First time to this forum. Hope I am using it correctly.
I am trying to create the effect illustrated in the picture below. Although I want to slightly roll all 4 corners, with the emphasis on the left and right edges of the picture. The goal is to give the picture a slight cupped looked as if the left and right edges are curling up off the background.
Appreciate any help given.

Thank you in advance!
