BACK BUTTON FOCUSSING
I had recently read in many articles that back button focusing is a method used by advanced photographers to get better focused images. Although I am far from an advanced photographer, I decided to explore the technique and find out for myself if it really is a lifesaver as many article claim it to be.
I am going to lay down my observations under three main heads:
1) What is back button focusing?
A DSLR camera when in autofocus mode, focuses on a subject when the shutter button is half pressed and on fully pressing the shutter button the image is recorded. Back Button Focusing assigns this focusing function to a button marked as AE/ AF L on the back of your camera instead
2) How is this better than regular half pressed shutter mechanism?
a)You can lock focus once and continue to click images of a stationary object with the shutter button. You no longer have to keep the shutter button half pressed to keep the subject in focus, which can be tiring.
For instance, you want to take candid shots of a stationary person and are waiting for the person to look up or smile. You would want the shutter to release fast to capture the expression at the right instance. Back button focusing allows you to do that easily.
The same reasons apply for using autofocus for a moving subject e.g., in sports or wild life photography. If something or someone comes in the frame with half pressed shutter method you might have to refocus. But with back button focusing your focus is locked on your chosen subject and you can repress the AE/ AF L button once the unwanted object/ person is removed from the frame.
No more refocusing every time you press the shutter button.
b)Focusing Once & Recomposing the shot is easier. Again you don't have to keep the shutter button half pressed while recomposing. Focus is locked on desired subject given that the distance between subject and camera remains same.
How this technique might help me?
Well my favorite subject - my son - has recently gained some control over his body and is constantly making sudden movements. Making taking pictures of him seem like wildlife or sports photography. The half pressed shutter button method often makes you miss the moment with the refocusing every time you press the shutter. A few tries with BBF did seem fruitful but it will take some getting used to.
