Oh dear, that edit came out HUGE ... and we resized it to 50% its size, Sabine, didn't we, and then it really looked much smaller!
Well, I guess it will go beyond Sabine's capacity to write text in English to explain her technique ... I showed her how to lasso and feather things in PS and how then to shift the colours within that lassoed part. That was the whole trick, actually.
She spent quite some time to get rid of the tiny blood vessels in her eye (hated those when she first saw this one of my pics of her eyes ... actually I took a good many) but not get that part look too white or too tampered with. I don't know what she did about that, actually. After I had showed her the lasso-tool and feather thing, she went on working on it all by herself.
She does know that where the white meets the iris, there are flaws. But she did not know how to further get rid of those.
And Moshe ... she's only 13 and only just beginning to start and play with Photoshop, which may account for the flaws that you see.
