Rob Perisho received his BA in Photography from Columbia College, Chicago in 1997. For the next 16 years he worked as a freelance commercial photographer, technical assistant, & digital ingestion technician for a wide range of Chicago's leading advertising & architectural photographers.
As the digital age became more predominate in the industry, he began to feel distant from his craft. In 2007 he began reflecting on his college studies of the 19th century photographic process of albumen & salt printing. During his research he decided that he wanted to take it a step further and forego conventional film & make his own by learning the wet plate collodion process.
The process was created by the sculptor Fredrick Scott Archer in 1848 & published in 1851. His process combined the fine detail of the daguerrotype, with the ability of the calotype to be printed

multiple times. Archer willingly published his findings without filing a patent; his gift to the world. As a result, he made very little money from the wet plate process. In May of 1857 he died a pauper leaving behind his wife & three children.
The wet plate collodion process can be used to create an ambrotype negative or positive. Rob currently works with the positive process, on clear glass (CGAs / Clear Glass Ambrotypes). The processed glass plate is backed with black velvet or coated with asphaltum, to complete the tonal range of image. At this time, the work being displayed could be called "warts & all"; since he still considers himself in "a learning stage". Rob has decided to display the successes & the mistakes of this endeavour to show the evolution of his craft. In the future he plans to create ambrotype negatives & return to albumen printing.
