Join Tim Grey for an in-depth discussion in this video Setting and choosing focus points, part of Learning Photography: Autofocus.
- Autofocus can, of course, be tremendously…helpful when you're capturing an image, but only if…that autofocus is actually focusing on the right place,…in the area that you want the image to be focused on.…By default, in general, you'll find that most cameras…are going to focus at the center of the frame.…In some cases the autofocus might be using an area,…looking at the overall scene, finding the closest subject…to the lens, et cetera, so there will be some variability…in terms of specifically what is being focused on,…but fortunately, you can generally…change where that focus point is.…
