I am working on the given Image see the four boxes at the corners? I want to create a drop shadow effect on each one of them. so I have layer styles(drop shadow) for each one of them,but the problem is when I change the direction of shadow on one of them the others also change even though they are on a separate layer. How do I get a diffrent angle for the shadow for each one of them? Or is there any alternate way of acheiving the effect that the picture is inserted inside the cuts in the paper at the corners?
