I took a lot of photos of this particular sunset, this one really demonstrates that St. Louis-air orange-red. The pollution here is quite pronounced – you can see a dirty brown band hovering in the air over the area whenever you go up in an aircraft.
And, on an entirely personal note, this particular photoshoot was one of the very first where I can say that I photographed what I saw (or wanted to see) – in other words, I've sufficiently mastered the technicalities of photography to be able to capture what I want to capture. It's taken a while, it's been creeping up on me slowly but it seems to have arrived! 🙂
