The Bechers used view cameras as they were appropriate for the task they set themselves, the negatives were very big, probably 5x4. Bigger camera formats have less depth of field so if the background detail was irrelevant, this helps throw the background out of focus. Due to the size of the negative, the quality of the image was impeccable and enables the prints to be enlarged. As the Bechers intended to use their work in exhibitions. This format was therefore appropriate.
A - front lens and panel
B - this is the 'darkslide'. It's basically a film cassette that has two sheets of film. This slots into the back part of the camera.
C - bellows - these compress and stretch as the camera 'standards' along the rail G.
D - lens which has the shutter speed and aperture setting on it.
E - these are the controls that change the focal length and focus the camera.
F - tripod needs to be a decent size.
