Depth of field is the effect where one portion of the image appears blurry and out-of-focus.

This mimics the photographic effect that's caused from lens being able to focus at only one distance at a time, making a picture containing objects at various distances from the camera have both blurry and sharp regions. Often includes [[bokeh]].

h4. Not to be confused with 

* [[blurry]], which is an umbrella term that also includes stylistic effects.
* [[foreshortening]], which refers to objects appearing larger and shorter when pointed to the viewer. An image can contain both, but not necessarily.
