4 - Press Cameras

The journalist needs a sturdy camera, which can be set up to take pictures quickly, and can be used by hand or on a tripod, and the focus can be made on a large plate for accuracy of work.
The camera shown in picture (11) combines all of these specifications. Because of its multiple capabilities, it is also used by advanced amateurs and by professionals as well as press photographers.

E- The studio camera or View Camera

This camera is the standard machine for commercial uses. It was first used to capture landscapes, and is now used as a studio for architectural photography. Picture (9) shows a type of these cameras. This device is more bulky than a photojournalism camera, and it is used in a fixed position.

6 - Polaroid Camaras

This type of camera is radically different from the rest of the cameras. The machine was developed by Dr. Edwin H. Land, known for his research on polarized light and polarized filters.
This camera uses a film consisting of two layers: a negative layer and a positive layer, where the final image is printed.
The film is exposed to the image projected from the camera lens in the same way as regular cameras, and after that several operations are performed that can be summarized as follows:
The two layers of the film pass through cylinders that squeeze and extrude a gelatinous chemical substance on the sensitive layer of the film, which plays the role of the appearance and fixation of the image. The positive image is dried for a few minutes in the open air.
