Sports photography can be a little challenging especially for beginners and those who used to rely on a camera's automatic settings. Of course, in action sports photography, where people are moving fast or are making quick actions, it is important that you know how to take pictures to capture the action and to actually get a good picture that shows the action and not just a flat picture or something that is not blurry.
Aside from these factors, you also need to consider the equipment that you need in action sports photography. Of course, proper timing, correct ISO settings as well as a good location may not work right if you also lack the right equipment with you.
