Hi,
I apply mine when I compress the final take in Cleaner -- I've never really thought about the best way to do it in AM through there must be a dozen different ways. It could be as simple as placing an image on a layer and constraining it to your camers so that it appears in the lower left hand corner. There is probably a better way but nothing really comes to mind. You might do a search of this forum.

thank you very much for you help.
