Camera Obscura
The camera obscura is an ancestor of the modern photographic camera, its latin name means "dark chamber". It was used back in 1600. It had a darkened room with light emitted through a single tiny hole. The result was an inverted image used by artists to aid their tracing. Later portable versions were built.

Daguerrotpe
Talbotype/Calotype
Callodian Wet Plate Process
Best of both techniques because it was produced on a clear image that could reproduce multiple times. It was a clean glass plate evenly coated with colloidal. The plate had to be dipped in a silver nitrate solution inserted into the camera then exposed. It then had to be developed immediately and allowed to dry. If the plate dried before the process was complete the emulsion would harden and the photo would be ruined.
