If I want to blend a real photo (from scanner) with a pov image it is
difficult to adjust the camera position so that 3D viewpoints and angles
match exactly.
Are there any tricks for doing this quicly?
For example, if I make (and scan) a photograph from my garden, and then
want to position a virtual piece of art in it, can I relate pov-camera
settings to the lenses in my photocamera?
