In printed images the grey areas are usually made up of black marks that are spaced to create the optical illusion of greys. Though most of us today are familiar with the concept of photo grain, this is mostly because we have experienced very large prints made from small 35mm negatives. But even here the effect is more of a softening of detail than a observable texture.

They tend to be vulnerable to contamination and can easily deteriorate. They were much faster than collodion based papers and were able to be exposed indoors under gaslight lamps gaslight paperbut they remained slow enough to be used only in contact printing.

Its ease of use made it the most popular paper on the market for real photo postcards. They were manufactured with postcard backs. NOTE: Azo paper without postcard backs continued to be made until Because this required guess work to judge exposure time, these papers were not as popular at first as printing out papers. In Kodak introduced a developing machine for professional and amateur alike, and between and photo processing services for postcards were also offered to encouraged sales.

These papers weretimes more light sensitive than print out papers and eventually became the paper of choice. Their speed not only allowed them to be used with an enlarger but it increased production speed as well. Bromide Prints - Bromide prints are developed out producing a very stable image due to their large silver particles. They have a warm to blue-black color and are highly subject to tarnishing. While permanent bromide paper was developed alongside chloride papers, its cost, difficulty to process, and lower tonal range kept it from being widely used in America.

Large quantities could also be produced in consistant color because they did not require toning. However there was no demand for mass production until real photo postcards became popular. Bromide paper was relatively fast and was meant to be used with an enlarger. Rotograph and Kodak both manufactured bromide paper. The words Bromide Print often appear on these cards rather than a brand name, or they go unlabled.

Even the toning of photographs were pushed beyond the natural for expressive purposes producing very deep blues or sepias. Many of these hand colored cards that depicted women and children were produced in Europe while in America colored views were dominant.

Since they cannot compete realistically with color photography or printed photochromes, hand coloring on modern cards takes on a more stylized look.

Though white borders could always be created they a more complex option so the image on most of these cards was simply bled to the edge. This continued to be true even when Kodak introduced cameras that would shoot postcard sized negatives. The most common exception to this were cards shot through a stencil to provide a decorative white border. These stencils were usually cut out of tin or heavy paper and would be sandwiched between the photo paper and negative during exposure to the sun.

While these stencils could be purchased in stores and came in various designs, many forgoed the expense and made their own. Homemade stencils were rarely perfectly symmetrical and are a tell tale sign of non-commercially printed cards. Another clear sign of homemade real photo postcards are the ragged edges sometimes found on cards made with salted paper where the photo sensitive emulsion is brushed on. When the effect is exaggerated it is most certain that it was done so for stylistic effect.

Other cards that have an irregular or crooked line between the image and the border are more likely the sign of poor craftsmanship. The smaller negatives required postcard sized prints to be enlarged often with the aid of an easel to hold the paper in place, and white borders became more common.
