Taken with my Nexus 5 on a plane trip from Charlotte to Seattle. Got lots of great pics from the road trip back through NorCal, SoCal, Arizona, Texas, New Orleans, etc., but I think this is the best cloud pic I got.
Edited only to get rid of that "through an airplane window" effect in Snapseed. The clouds were pretty wicked looking. We were around 30,000ft and it was almost 10pm, so you can see the ground covered in darkness, while the sun is still setting at that altitude. It was a really cool sight to see. The contrast was amazing.
Taken with my N5 from my kitchen window and cropped to residential eye-sores... freakish mid-june storm that dropped snow down to nearly 6K feet in the wasatch mountains. This was the sun setting on those mountains the next day.
Taken with a Nexus 4 - stock camera app + google+ auto-awesome.
My girlfriend and I were visiting Boston and coming back from Cambridge, we were walking down Charles River at sunset with the sailboats. I wanted to take a picture of the clouded sky with the sunset over the dome of MIT at the horizon with a few sailboats passing by.
