I'm going to make myself a frame with a cut out aperture so I can have a look at framing and composition on location without having to unpack the camera and set it up etc.
As far as I can tell (please correct me if I'm wrong!), if I cut an aperture out of a piece of card, and hold it at the same distance from my eye as the focal length of the lens, then that should give a pretty accurate framing preview??
For example, a 4x10" aperture in a frame, held 210mm away from my eye, will give the same view as in camera 210mm lens on 4x10" format?
Therefore, would a 2x5" aperture in a frame (as a more compact alternative), held at 105mm (1/2 of 210) give the same?
Or have I got this totally wrong?!
Yes, you have the idea. If you tie a string to the card with a knot at 1/2 the focal length of each of your lenses, it will also assist you in choosing the best lens for the image.
And I'm posting this in
Style and Technique rather than in
Gear although I guess it could be in both
