This is something I brought up some time ago (see
The Gimp uses logarithmic scaling, while other image processing tools I
know use another kind of scaling -- I thought linear, but sqrt has also
been suggested.

At first I didn't like the way the Gimp does it, because I think it
doesn't look pretty. But then I started to think that logarithmic scaling
actually isn't so bad for these kinds of things.
