How to use the Green Screen technique in Photoshop.
Start with your photo either taken in front of a green screen
or a logo or shape with a green background.
And open your photo you are going to place it on.
Select the Green Screen Image using your Rectangular Marquee Tool and
copy and paste it to your photo.
You can move and size the green screen object any where on your photo.
To get rid of the green select your magic wand tool which is the fourth one down on your toolbox. Take the wand and put it over the green area this will highlight all the green.
After you have done that just simply hit the delete key on your keyboard this
will delete all the surrounding green in your picture.
And now you have the finished product enjoy.
