# depth of field   
   
The size (or *depth*) around the [focal point](../../notes/camera/focal%20point.md) that the camera remains in focus—or, the distance between the closest and farthest objects in a photo that remain acceptably sharp. A shallow, narrow, or thin depth of field results in a faster growing blur from the focal point; while a deep, wide, or large depth of field reduces incremental blurring and produces a sharper image even for items that are out of focus.   
   
The point at which the subject of a picture is considered acceptably within focus is known as the [circle of confusion](https://en.m.wikipedia.org/wiki/Circle_of_confusion). Clearly defined intersections of cones of unfocused light that are captured in the final image are known as [bokeh](../../notes/camera/bokeh.md).   
   
The size of the [aperture](../../notes/camera/aperture.md) and overall lens construction determine the depth of field. A larger aperture results in a deeper depth of field, as more light is able to enter the lens, including more direct light from the surrounding objects. Conversely, a shallower depth of field receives less direct light from surrounding objects, making them blurrier, and increasing depth of field.
