If you want to capture your horse jumping as in the photo on the right, you will need to make sure you have a lot of light coming into the lens for it to capture the movement. You need good daylight, its doubtful if you are taking a horse jumping you will be close enough to use flash, however a fast shutter speed is important. Try to press the shutter speed just before you think you should as it takes time for the camera to take the picture, especially if it has to focus first. Otherwise you may miss the horse and rider all together!
