Does anybody know a formula to figure out the following: Say I wanted to take a picture of a wall that is 100 feet in width and in length. How many feet away from the wall would the camera have to be to capture he entire wall???
I obviously could measure the distance with a long measuring tape once I found my self in a position where the entire wall was in the picture, but my goal is to find the formula for the problem.
Thank you for your help.

It's the ratio of the focal lenth of the lens (say 100mm) to the size of the image (say 35mm). 35 mm = 1.37795 inch, the object is 1200 inch, so 1200/1.37795=870 times the focal lenth of the lens. 870 X 100 mm = 87,000 mm or 87 meters.

It depends on the focal length and curvature.
