This film container denotes its speed as ISO 100/21°, including both arithmetic (100 ASA) and logarithmic (21 DIN) components. The second is often dropped, making (e.g.) "ISO 100" effectively equivalent to the older ASA speed. (As is common, the "100" in the film name alludes to its ISO rating.) Film speed is the measure of a photographic film ...
However, even if both techniques have inherent noise, it is widely appreciated that for color, digital photography has much less noise/grain than film at equivalent sensitivity, leading to an edge in image quality. [10] For black-and-white photography, grain takes a more positive role in image quality, and such comparisons are less valid.
Exif. Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) [5] is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones ), scanners and other systems handling image and sound files recorded by digital cameras.
The company also struggled with the transition from film to digital photography, although Kodak had developed the first self-contained digital camera. Attempts to diversify its chemical operations failed, and as a turnaround strategy in the 2000s, Kodak instead made an aggressive turn to digital photography and digital printing.
In mass communication, digital media is any communication media that operates in conjunction with various encoded machine-readable data formats. Digital content can be created, viewed, distributed, modified, listened to, and preserved on a digital electronic device, including digital data storage media (in contrast to analog electronic media ...
Digital photography spans a wide range of applications with a long history. Much of the technology originated in the space industry, where it pertains to highly customized, embedded systems combined with sophisticated remote telemetry. Any electronic image sensor can be digitized; this was achieved in 1951.
Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Dither is routinely used in processing of both digital audio and video data, and is often one of the last stages of mastering audio to a CD .
A CompactFlash (CF) card, one of many media types used to store digital photographs. Digital camera ( Panasonic Lumix DMC-TZ10) user interface, indicating the approximate count of remaining photos. Many camera phones and most stand alone digital cameras store image data in flash memory cards or other removable media.
