Picked up a nice tintype photo off Ebay last week for $6. Very good condition, Portrait of young woman; 1/6 plate (2 1/4" x 3 3/8") Tintype , c.1875. Note hand tinted rosy cheek. Like daguerreotypes, tintypes are one of a kind photographs. They are not prints. A thin piece of metal is "japanned" (coated with a shiny black enamel and baked). Then the plate is coated with a collodion emulsion, sensitized, exposed in the camera, and finally developed. It is actually a negative image (and hence laterally reversed); the black background making the negative image appear positive.
The photo on the right is by the master English photographer Frank Meadow Sutcliffe. I've had this print since 1975. "Fishergirl", Polly Swallow of Church St. holding fish net, c.1880, Whitby, England, Sepia toned gelatin silver print made in 1975 from the original glass plate negative. 8x10 inches.
