You may have noticed that the photos I've posted lately have unusual aspect ratios and sizes. This is because I have been lazy.
Usually, I upload photos from my camera or phone to my laptop, process them with Adobe Lightroom, and crop them to a pleasing 2:3 aspect ratio. Lately, though, I've just shot them through Google Hangouts from my phone. I have little understanding of Google's choices but they seem to be around the byte count and not around the dimensions.
Here, for example, is a shot of O'Hare Terminal 3 from this morning:
Google did that one at 1236 x 695, at 249 kB. The original is much larger (4 MB), but the same aspect ratio.
I may re-edit the photos later, after landing.
Update: here's the same photo after going through Lightroom:
