Re: Why do rulers appear bent, and how to fix?

could it be lens distortion which can be fixed in camera and in some pp programs. just a thought. could be wrong but thats the first thing that popped into my mind. r

I am taking photos of antique artifacts and using a yard stick to have as a
size reference in the photo. Interesting result though...even though the
artifacts appear just fine, the ruler comes out looking bent. I assume it has
something to do with the optics...near the edges of the photo etc. Is there
any software that can correct this effect? I have Photoshop but I am not sure
if this does this or if there even is anything that can fix this effect.
