If you recently upgraded from a compact camera to a DSLR, one of the first things you probably noticed was that focusing is done completely differently. Instead of simply pointing your camera at a subject and letting the camera figure out what to do, you now need to think about autofocus points, which often don’t seem as “intelligent” as the focus systems in point-and-shoot cameras. The truth is, autofocus points are extremely powerful and give you a great deal more freedom — you just need to know how to use them.
To get you started, here’s a great primer video by photographer Phil Steele. Over the course of 9 minutes, Steele steps through five fundamental tips for achieving fine focus and tack-sharp photos: ditching full auto, focus and recomposing, looking for edge contrasts, using manual pre-focusing, and making use of live view to aid in manual focusing.
