Wet Plate Collodion process, also known as Tin Types, is an analogue process perfected in circa 1863. It helped to popularize photography and photo portraits on a proportional scale similar to the advent of smartphones. The process involves pouring collodion (a syrupy solution of nitrocellulose in a mixture of alcohol and ether) on a black metal (or glass) plate that is then made light sensitive with a solution of silver salts. While still wet, the plate is placed into the camera using a film holder and the exposure is made, after which it is processed using chemistry to reveal the latent negative image and then fixed into a positive image.
