Masks give you a lot of control over things, plus, until you apply them, they are non destructive.

Here is one tutorial on them :

And another :

They are also very handy for doing effects in GAP.

I'm trying to learn about layer masks. I'm probably missing something important, but seems to me that one can get the same result with less effort by simply erasing what one does not want in an image, and keeping what is left.
Or is there something different achieved by masking? Thanks,

Have a look at http://meetthegimp.org/ there are several good examples of using layer masks.

Tried both of these but Firefox can't find them. I wonder why?

appears to be down, not responding to pings and address is unresolvable. Maybe they have not paid/renewed their domain/fees??? -

Guess they have server problems...again....

When I sent the email, I went to the actual sites and cut and pasted the address. Give it a bit, then try again.
