re: my original post, I APOLOGIZE deeply, but I was mistaken in
stating that they were from the same negative. In fact they are from
TWO separate negatives, one exposed for the highlights and another
exposed for the shadows and they were composited in the way I
described. Obviously, photos with the intent of compositing to
compensate for extremes in exposure require that they be taken from
identical (by way of tripod) or nearly identical points of view, by
reframing according to edges.

Sorry for the mistake, but the tecnique remains the same for layer
composite and erasing to bottom layer.

ciao,

Actually, what I think would be nice would be a variation of a feature
my old Canon T-90 had, a multi-spot mode where you point the 5% circle
in the middle on your highlight, press multi-spot metering button,
then point the spot to the shadow, and the meter averages the exposure
(imagine a subject on stage with a white t-shirt, then point spot to
black of background and camera calculates average exposure), the same
could be done digitally (theoretically).

Take a spot meter reading of darkest tone and then designate hrightest
highlight - and camera calculates and compresses range to hold detail
shadow in foreground of darkened room AND highlight in scene outside
window. A challenge for camera chip engineers...

Just my UNscientific opinion.
