When you switch from the two inner lenses to the two outer lenses, you
simply advance twice instead of once, and only waste one frame each time
you do this as long as you do cover the lenses when you click the
shutter prior to the second advance. (Each time you advance a modified
Nimslo it advances 2 frames like a Realist rather than the usual 4
frames when used in original lenticular mode.) I don't know how to
advance without clicking the shutter first, if there is a way. It seems
to work fine just to cover the lenses though. Same routine and you waste
one frame switching back to closeup mode. -Linda
