Ripping Out Someone's Eyes Doesn't Have to Hurt.

Sometimes you take the perfect photo but the eyes aren't so perfect. Here is a way to replace eyes in Photoshop.
I just look for another image with a similar expression. Open both images in Photoshop. With the lasso, select around the good eyes. With the move tool drag the eyes to the other image. Lower the opacity of this layer to make it easy to position the eyes. Raise the opacity back to 100 percent. Holding the Alt key add a layer mask. Note that the eyes disappear. With the brush tool and white in the foreground color box select a soft edge brush and brush back the eyes.

Cheers,
