Hello afx, I think the slowness is primarily due to the glacial speed that
the scanner transfers data to the computer. Sometimes ten minutes just to
get a scan.  I have a G4, maybe it is old and slow, maybe new computers are
much faster.  The other time consuming part is making the selection, you
can't just reach for tools, you have to lasso your area to be fixed up, then
apply the feathered selection, then do levels/curves adjustments on the
selection.  Or else the other way is to use history erase.  either takes ten
more steps (approximately) compared to using a simple dodge/burn tool.
Still, IMHO, it gives a much better result because you can optimize the
levels and curves for each section of an image, no limit, you can have
everbody's faces, for example, individually leveled and curved and color
corrected.

I wish i knew of a program that allowed dodging/burning in 16 bit, do you?
