Playing with Chat-gpt

 There’s been a lot of talk about Chat-gpt and its capabilities. Out of curiosity I tried Chat-gpt with the phrase describe wet plate collodion photography. This what I got

Wet plate collodion photography is a photographic process that was popular in the mid to late 19th century. It involves coating a glass or metal plate with a mixture of collodion (a viscous solution of cellulose nitrate in ether and alcohol) and silver nitrate. The plate is then sensitized in a darkroom and inserted into the camera while still wet. The exposure time is typically several seconds to a minute. After exposure, the plate is developed, fixed, and washed to produce a negative image. The process is considered to be one of the first true photographic techniques. It was widely used for portrait and landscape photography and was especially popular for making cartes-de-visite and tintype photographs.

It might not be the best or most detailed answer out there, but it’s not wrong either (apart from the bit about tintypes - similar but different process), but I liked the mention of cartes-de-visite...
