depth of field

[′depth əv ′fēld]
(optics)
The range of distances over which a camera gives satisfactory definition, when its lens is in the best focus for a certain specific distance.

depth of field

The area in an image from front to back that is in focus. The smaller the aperture (the larger the f-stop number), the more objects are in focus both near and distant. The wider the aperture (the smaller the f-stop number), elements in front of and behind the object in focus appear soft or blurry.

Set a Mood
In both moving and still pictures, depth of field (DOF) is widely used to call attention or create feelings. By focusing on one element in the image and leaving the rest blurry, the audience is drawn to that part of the frame. In addition, making surroundings softer or foggy can eliminate unwanted background objects that distract from the subject of the picture. See f-stop and focal length.


Quite a Difference
Changing the f-stop from f/29 (top) to f/4.5 (bottom) turns all the unwanted objects in the background into a blur.

To achieve this, the imaging system must possess a reasonably high biometric depth-of-field with noise reduction while optimizing light conditions to record images accurately over larger distances.
This is perfect for times when a photographer cannot shoot with their lens "wide open" to get the desired depth-of-field as they can now go back with FocalPoint 2 and apply the background blur that they would have originally achieved.
A PC-E lens' "tilt" control gives photographers additional creative control over depth-of-field.
developer of innovative camera accessories, including the ExpoDisc Digital White Balance Filter, today at Photokina (Hall 6, C035) announced the new ExpoAperture2 Depth-of-Field Guide, a pocket-sized circular calculator that enables photographers to quickly determine the depth-of-field for a given focal length, aperture size, and sensor or film format.
This results in a picture with greater depth-of-field, especially in scenes with both dark and light areas.
They can practice metering, bracketing, controlling depth-of-field, and working with both fixed and zoom lenses.
The exposure modes take into account virtually all shooting conditions and preferences are: Full Auto, Portrait, Landscape, Close-up, Sports, Night Portrait, Flash Off, Program AE, Shutter speed-priority AE, Aperture-priority AE, Manual and Auto Depth-of-Field AE.
8", filling the frame with dramatic detail and extremely shallow depth-of-field.
There are 12 shooting modes including ProgramAE, Shutter-priority AE, Aperture-priority AE, Auto Depth-of-Field AE and Manual as well as Full Auto, Portrait, Landscape, Close-up, Action, Night Scene and Flash Off.
Additional features of the new camera include a Night Scene mode which combines the perfect balance between natural light and flash for stunning portraits at sunset, a bright viewfinder, Metered Manual Mode for creative exposure flexibility, Depth-of-Field Preview, Partial Metering and AE Lock, a retractable built-in flash with Red-Eye Reduction and an In-Focus beeper for focus confirmation.
