Alex Boyd is known for his landscape work with antique processes such as wet-plate collodion.

Wet-plate collodion is a slow process and requires the use of chemicals on location. The process was pioneered by Frederick Scott Archer and Gustave Le Gray in the early 1850s. Until it was largely replaced by other processes in the 1880s, it revolutionised photography, making it easier to obtain images with exposures of only a few seconds, and allowing multiple copies to be made from the same glass negative.
