Thank you!
I don't think there is a way in LR - I did search for it! - But maybe our Koslowski can fix something?
I do understand that you have your routines. For me - without routines - the much simpler way is to ask a program do the work for me. I guess ACDSee is the best program, as you (and I) wish an uneven frame for the copyright sign.
http://www.picnik.com (free to use online) also does the trick very easily. But not as precise as made with ACDSee.
Yes, Bob Dylan has become a hit for me in more recent years. Here's a little younger artist with shadow made by Picnic. (No, I don't think the bow is a phallos symbol in this case )
