Today’s DSLR photo tip continues with our series of tips covering functions on your camera that you are most likely not using. Let’s talk about back button focusing.
Have you ever tried to photograph a scene in low light conditions? Often the lens can’t find the focal point and will keep moving back and forth trying to find something to focus on. By the time it actually does focus on something, the shot has long since passed. Not to mention that the final focus isn’t always where you want it to be.
In other words, once you set up your camera for back button focusing, when you depress the shutter half way, it doesn’t affect the focus. You can focus with the back button and the focus point will stay the same no matter how many shots you take and even if you change the exposure settings.
Now, in that low light situation, you set the focus once and you don’t have to keep re-finding it. You can set your focus to have blurry shots if you want them, and pre-focusing on a certain spot is no problem.
Ever wondered what a Back Button Focus was? And how it could help you to improve the way you shoot in low light? Affecting the focus can setup your whole shot, depending on how many shots you wish to take. If you focus right, you won't have to keep re-focusing on your subject if your objective is multiple images.
