Nineteenth-century experimentation with photographic processes frequently became proprietary. The German-born, New Orleans photographer Theodore Lilienthal successfully sought legal redress in an 1881 infringement case involving his "Lambert Process" in the Eastern District of Louisiana.
A surface of very pure silver is preferable, but sterling (92.5% pure) or US coin (90% pure) or even lower grades of silver are functional. In 19th century practice, the usual stock material, Sheffield plate, was produced by a process sometimes called plating by fusion. A sheet of sterling silver was heat-fused onto the top of a thick copper ingot.
Technical problems delay the first use of dye sensitization in a commercial product until the mid-1880s; fully panchromatic emulsions are not in common use until the mid-20th century. 1876 – Hurter & Driffield begin systematic evaluation of sensitivity characteristics of photographic emulsions — the science of sensitometry. 1878
A portable photography studio in 19th-century Ireland. The wet collodion process sometimes gave rise to portable darkrooms, as photographic images needed to be developed while the plate was still wet. Animation illustrating the detail found in a wet-collodion photograph taken in Hill End in 1872.

The concept of combination printing stemmed from the desire to create more of a fine art within photography and often more idealized images. [1] Combination printing was popular in the mid-19th century due to the limitations of the negative's light sensitivity and camera technology. For example, the long exposures required at the time to create ...
Pictorialism is an international style and aesthetic movement that dominated photography during the later 19th and early 20th centuries. There is no standard definition of the term, but in general it refers to a style in which the photographer has somehow manipulated what would otherwise be a straightforward photograph as a means of creating an image rather than simply recording it.
