This has nothing to do with Fianl Fantasy but my wife recently asked me if there was someway I could render our faces together to see what our child may possibly look like...lol

I use a Mac and have photoshop. Could I just get pics of our faces and make em 50% opaque then layer on top of each other? Or is there a much better way to do it in photoshop? If so could someone basically walk me through the process? Or is there some program for Mac that i could d/l to do this? I'd like to be able to mess with the facial features to make it look either more feminin or masculine as well...
Thought I'd ask here cause obviously some of you are very skilled with graphic apps, whereas I suck.
