Say you have a picture of a man in a floral shirt. (I know, tacky, but just imagine for this question.)
I'm looking to remove the pattern (floral), while keeping the original highlights & shadows.
I would like to make this a new linked and/or mask layer so that I can insert a new pattern for the shirt, say plaid (not much better I know), and still have the realistic original shading/highlights.
The layer must be done in a way so that I can insert a regular jpg of the new fabric into the new layer as opposed to applying something from the pattern palate. I don't want to make the jpg a pattern and then do it that way because I will need to re-size and/or rotate the new fabric picture.
I've been trying this myself for a long time and can't figure it out.
