Assignmnet 3: Seclection tool

Here I start with the original image. I'm assuming from "National Treasure". 

Next I apply a mask and use the magnetic laso tool to select the part of the image I want to keep.

 Then I use the paint bucket tool to fill in the selection black and make the area transparent

After repeating that process a few times on various pictures and copying and pasting I have the finished product below.
