I know how to mask, and I know how to make a pic partially transparant (in its entirety), but what I am trying to do is mask off a single puzzle piece (just a part of the pic), keep that in tact, and then make the rest of the pic transparant without deleating it persay. If I mask and then delete, the puzzle piece relative to the rest of the pic changes as the rest of the pic no longer exists. I want to keep the rest of the pic in place, only transparant. This way, the puzzle piece stays in place relative to the rest of the pic. How can I achieve this?
