I have a nice photo that i took while i was away traveling and noticed that someones hand is on the right side of the photo and i would like to know how to take it out and replace it with the background that should be there. The handy (pun fully intended) thing is is that the background (what is behind/around the hand) is the sky with only a little bit of clouds and a few tall blades of grass around it. Also along the same lines would be any tips for doing fun stuff like cutting out peoples faces and putting them on other bodies etc...
The main goal is to fix the photo though.
BTW I have Photoshop CS, FW MX. I am more experienced with FW but would love to learn Photoshop!
