Yes, personal photography with cell phones is "way up" but relevance, power and veracity is "way down." As the viewers screens are flooded with selfies and food pictures to fill the insatiable appetite for illusion the power of any picture in particular is lost in the sea of so-whatedness. Facebook users prowl their feed munching through prodigious quantities of images, not unlike how my dog wolfs down his kibble. It's what I've been referring to as the commodification of photographs. The quality, the meaning, the artistic messages, the influence - all fade as the quantity of imagery required to satisfy the billions of voracious media consumers soars with every passing day. How long does a viewer look at an image on FB when the feed coming in is like a torrent? So-called news sites just can't get the images fast enough to keep attention in their web sites. New photos means new eyeballs, if only for a split second. In the tech and advertising world (merging) it's called "consuming media" for a reason. Consumption doesn't mean appreciation or influence, it just means the eyeballs registered it. The fight for ACTION by those eyeballs means force feeding them with more. The consumers will not be able to keep up with the demand for more images, and AI will step in and fill the pipe.
I don't think most media consumers even care anymore how, or where, or when, or who, or what was involved in the individual image. There's no time to dwell on it before more images are pouring in. "Cute cat!" "WoW - what a burger." "What an ugly dress Jane is wearing." "OMG - look at that fool!"
Even on "serious" photography web sites you can see that the interest in the photographs is swamped by the interest in gears. You'll hundreds or thousands of wonderful photographs with barely a comment by anyone. There's just so many images the mind spins. Compared to the glory days of say, LIFE magazine, where images actually had heft, and value, and purpose, and usually veracity, and usually craft, today's images are just for quick immediate consumption.
So yes, we're seeing lots of photographs, just like we're seeing more and more hamburgers, but the nutrition is suffering badly. Quantity is up, meaningfulness is down.
