Photoshop Fun (While Learning)

I posted a couple of pictures of my wife, Rena, and I a couple of days ago. We took the pics on our recent trip to Saskatchewan. I have been playing around in the 30 day demo version of Photoshop CS3, trying to learn different and new things that will be useful if I actually ever do this as a business. I gave the extract filter a try on the picture of my wife and pulled her out of the picture and put her in with me. A little bit of scaling and it almost looks like we were both in the picture at the same time. A uselful tool to say the least.

I know for many these things are second nature in Photoshop, but it's all new for me and, even though a ripe old age of 53, it is invigorating learning all this new stuff. Now all I have to do is figure out how to retain it.
