I tried this method and ran into serious problem with aligning the layers. Not really sure why this was... probably something happened in the scanning. Did you have similar problems?
The auto-align did a pretty good job, but not good enough so I went in and moved the layers one by one with the Difference blend mode on the top layer. I aligned the eyes in my portrait but I lost a lot of sharpness in the other parts of the photo. It shows in the bottom part of the attachments.
I am going to try to photograph this next...
