Wet plate photography, developed in the 1850s, is a historic photographic process that involves using a light-sensitive collodion mixture on glass or metal plates. This technique was widely popular in the 19th century due to its ability to produce highly detailed images with a unique aesthetic.

The process requires the plate to remain wet from exposure to development, making it both labor-intensive and time-sensitive. It begins by coating a glass or metal plate with a collodion mixture, which contains cellulose nitrate dissolved in ether and alcohol. The plate is then sensitized in a bath of silver nitrate, which makes it light-sensitive. After this, the plate must be exposed to light in a camera, typically within 10 to 15 minutes of coating, before it is developed in a darkroom. The result is a one-of-a-kind image with remarkable sharpness and tonal depth.

Though wet plate photography has largely been replaced by modern photographic techniques, it remains a revered art form. The process can produce stunning portraits and landscapes, often with a vintage or antique look that modern digital photography cannot replicate. Today, some photographers still use wet plate collodion for artistic expression, enjoying the challenge and the distinctive quality of the images it produces.

Despite its complexity, the wet plate process has seen a resurgence among photography enthusiasts and artists interested in historical techniques. It requires a significant amount of skill, precision, and patience, making it a rewarding but demanding method of image-making. The tactile, hands-on nature of wet plate photography allows for a deep connection between the artist and their medium, yielding images that feel timeless and deeply personal.

I had the pleasure of doing wet plate photography myself, in a workshop led by Peter Kunz, an amazing artist from Nuremberg who is worth checking out.
