Camera Obscura
The very first stage of camera photography is Camera Obscura. This is also referred to as the Dark Chamber. The Camera Obscura is a room with no windows and only contains one tiny whole with a lens, projected images from the outside of the room onto the far wall inside it. The image was upside down and not very clear. The image was then traced by great artists.
Daguerrotype Camera
The Daguerreotype was named after Louis Jacques Mandee Daquerre. This was one of the first images to be fixed on a silver plate. A reaction is made between silver, iodine and mercury vapour and then 'fixed' with a salt solution. The image was very clear but only one permanent image could be made so you couldn't make multiples.
Talbotype / Calotype
Calotype or Talbotype is an early photographic process introduced in 1841. This was produced by a negative paper with silver. It was created once a paper was exposed to bright light causing a positive image. This was able to produce multiple copies of a single image. Even though it wasn't as clear as the Dageurro type because of the multiple copies.
Collodian Wet Plate
It was one of the best methods compared to the methods above because it produced a clear image that could reproduce multiple times. A clean glass which was evenly coated with colloidal. After the plane had to be dipped into a silver nitrate solution then inserted into the camera and exposed. Immediately it had to be developed and dry. In worst case scenario, if the plate dried before the process the image would be destroyed.
