Fixation is commonly achieved by treating the film or paper with a solution of thiosulfate salt. Popular salts are sodium thiosulfate—commonly called hypo—and ammonium thiosulfate—commonly used in modern rapid fixer formulae. [1]
Bleach bypass, also known as skip bleach or silver retention, is a chemical effect which entails either the partial or complete skipping of the bleaching function during the processing of a color film. By doing this, the silver is retained in the emulsion along with the color dyes. The result is a black-and-white image over a color image.
In time-lapse photography, the camera records images at a specific slow interval such as one frame every thirty seconds (1 ⁄ 30 fps). The shutter will be open for some portion of that time. In short exposure time-lapse the film is exposed to light for a normal exposure time over an abnormal frame interval.
[47] [48] It may be made by diluting household bleach as appropriate (normally 1 part bleach to 9 parts water). [49] Such solutions have been demonstrated to inactivate both C. difficile [47] and HPV. [50] "Weak chlorine solution" is a 0.05% solution of hypochlorite used for washing hands, but is normally prepared with calcium hypochlorite ...
The OSHA-allowable time-weighted average concentration over eight hours is 10 ppm, [30] almost 140 times higher; The OSHA highest allowable peak concentration (5-minute exposure for five minutes in 4 hours) is 200 ppm, [ 30 ] twice as high as the reported highest peak level (from the headspace of a bottle of a sample of bleach plus detergent).
Bleach activators are compounds that allow a lower washing temperature than would be required otherwise to achieve the full activity of bleaching agents in the wash liquor. Bleaching agents, usually peroxides, are usually sufficiently active only from 60 °C on. With bleach activators, this activity can already be achieved at lower temperatures.
It was created as Outstanding Cinematography for a Half-Hour Series, incorporating single and multi-camera programs, in 2008 alongside Outstanding Cinematography for a One-Hour Series. From 2011 to 2016, the awards were combined as Outstanding Cinematography for a Single-Camera Series. The categories were divided again between 2017 [1] and
Hand-held camera or hand-held shooting is a filmmaking and video production technique in which a camera is held in the camera operator's hands as opposed to being mounted on a tripod or other base. Hand-held cameras are used because they are conveniently sized for travel and because they allow greater freedom of motion during filming.
