I had to make a quick trip across the country to D.C. recently. It was only a brief visit so I didn’t travel with any camera other than my phone. I originally thought the flight back was very early in the morning but it turned out I was mistaken and we took off once the sun had come up. We departed to the north from National which takes you towards all of the most famous views of the National Mall.
The flight path involves a turn away from the good view so you are fighting the appearance of the engine and the wing when trying to get a shot (and that doesn’t take account of the battle you have with the high quality windows of your average airliner. It is the best view you get of the area though so well worth a go. Shooting in RAW also helps to fix some of the issues you can get with a phone when the shooting opportunity is fleeting.
