To many people, the word focus has just one interpretation when applied to a photograph: Either the subject is in focus or it's blurry. But an artful photographer knows that there's more to focus than simply capturing a sharp image of a subject. You also need to consider depth of field, or the distance over which other objects in the scene appear sharply focused. This chapter explains how to manipulate both aspects of an image.

Some focusing options discussed in this chapter are specific to still photography; I cover video-related focusing settings in Chapter 7. Depth of field information, however, applies to both photos and videos.
