Also may mean "Perspective Control" for a lens that has the ability to shift to tilt to control linear perspective in an image. May also stand for personal computer in conjunction with digital photography. PDAF: Phase-detection autofocus. One of the mechanisms of automatic lens focusing. PF: Purple fringing. A form of chromatic aberration in ...
Due to recent advances in technology, duotones, tritones, and quadtones can be easily created using image manipulation programs. Duotone color mode in Adobe Photoshop computes the highlights and middle tones of a monochrome (grayscale or black-and-white) image in one color, and allows the user to choose any color as the second color.
When slower shutter-speeds, in excess of about half a second, are used on running water, the water in the photo will have a ghostly white appearance reminiscent of fog. This effect can be used in landscape photography. Zoom burst is a technique which entails the variation of the focal length of a zoom lens during a longer exposure. In the ...
In photography, reciprocity is the inverse relationship between the intensity and duration of light that determines the reaction of light-sensitive material. Within a normal exposure range for film stock, for example, the reciprocity law states that the film response will be determined by the total exposure, defined as intensity × time.
The f-number (relative aperture) determines the depth of field, and the shutter speed (exposure time) determines the amount of motion blur, as illustrated by the two images at the right (and at long exposure times, as a second-order effect, the light-sensitive medium may exhibit reciprocity failure, which is a change of light sensitivity ...
The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce.The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le Gras, France, in 1826, but Niépce's process was not sensitive enough to be practical for that application: a camera ...
Cam Ward sat out the second half of Miami's Pop-Tarts Bowl loss to Iowa State, with the Hurricanes falling 42-41. Social media had a lot to say:
Photography – process of making pictures by the action of recording light patterns, reflected or emitted from objects, on a photosensitive medium or an image sensor through a timed exposure. The process is done through mechanical , chemical , or electronic devices known as cameras .
