Bring excitement and pumped up color to your subject's eyes by adding a Vibrance adjustment layer from the Adjust-ments panel (Window>Adjustments). Move the Saturation slider all the way to the left until it reads -100 and every-thing turns grayscale. In the Masks panel (Window>Masks), click the Invert button and the image returns to normal. Grab the Brush tool (B) and paint on the layer mask with white over the irises of the eyes turning them to grayscale. Now drag the Saturation up to 0 then increase the Vibrance until the irises dance.
