Shooting with a long focal length lens has the effect of compressing the image to make elements appear a lot closer together than they really are. When shooting from the helicopter over LAX I was using a 100-400mm lens. The aircraft themselves were quite low to the ground, particularly those on short final to land. They weren’t a long way off the ground but the lens in use had the effect of making things look a lot closer than they really were. Some of the shots I got of the aircraft over parking lots or near the In’n’Out really make it look as if the jets were barely airborne. I like the extra drama this adds to the shots.
