COPY A CATCHLIGHT
Catchlights are the little reflected highlights we see in a person’s eyes, and they’re great for focusing attention on the ‘window to the soul’. Sometimes catchlights can look a little dull, so try dodging them with the Dodge Tool. For greater impact, try cloning a weak catchlight from one side of the iris to the other. Make a new layer and grab the Clone Tool. Click the Clone Source Panel icon in the tool options at the top. Check Flip Horizontal and/or Flip Vertical in the Clone Panel then Alt-click to sample the catchlight and paint to clone it over the other side of the iris.
