I run an ecommerce service for wedding photographers and know a lot of other people in the industry. From where we sit, the consensus is that people are ordering less prints. All the growth we're seeing is from album/book sales and digital file sales. 5-10 years ago, a portrait photographer could charge a $100 sitting fee but still make $1,000+ on print sales. That is now hard/impossible. Everyone simply asks "Can I have the files on a disc?".
I can't see how it would be any different for the general consumer and their images. People get their utility from seeing the image on Facebook. My mom is 63 and she looks at our family pictures on FB every day.
Wont the generation that is accustomed to (and prefers) tangible prints be dead in 30 years?
