******  All the things said about the window in reference to slides applies
to prints as well. I work mostly with computer images and prints. It's all
the same phenomenon though with different actions available, like trimming
what becomes excess material. Whatever media you use, it's very valuable to
explore the wndow's behavior in a computer.

******  True, slides can't be enlarged as easily. They can however have
smaller masks applied which would amount to the same thing. Enlarging
happens in viewers or in projection. Masking defines what parts of the image
get used.

*****  Your strategy would work but you have to enlarge the man, and NOT
change the center-to-center spacing of his L&R images. That spacing defines
his spatial location relative to the window. This kind of thing is easiest
to do in the computer before making your prints as you need to move the
man's image separate from other surroundings.
