Opacity – The sum of the parts :huh:

Ofnuts,

Your post was very interesting and instructive. It gave me a better understanding of using opacity with Gimp.

Quote:PS: And in case you wonder why the gray value is 156, it happens to be the value of a gray that has the same average luminosity as a layer where 2/3 of the pixels are black and 1/3 are white...

Yes, you correctly anticipated it, this is definitely something I would be wondering about.

But... wouldn't it be the opposite? In this case, wouldn't it be 1/3 px black and 2/3 px white? 

Thanks!
