I'm not a darkroom specialist by any stretch of the imagination.  Probably
the toughest thing I've accomplished in the darkroom is creating shadow
shapes with screws, nails and other objects.  <g>  ( wonder if Ansel Adams
ever did shadow shapes?  Of course, the Zone System applies)

However, I have done a lot of double exposure images where I take a picture
of a flower, for example, where the first exposure is dead-on sharp.  The
second exposure is completely out of focus.  The results occasionally are
suprising in that these double exposed pictures can end up sharper than a
single exposure.  Is this effectively an "unsharp mask"?
