Everyone and their dog (a real-ish stat) has a mobile phone with 8-plus megapixels in their pocket right now, ready to shoot everything from the lunch on their plate to the election of a new Pope. And, this year, with smartphone sales expected to outnumber other cell phone sales for the first time ever (I know, we were shocked that this wasn't already the case, too), the best camera really will be the one you have with you — right in your pocket.
In 2013, smartphone sales are expected to surpass other cell phone sales for the first time ever. Combined with increased internet usage, this signifies a big boom for social photography. Tintype was the first "instant" photograph, and you had to sit perfectly still for 15 seconds (and wait another 10 minutes to get a print you could show off). With Google Glass, you'll be able to capture and share real-time footage of all the cool things you do on the move, like skydive or trip on the sidewalk.
Here is a little history on Mobile Photography throughout 2013. What where the trends, I think it's safe to say that Instagram was one of the bigger ones. And by sharing content through Facebook, whether it's about where we are staying or what we may be on the plate in front of us.
