RE: [APML] A PS curves question

["R. Scott Ireland" <ireland@gate.net>]

Alan,

Use a curves adjustment layer, so that you may go back and change it as many
times as you like.  Same thing for levels, saturation, etc., etc.  Don't
make such adjustments directly to the background layer; it is much easier to
use adjustment layers.  You may also then easily mask in/out parts of the
adjustment layers too, if you wish.

When the image is completely finished, then flatten it so that it may be
saved as a TIFF.  You may also want to save the file - unflattened of
course -  with all of the adjustment layers intact (big file!) as a
photoshop (.PSD) document, in case you want to work on it some more at a
later time.
