Depth of Field in Photography

Deep Depth of Field, this results in an image that is reasonably sharp from the foreground to the background. Using a narrow aperture, such as f/11, is ideal to keep photographs of landscapes or groups in focus throughout.

A factor to consider when working with depth of field is your distance from the subject. The farther you are from the subject you are focusing on the greater the depth of field in your photograph. For example, if you stand in your front yard to take a photo of tree a block away, it has a deep depth of field with the tree, background, and foreground all in relatively sharp focus. If you stand in the same spot and take a picture of your dog that is standing just several feet
away, your dog is in focus, but that tree a block away is just a blur of color.
