Over the years I have photographed many wedding exits. Some are as simple as bubbles and others are far more over the top, literally. For instance, in the image below the happy couple planned a helicopter getaway. Since the helicopter was in an empty field with no light what so ever, I placed a wireless flash in front of the helicopter about 30 feet away and shot with a telephoto lens to capture her joyful expression.
