I'm not sure about that. Compare the automated film processing systems of back then to the automated pre- and post- processing performed by a digital camera set to green box mode and there's probably less (as a percentage) of that type of technical error now than back then. I think it's the sheer volume of images combined with the "free" nature of capturing and distributing digital images (IOW no incentive to take fewer shots or to cull out the junk) that lowers the average quality of the art.

, perhaps my most successful decade.
