I have an image of a stone wall and have created an aged poster in Photoshop
CS3 which I want to put on the wall. My problem is to get the effect of the
poster adhering to the contours of the wall. I have reduced the opacity of
the poster slightly and distorted it which sort of works but not as
realistic as it could be. Is a displacement map the way to go and if so
could someone advise me or point me in the direction of a tutorial please?
