I used 2 cams and the "3d glasses" effect in After Effects to create a simple video which requires red/cyan glasses. However, my settings were all guesswork.
I would rather know what it will look like before I start filming.
Sadly, I was not taught 'Optics' at school (40 years ago).
After reading about some of the maths, I think the only information I don't have is the "focal length" of my camera. (Please hold back the sniggering; it is a cheap FLIP 1280*720 camera).
How can I calculate the 'focal length'?
I can measure the vertical and horizonal angles (fields of view), I can measure how close an object can be before going out of focus. I could measure the angles of distant and close objects.
But. What can I do with the results? Can I calulate the Focal Length.
The following 2 links may give a good idea of the area where I am currently lost:-
