I would disagree, if you could pay £2 per picture and you went on 8 rides in the day, that is £16 they would make. With no printing or paper costs, the overheads would be minimal. Then add some electronic self service kiosk where somebody can simply swipe a wrist band or mobile phone with NFC chip, you could have people buying lots of photos digitally and video too with very little overheads.
There is so much technology out there which can do it, Port Aventure had it a good 10 years ago when you could get a picture emailed to yourself.
The test would be to see how many people want digital only and who wants real photos......
Plus will there be more profit in digital, I believe it is the way forward, plus most people will instantly upload to Facebook which is free advertising to millions of people.
