Photo Tip: Try varying your shots. The focal length you need depends on your distance from the burst and what you’re trying to capture. If you want a tight shot that shows detail, you will want to use a zoom lens that goes to at least 200mm. Keep in mind that changing focal length will require refocusing in most zoom lenses. Check for this attribute before the show begins, while it is still light.
