I had the opportunity to listen to Jim Brandenburg speak when I was in college. Brandenburg is a photographer for the National Geographic and has produced some amazing work in his career. This may seem strange but the one thing I remember him saying was he convinced the powers that be to let him fly first-class because the windows were cleaner and clearer, the better to shoot the aerials that the Geographic is so fond of. As a 20-something college student I assumed that I would always fly first-class where ever I went, at the same time I did realize that I probably would never work for the Geographic….for one thing I don’t really like shooting landscapes or wildlife. All this to say that it’s worth keeping the windshield clean.
