Optical Center

[Bruce Osgood]

I've lost my information on finding the optical center for placing a print on a matting board. I found it here on APUG and have been looking thru old posts but can't find it again.

Can anyone refer me to the thread or give me a link?

Thanks,

Found this lurking on my hard drive - hope it's what you're after.

That's it. Thanks a lot.

there is also a good example of this in beyond monochrome in the mounting chapter too.
