WebbA conventional camera obscura uses a flat mirror that is an inch or two wider than the lens diameter and also about 1.5 times longer than its width. The difference between length and width is cause by the need to place the mirror at 45° to the lens optical axis. For example, a lens of 6-inch diameter would require a flat mirror of about 7×10 ...
