I have taken two photographs:
- a hand holding a pen and writing on a white paper
- a sheet of paper with lines
Both photographs have been taken from the same camera angle (using a tripod), with the ruled paper placed in the same position as the white paper.
I now want to copy the two images into each other, making it appear as if the hand had written on the ruled paper. The end result should look something like this:
My photographs are completely sharp, so it is easy to cut out the pen, the hand, and the written text from the background of the white paper and overlay it on top of the ruled paper. The problem is the shadow of the pen and hand.
How do I need to set layer effects, or what else do I need to do, to make the white paper transparent and have the shadow appear on the ruled paper?
I'm working in Photoshop CS 5 on a Mac, if that matters.
I've tried the method described in the accepted answer to this related question, but this results in a light grey blur overlaying the lines. Using the technique in the linked answer, it seems as if the lines disappear in the shadow. Or in other words: the shadow darkens the paper, but not the light blue lines.
No, I cannot write on the ruled paper and photograph that. Don't ask why.
