...or does the horizon appear to be bowed up in the middle, almost like a barrel distortion over-correction? I took a few shots earlier in the session that looked normal, so I know it can't be a hardware defect. I then swung around when I noticed a rainbow behind me and got a few shots of that. It was when I swung back around (I have the phone on a tripod) when I noticed it in this shot and about a dozen more.
