REVENUE STAMPS ARE A TOOL FOR DATING PHOTOGRAPHSAs part of the effort by the Congress to fund the Civil War, among a number of taxes levied was an 1864 Act which provided that sellers of photographs affix stamps at the time of sale to "photographs, ambrotypes, daguerreotypes, or any sun pictures", according to the following schedule, exempting photographs too small for the stamp to be affixed: Less than 25 cents: 2 cents stamps (blue/orange). Values for all of these stamps appear in the Scott's Specialized Catalog of United States Stamps.

Much of the demand for larger photographs could be satisfied by making larger negatives and larger cameras to handle them.The stamps date these photographs to the period of the Wartime Retail Tax Act, 1 Sept. They were popularized under the trade name Gem and the Gem Galleries offered the tiny likeness at what proved to be the lowest prices in studio history.Gem Galleries flourished until about 1890, at which time the invention of roll film and family cameras made possible larger images at modest cost.Apparently Talbot (the inventor) did not fully realize the importance of washing his prints long enough to remove all the residual chemicals, or perhaps his fixing was inadequate. Instead of a glass cover, the photographer covered the tintype with a quick varnish to protect any tints or colors added to cheeks, lips, jewelry or buttons.Either fault leads to the same result: fading image, discoloration, etc. Popularity: The tintype was very popular during the Civil War because every soldier wanted to send a picture of himself with his rifle and sword home.I found this article on the Internet and thought that some of you who appreciate (and maybe even have a few) old photographs laying around in cardboard boxes or in desk drawers might like to read some tips on ways to try to put a date on when they might have been brass decorative frame.This sealed packet was then force fit into a special wood case and was often padded with velvet or silk. The first step was to make a negative image on a light sensitive paper.Flaws that were not obvious in the smaller cards now became very visible. Success in retouching led to innovations in the darkroom and at the camera.Diffusion of the image reduced the need for retouching. Blue playing card stamps are known to have been used in the summer of 1866 as other stamps were unavailable as the levy came to an end.These defects are now noticeable in many calotypes, some of which are today little more than pale yellow ghosts. They could be mailed home safely without fear of shattering.AMBROTYPE (1854 to the end of the Civil War)The ambrotype is a thin negative image on glass made to appear as a positive by showing it against a black background. It couldn't withstand travel or being carried in a locket as a daguerreotype could. The tintype actually does not contain any tin, but is made of thin black iron.
