Instructions

1

Open the two photos you want to use in Photoshop -- the photo of the person you want to remove, and the photo you want to place them into.
2

Click on the photo of the person so that it is the active window.
3

Select the lasso tool from the tool menu. It looks like a rope.
4

Carefully trace the outline of the person. When you release the mouse, they will be selected.
5

Go to the "Select" menu and click on "Adjustments."
6

Click on "Modify" and "Contract." Contract the selection by 1 pixel.
7

Return to the "Modify" menu and click "Feather." Feather by at least 5 pixels to smooth the selection edge.
8

Press Ctrl+C on the keyboard to copy the selection.
9

Click on the photo you want to paste the person into so it becomes the active window.
10

Press Ctrl+V to paste the person in. Photoshop automatically places pasted objects in a new layer, so from there you can move the person's photo where you like.
