Back in 2008, I'd only had my digital camera for a year or so and had been playing with it. I set up one of the custom settings for night photography (which didn't work out right) and then proceeded to leave the camera set for that for some time. This lead to some remarkably blue photos. I did my best with the built in photo tool in Windows 10 to get it back to something close to true color. It's still too blue, but closer. Just looks like a cloudy overcast day. CalTrain and Amtrak's paint schemes didn't help.
