Selective focus images have very little depth of field. The technique is often used in situations where the background would be distracting if it was sharp.
-Use of selective focus. the contrast brightness of two images: one reflected from a fixed mirror, the other from a movable mirror. This system works on the theory that the sharpest images have the highest contrast.

A method of focusing using a wide aperture to ensure shallow depth of field and put emphasis on an individual area of a scene.
The selective focus technique in action
Note that it is in fact possible to achieve the selective focus effect using image editing programs. You can simply select one part of the photo, keep it sharp and then blur the rest.
Lastly... Selective Focus Works with ANY Nature Photography Selective-focus techniques, by the way, work on close-ups of any flowers, as well as other delicate plants and even insects.
Selective focus
This technique relies on the creative use of depth of field and a large aperture to direct the emphasis on the subject by deliberately placing surrounding elements out of focus.
Selective Focus Choosing a lens opening that produces a shallow depth of field. Usually this is used to isolate a subject by causing most other elements in the scene to be blurred.
Selective focusing.
Isolate the subject from potentially intrusive objects around it by increasing the aperture and reducing the depth of field.

SELECTIVE FOCUS - Employing shallow depth of field through the use of a wide aperture so that the subject is isolated from its surroundings because they are not in focus.
Selective Focus
Selective focus is a great tool that the photographer can use to direct the viewer's attention to a single point in the image.

Selective Focus - Choosing a lens opening that isolates a particular subject.
Shutter - A movable camera component that acts to control the length of time that light strikes the film.
Selective focusing - method of adjusting the lens aperture and shutter speed to give a depth of field that will limit image sharpness to a particular area of the image.
Using Selective Focus
One way to make something stand out is to use selective focus. When everything in a picture is equally sharp, the viewer tends to give equal attention to all parts of the scene.

[edit] Effect of lens aperture
For a given subject framing and camera position, the DOF is controlled by the lens aperture diameter, which is usually specified as the f-number, ...
To avoid clutter - use selective focus. As we noted before, one of the advantages of a wide aperture is that you can employ a narrow depth of field to toss the background out of focus.
If you've ever seen one of those really cool selective focus shots that wasn't done in Photoshop and wondered how to pull it off, chances are really good it was shot with a Lensbaby.
Wider apertures allow for 'selective focus', or the ability to isolate your subject within the frame. Conversely, if you stop the lens aperture down to its smallest openings, you increase the depth-of-field, or how much of the image is in focus.
Aperture controls the intensity of light entering the camera and also controls the depth of field, or selective focus that will present in the final image.
With non-SLR compact film cameras you can still experiment with selective focus technique but it will be a hit-and-miss situation.
When we photograph a flower close up - whether growing in a garden or peeking out of a vase - we often use selective focus.
John uses the sun and some classic lighting control techniques to get a modern "selective focus" food shot. There are no extra elements or rogue colors in his setup to derail the goal of simple elegance.
Your point and shoot cameras may be able to do selective focus. Simplify, with some degree for error, thru the viewfinder to minimize loss of clarity. Simplifying a photo is one of the main elements of composition and deserves an article in itself.
8, might result in nearby objects that are sharply focused while leaving more distant objects out of focus--a commonly used technique called selective focus--which could be very desirable for an outdoor portrait.

I've seen variations of this theme using selective focus on a moving element (perhaps a speeding car). Just do something, anything, to stay away from the typical path. Use the cliché as a springboard.

So I look for elements within the composition that will enhance the selective focus. I’ll look for an interesting foreground and background and then something mid-picture that I can then draw the viewer’s attention to.

Portraits look best when the background is either simple or out of focus; one technique is to use a large aperture and selective focus to cast the background into a soft blur.
" Inspired by Creed's assignments, the photographer developed a style that included the use of color to create mood, shooting from low angles, selective focus, blurry extreme close-ups, and in-camera double exposures.
"Slow" film - say, speeds below 100 ISO/ASA - can be used for slow shutter speeds - for deliberate blurring of motion, or large apertures to give small depths of field for selective focusing.
Notice how in some of the images, long depth of field emphasizes the sense of "flatness" in terms of perspective. Also notice how the short depth of field helps the viewer to place more attention on a single element by way of selective focus.
determine the extent to which your background will be in focus. Sometimes you want to record landscapes with vast depths; other times you want to isolate your subject against a clean out-of-focus background in a technique known as "selective focus." ...
to take the extra step of turning the camera sideways. Many photographers do not think to turn the camera sideways to take a vertical image. Vertical images are a photographer's way of attempted to imitate the brain's natural selective focus ability.
like when we first started photographing-our choices were befuddling then, too. We had no idea of what an Æ'-stop was or why we should choose a particular Æ'-stop and shutter speed combination. And what about depth of field versus selective focus?
The smaller the aperture (remember, higher numbers mean smaller openings) the greater the depth of field. F-22 is the highest aperture on most manual or semi-automatic cameras. See also Aperture, Selective Focus.
Another method would be to 'crop' the photo, so that the subject fills more of the frame. The subject can also be emphasized using an exposure control such as selective focus (depth of field).
