Often when making Layer Masks with selections created by using tools such as Channel Pulls, Color Range, or even the Magic Wand holes can be left behind that can cause problems in your image.

Great job Dennis. Get this stuff to Heidi so all the members of APA can learn from your wisdom.
Really nice tone and delivery here (plus the great, useful information). Glad to see you are making these.
