Question: How FOV is calculated?

The formula that it implements is FOV = 2 arctan (x / (2 f)), where x is the diagonal of the film. The FOV is measured across the frames diagonal, and is therefore smaller across the horizonal dimension, and even smaller across the vertical dimension.

How is a camera field of view determined?

The most direct way to determine the field of view is to measure it directly, typically with a tape measure. For example, point the camera at a wall. Looking through the camera (viewfinder or monitor), measure horizontally across the entire field of view right at the edge of visibility, to obtain the width.

What is darkroom process?

A darkroom is used to process photographic film, to make prints and to carry out other associated tasks. It is a room that can be made completely dark to allow the processing of the light-sensitive photographic materials, including film and photographic paper.
