from The Century Dictionary and Cyclopedia

  • n. In photography, the angle included by a lens, determined from the relation of the focal length to the diameter of the field. If, in the figure, AB equals the diameter of the field and CD the focal length, then the angle ADB is the view-angle. When the ratio between the diameter of field and focal length is known, reference tables give the angle sought.


Sorry, no etymologies found.


  • A suggestion I had for detail in the Galley, since it’s too small to sculpt like the bridge, but everyone would like to see; how about a piece of back-lit film with an image as it would be seen through the window and/or skylight, possibly with a lens a little bit above the film, to increase the effect on the image from your view-angle as you move your head.
