In this tutorial I will show you guys some simple but efficient techniques that will help you make great movie posters.
First thing you need to do is to cut the soldier out of the background using the Pen Tool (P) and delete the background. Leave only the soldier visible and a transparent background. Name the layer Soldier.
Next I want you to make a new layer and place it under the Soldier layer.
Using the Rectangular Marquee Tool (M) make a selection and fill it with black as I did. Name the layer Ground.
