- Abstract
What is the field of vision of the objective of a photographic camera? The answer to this question can be given from very simple principles of geometric optics; everything turns around the maximum image size, that is, the dimensions of the CCD or photographic film. As an added bonus, it is possible "to discover" the meaning of the "3 X" in these optical devices ("zoom") of more popular photographic digital cameras.
