autofocus - How to precisely focus in self-portraiture with very wide aperture?



I've been trying to take some self-portraits, but I often have to struggle with the auto/manual focus. I don't miss by a lot, but I really want sharp focus in the eyes. I'm using a 50mm/1.8 around 2/2.2. What are some good techniques to get the camera properly focused when dealing with narrow DoFs?



Answer



Having taken quite a few self portraits lately, I'd recommend the following...



  • If you're trying for a shallow DoF to blur out the background, increase your aperture to 2.8-3.2 and move further from your background - it'll be it alot easier to nail the focus on your whole face.

  • If you have a face detection in Live Mode, try that.

  • Try setting just the center focus point on the camera and line up on that.

  • Make a mark where you're going to stand, pick an object you're always going to point your body towards. Pick another object you're going to point your head towards, and then look at the camera. Its probably going to take a few tries, so you want to be as consistent as possible.
