Yesterday I ran into a client and her friend. She told me that she has hundreds of photos she's never printed and also never backed up! This gives me a pit in my stomach like you would not believe.
Before digital photography people would keep prints in a shoebox still in envelopes. Now we just leave them on the computer.
Please please print your photos- stick them in an album. Your kids will never say to you "hey let me look at that cd of pictures" or "let's open iPhoto and look at our vacation photos."
A print is archival. A hard drive is not.
Someone might say what a beautiful album. No one ever said nice shoebox.
