I few weeks ago I had the opportunity to fly in a helicopter to photograph St. Louis’ riverfront. This is a pretty exciting thing to do if you get the chance. Be sure to have the doors off so there are no obstructions (and be sure you are well buckeled in). Shooting with a higher ISO and a low f stop keeps the shutter speed fast. This helps counter the extreme vibration and movement of the helicopter.
In this flight with Fostaire Helicopters we flew with 3 photographers, 2 on the left and 1 on the right, behind the pilot. We flew over Busch Stadium and then did a high pass in front of the Arch and then came back around again for a low pass. You can see the results on this page.
