Today we are going to key out the backgrounds by using the layer mask.
To begin with, add the photo and move it to a suitable position.
Select
the figure using Magic Wand tool or other selection tool.
Select
> Modify > feather, enter the value 2 then click "ok" to make the edge look
better.
Go
to the layer panel and click the button “Add Layer Mask” (the one highlighted)
Finish. You can further adjust the tone and color of the layer to better fit the background. (not shown in this tutorial)
