I've noticed on a number of images posted here that the photographer digitally signed or printed the image's title on the lower border of the print (jpg). I've often wondered what software and techniques are used to do this. I use LR and PS, and as far as I know, LR does not allow one to watermark below the print. I guess I could manage this in PS, although I haven't tried. I would appreciate some guidance in how to do this.
