- As you start to gain more knowledge…of the technical details of autofocus,…especially as it relates to your particular camera,…it's time to start thinking about…the creative possibilities, and that primarily means…controlling both focus and depth of field for the scene…that you're photographing.…Here, I have an assortment of little buildings…and a car that I'm going to use as a test case…for establishing focus and depth of field in particular.…You'll recall that, when it comes to depth of field,…there's several factors that impact how much depth…of field, or how much of an area of focus…we're able to get for the scene that we're photographing.…
That includes the focal length of the lens.…A longer focal length will give us less depth of field,…or a narrower depth of field.…A wider-angle lens, or a shorter focal length,…will give us more depth of field.…And, of course, our position relative to the subject,…the distance at which we're focusing has a significant…impact on overall depth of field.…The closer we are to the subject, the closer we're focusing,…
Photographer and educator Tim Grey explores these questions and more in this exploration of focus and autofocus. And because sharpness isn't everything, Tim also details scenarios where blur can have more impact.
