I shot a lot of aerial photographs this summer for a variety of clients...it's one of my favorite things to do on a nice day. I have to admit that there are times on every flight where I have to ask myself, "I'm getting PAID to do this?"
As fun as it might sound, aerial photography certainly has a myriad of challenges to achieve great images. The high cost of flying is one and you won't get any "mulligans" on your client's dime. You have to have the right gear and pick the right weather in which to spend your client's money.
An experienced pilot (preferably flying a very shiny, clean plane with no visible dents or scratches) is a must. You can't be afraid to ask the pilot to fly over the target at various altitudes or ask him to bank sharply to get just the right angle. The photo above of the new soccer field at Aquinas College is a result of good communication between myself and the pilot in fleeting light...it took a couple of passes before I felt I had "the shot."
