Photographers, I challenge you to turn off your autofocus.
So much of our lives are now dictated by software, don’t let the focus algorithm take control of your photography style too.
Focus is perspective. The detail in your photos is a choice to make. When you submit to autofocus, you give up one of your liberties as a photographer. You are in fact letting the camera take your picture, instead of you.
You don’t let the camera select the aperture, ISO, or shutter speed. So why are you giving away the right to choose the focus?
The ability to decide how your image should look, what should be in focus and what should not, isn’t a function with a simple problem to solve. And yet, that is all the autofocus software is doing. Hundreds of software engineers together with product managers, photography designers, and consumer focus group experts created that feature. They have made a collaborative decision what it means to focus the image, and they pass that choice onto your picture taking experience, it is hardcoded into the camera autofocus. So when you take a picture and use autofocus, your focus is not perfect, you are simply outsourcing the style and detail in your photo to a long line of programmers, and photography experts, allowing them to choose how your photo should look.
Certainly if you have bad vision, no patience for finding a focus you like, a cell phone camera, a point and shoot without the ability to focus, or any of these other cases, then the feature is useful if not mandatory. But at least know why it is there and what you lose when you use it.
