Thanks. -- This will come in handy.
It certainly does work for the examples I previously uploaded.
-- BTW: I get a message saying I can't upload more than 256kB at a time, and another message saying I can't upload more than a total of 72.93 kB. WTF
-- Fix this. - Those surely are backwards, and increase the total limit.
My only issue is, it makes everything else semi transparent.
Refer this:
I had to add a red layer below to show where it is semi transparent, everywhere.
Not the effect I wanted.
I'm back to my original dilemma of trying to make a flood selection which fails because of shading, and "similar" colors.
Here's the flood selection, which is horrible for trying to achieve what I want, including in use with Color Clearer.
0% Tolerance | 30% Tolerance
In this particular case, in the full size image, 30% Tolerance selects less around the horns, and selects unwanted pixels all throughout the body.
Flood Selection is in no way a part of this solution.
I'd rather be hit by a meteor than service 20,000 pixels by pixel.
What else you got?
There needs to be a targeting tool with a circle shape, like the Paintbrush, which acts as a Masker, for dealing with edges etc.
