A macro photograph showing the defocused effect of a shallow depth of field on a tilted page of text This photo was taken with an aperture of f /22, creating a mostly in-focus background.
Blurring parts of the photo simulates the shallow depth of field normally encountered in close-up photography, making the scene seem much smaller than it actually is; the blurring can be done either optically when the photograph is taken, or by digital postprocessing.
Because depth of field is a characteristic of lens focal length (in addition to aperture and focus distance setting), it is easier to achieve a deep-focus look with a smaller imaging sensor or film gauge. For example, a 40mm lens will give a 30-degree horizontal angle of view in the Super35 format.
If every part of the image is within the depth of field, it is fairly easy to simulate the effect of shallow depth of field that could be achieved by using tilt or swing; [27] however, if the image has a finite depth of field, post-production cannot simulate the sharpness that could be achieved by using tilt or swing to maximize the region of ...
Series of images demonstrating a six-image focus bracket of a Tachinid fly. First two images illustrate typical DOF of a single image at f/10 while the third image is the composite of six images. Focus stacking (for extended depth of field) in bright field light microscopy. This example is of a diatom microfossil in diatomaceous earth. Three ...
DOF (Depth-of-field) bracketing comprises taking a series of pictures in stepped apertures , while maintaining the exposure, either by counter-shifting the shutter speed or, with digital cameras, adapting the ISO speed accordingly. In the first case, it will also change the amount of motion blur in the picture.
Increasingly, macro photography is accomplished using compact digital cameras and small-sensor bridge cameras, combined with a high powered zoom lens and (optionally) a close-up diopter lens added to the front of the camera lens. The deep depth of field of these cameras is an advantage for macro work.
Shallow depth of field panoramic stitching photographs are sometimes referred to as the Brenizer method, as he popularized it in recent years through his work. An image produced by this method is sometimes referred to as a bokeh panorama [ 3 ] (or the portmanteau bokehrama ) [ 4 ] in reference to the deliberate blurring style of bokeh photography.
