Light energy alone, usually from the sun, reacted with the light sensitive chemicals on the paper’s surface to produce an image.

They only needed to be fixed to preserve the exposed image.

The photosensitive solution used in this process soaks into the paper, so the original paper surface remains dominant in the final print.

This gives these images a very matte look not normally associated with photography, and making some easy to confuse with collotypes.

Observing this shiny crust, no mater what the color, is a quick and sure way of telling if you are looking at a real photo.

A common problem with real photo postcards is that they are often devoid of any descriptive text.

This too is not foolproof for many publishers had large stocks of photo papers using them for decades after they stopped being manufactured.

NOTE: There were many other photo papers manufactured in addition to those listed on this page, and even these could be made in different finishes from matte to glossy.

The presence of a photographers name is not a definite indication of when a card was made or even who made it.The simplicity of the process made it very attractive to amateur photographers.Printing out papers fall into two categories, those coated with metallic salts, and those with coated with an emulsion.Collotypes, which provide the finest detail of all printing methods are sometimes confused with real photo postcards.But even collotypes will exhibit a discernible grain when magnified.
