instructions on a print and a retoucher would color
the print. Color prints were then produced by lithography,
a process of printing from a flat surface on which the
image to be printed is ink-receptive and the blank area
is ink-repellent. The Detroit Publishing Company
held the exclusive North American rights to Photochrom,
a Swiss-patented method of color lithography.

The method of transferring a hand-colored photograph to
multiple printing plates uses separation negatives, one
for each color. The colorized original is re-photographed
through different colored filters onto black and white
negatives, one for each color. The negatives are
then transferred onto the printing plates. Up to
twenty color separations might be produced for one Photochrom
lithograph print. Note the progression from black
ink to nine colors in these examples of the company’s
postcard proof sheets from about 1900.
