I sign my prints using Pentel Sunburst Metallic gel pens. My customers feel it is more a personal touch than having a digital signature. I also give them a note sized print with information about the print, things like it's title, date it was taken, location etc... Again, it just gives the customer a feeling of personal touch with the print, something they can't get from Walmart.
This is what I was looking for - thanks for taking the time to comment. Will definitely start doing the smaller print with information about date/time written on it, that sounds significantly more personalized to me.
