Fireworks shots are always difficult because of getting the focus right against a totally dark background and timing the shot to coincide with the burst of the mortar shell. Fortunately, with a lot of fireworks displays, you have time to get the right shutter speed, focus point, and aperture. Using a tripod and remote release on a Nikon D-850, I was able to capture this image during a 4th of July display in the United States.
