Action or sports modes increase ISO and use a faster shutter speed to capture the action. Landscape modes use a small aperture to gain depth of field. Flash may be deactivated. Text mode increases in-camera sharpening to allow to photograph texts. Portrait mode widens the aperture to throw the background out of focus (see Bokeh). The camera may ...
In April 1983, ISO started to work to add photo quality graphics to text terminals. In the mid-1980s, both the CCITT (now ITU-T) and ISO had standardization groups for image coding: CCITT Study Group VIII (SG8) – Telematic Services and ISO TC97 SC2 WG8 – Coding of Audio and Picture Information .
ISO 690 is an ISO standard governing bibliographic references in different kinds of documents, including electronic documents. [ 1 ] [ 2 ] This international standard specifies the bibliographic elements that need to be included in references to published documents, and the order in which these elements should be stated.
Sv: Sensitivity value allows the photographer to control the ISO sensitivity, while aperture and shutter speed are calculated by the camera (this is a Pentax DSLR feature) M: Manual mode allows the photographer to control shutter speed, aperture and ISO independently. U: User mode (like program with preset)
To photograph outdoor night sports with an ISO 400–speed imaging medium, search Table 2 for "Night sports" (which has an EV of 9 for ISO 100), and add 2 to get EV 400 = 11. For lower ISO speed, decrease the exposure values (increase the exposures) by the number of exposure steps by which the speed is less than ISO 100.
Sunlit subject shot on a digital camera set to ISO 100, exposed at f/8 at 1/400 second which is the same exposure value as f/16 for 1/100 second, the recommended "sunny 16" exposure In photography, the sunny 16 rule (also known as the sunny f /16 rule ) is a method of estimating correct daylight exposures without a light meter .

Landscape photography (often shortened to landscape photos) shows the spaces within the world, sometimes vast and unending, but other times microscopic. Landscape photographs typically capture the presence of nature but can also focus on human-made features or disturbances of landscapes. Landscape photography is done for a variety of reasons.
