Green Eye Flash Correction

I'm working on perfecting my green (or in this case yellow) eye correction on Shasta's photos, and I'm pretty happy with how this one turned out.

I made this edit in GIMP. I used a brush size just slightly larger than Shasta's actual iris set to 35% opacity and a very dark brown-black.

I set the opacity low because I like to be able to control how dark I make the correction. With opacity set to a low number, I can click repeatedly until I get the effect I like for the particular photo I'm editing. Also, since I'm not completely obscuring the underlying photo, I can see exactly where to place the highlights. I chose a dark brown-black because, for this photo, using pure black looked "obviously edited."

To add the highlights, I selected a brush approximately the size of the original highlights, set to white and also with 35% opacity. Again, I clicked until I had the right effect.

Here's a side-by-side of the before and after.

I'm just glad I don't have a cat.
