Slang for a small or compact camera that is easy to use because the essential functions are automated. Popular, but with limitations compared with more advanced cameras such as DSLR cameras with larger image sensors. PPI: PixelsPerInch. The number of pixels or picture elements contained in one linear inch in a digitally stored image. PS, PSE
For digital photo cameras ("digital still cameras"), an exposure index (EI) rating—commonly called ISO setting—is specified by the manufacturer such that the sRGB image files produced by the camera will have a lightness similar to what would be obtained with film of the same EI rating at the same exposure. The usual design is that the ...
For example, as of 2008, Nikon cameras allow one to set the maximum and minimum ISO sensitivities, and slowest shutter speed that will be used in automatic modes, [4] while Canon cameras will select within the fixed range of ISO 400–ISO 800 in Auto ISO mode. In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at ...
All cameras will have roughly the same ISO setting for a given scene at the same shutter speed and the same f-number – resulting in substantially less noise with the full frame camera. Conversely, if all cameras were using lenses with the same aperture diameter, the ISO settings would be different across the cameras, but the noise levels ...
Because 'International Organization for Standardization' would have different acronyms in different languages (IOS in English, OIN in French), our founders decided to give it the short form ISO. ISO is derived from the Greek word isos (ίσος, meaning "equal"). Whatever the country, whatever the language, the short form of our name is always ...
The CAS code shows this is (top row) ISO 125 film, (bottom row) 24 exposures, +3/−1 f-stop exposure tolerance. The DX barcode reads 017563, showing DX number 109-12, 24 exposures. DX ( D igital inde X ) encoding is a standard for marking 35 mm and APS photographic film and film cartridges, originally introduced by Kodak in 1983.
