I’ve been a fairly serious photographer since about 1993, and even invested the requisite decade in perfecting black and white darkroom printing – just in time for the technology to vanish from commercial use.
Now, you can do amazing photographic things with a smart phone, and there are apps like Snapchat, Hipstamatic, and Prisma to do it. It used to be the thing to sneer at people who’d just grab an image in Photoshop and run some filters on it, but the filters are getting cool! And interesting! But most of all: fun. They’re taking advantage of the massive amount of computing we can carry around in our hand, to do face analysis and then apply the results.
