   I think the magazine you refer to was _American
Photography_. This was a high quality magazine published in
Boston. Eventually it became a combination of several
earlier magazines. I have a small collection of them. It was
the bastion of "pictorialism" and had many articles on
alternative processes. About 1940 it merged with a large
format magazine published by McGraw-Hill aimed at commercial
photographers and adopted the larger format. It continued to
be published into the early fifties but died then. The
1930's period magazines are quite intresting both for the
technical articles and the pictorialist viewpoint they
   One shot cameras were used for color advertising and
magazine illustration for perhaps 20 years. They were
finally killed off by Kodachrome and later by Ektachrome.
Especially the latter which could be developed by the
photographer. Usually, the color separation negatives were
printed by the three color carbro process and that
photographed to make the color printing plates. Kodachrome
transparencies could be photographed directly by the process
camera resulting in sharper images and better color.
Nonetheless the control offered by the camera and printing
method kept it in use long after Kodachrome made its
appearance in sheet film sizes. Dye transfer printing was
also used for the color seps but that did not become
available in a reliable form until the mid or late 1940's.
   Labs who made color carbro usually did nothing else. It
was evidently a difficult process to control.
