I have always sold prints in limited editions for the reasons given to you.
I have considered making my editions only 50 and tiered.. If you visit
Elizabeth Carmel's Fine Art site www.elizabethcarmel.com
, you'll see what I mean.
Have seen other photographer's do this and use it successfully. If you do this, may even want to make the limited edition even smaller.. something to think about..
Do you sign the print with the edition number or just the mat? Something I've struggled with for years..
I would be very interested in hearing any and all opinions on the subject.
