Average seems to be around $15-$20 per roll, so you're looking at $20-$25 per roll of film total.
I said this before, but I don't think I could pay that much for processing even if I tried. Even on the high end, $5-10 is more accurate, and it can definitely be done for less than that.
Given that most professional photographers and high-quality photography enthusiasts like to take a dozen or more shots of the same event and pick the best one, 560 rolls is not a very big number, depending on the exact type of film it's either 6,700 or 123,000 final shots.
No. People don't shoot medium format film the same way they shoot digital. MF film shooters take their time and only take photos of things that are worth taking photos of, instead of mashing their machine gun 1523fps shutters in hope that they get lucky.
If you figure a couple hours wasted time vs the digital, and only pay yourself $10 an hour, that cuts in half the number of photographs you can get out of $14,000. It probably wouldn't last a pro a year.
Scanning doesn't take as long as weeding through your 4000 digital photos of the same thing, looking for the best one. I know, I've done it both ways.
An amatures could get a lifetime out of that much film, but what amature is using a friggin Hasselblad?
Actually, most Hasselblad users at this point probably are amateurs. The prices of the gear have gone down so much that these cameras are very affordable for hobbyists.
I'm not trying to make a "film is better than digital" argument here (both have their merits, and I believe film is the better choice for some applications), just want to stop the spread of misinformation. There seems to be a lot of it in here.
