A Wet Plate Collodion Demonstration

In conjunction with his current Cleveland Print Room exhibition, Persistence of Vision, Greg Martin will present a Wet Plate Collodion Demonstration and Gallery Talk at 1 p.m. today. Martin graduated from the Cleveland Institute of Art’s Industrial Design Program in 1989, and has been working with the wet plate collodion process for nearly a decade. The collodion process dates back to the 1850s. It gained popularity quickly due to its ability to make virtually limitless reproductions, as well as its clarity and sharpness. However, it had a major disadvantage: the whole process, from plate coating to developing, had to be completed before the plate dried (roughly 10 minutes).This event is free for CPR members, and $20 for non-members. Greg Martin’s Persistence of Vision remains on view through Feb. 27. (Usmani)
