160 years ago the photographer was required to be equal parts chemist, technician and artist. Making photographic plates from scratch, the photographer was an Alchemist who possessed the power to conjure images of unmatched reality, using their photographic potions.

As an extra special treat at Gala this year we have Stephen Brûlé providing tin type portrait sessions in the McCuaig Gallery. Sessions are limited so book yours ahead of time to reserve. 

*Please note you must be attending Gala to purchase this product.

The Wet Plate Collodion Process

Invented in 1851, wet plate collodion is one of the earliest permanent photographic processes. It requires the photographer to coat a metal plate (Tintype) or a glass plate (Ambrotype) with salted collodion. In the darkroom the plate is submerged in a solution of silver nitrate where the salts become light sensitive silver halides. The plate is then loaded into a holder and brought to the camera for exposure which can range from 1 second to 8 minutes (the collodion’s sensitivity is around ISO 0.5). The collodion must remain wet for the entire process; the photographer only has about 10 minutes of working time before the plate begins to dry. Once exposed, the plate is brought back into the darkroom where it is developed, fixed and placed in a wash bath. The final step to complete the plate is to apply a gum sandarac varnish, which protects the silver image allowing it to last for centuries.
