The amount of depth of field produced by your digital camera might not be what you expect. You'll need to experiment.
Depth-of-field can be best described as the distance from the front to back in any image that is in reasonably sharp focus. Any parts of an image that are outside of this should be blur and are outside the depth-of-field. There are a few ways to control depth-of-field: use a small aperture, focus on a point further away from your camera or use a lens with a short focal length. Related Article Tags: , ,
Digital photos are built of many pixels. Each pixel has a unique value which represents its color. When you are looking at a digital photo your eyes and brain merge these pixels into one continuous digital photo. Each pixel has a color value that is one out of a finite number of possible colors - this number is known as color depth. Related Article Tags: , , , , , , , ,
Depth of field is defined as the range in which the photo is in focus. Achieving a specific depth of field is a useful photography technique used for example to achieve a blurry background effect. Film and digital cameras have different optical attributes as a result of using different sensor sizes. For that reason depth of field is also different in film and digital cameras.
