Mathieu is a wet plate photographer based in Truro, Nova Scotia. Working with the 19th-century wet plate collodion process, he creates one-of-a-kind handmade photographs in the form of tintypes and ambrotypes. Each image is crafted entirely by hand using glass or metal plates coated in light-sensitive chemicals and developed with pure silver. The result is a unique, tangible object with remarkable detail and archival permanence—wet plate photographs, when properly cared for, can last for centuries.

In addition to his work with wet plate, Mathieu also explores photography through a variety of film formats, blending traditional techniques with a personal, modern vision.
