JPEG

DCT compression later became the basis for JPEG image standard, which was introduced by the Joint Photographic Experts Group in 1992.
JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.

Mobile phone

The first cell phones with built-in digital cameras were produced in 2000 by Sharp and Samsung.
In addition to telephony, 2000s-era mobile phones support a variety of other services, such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games, and digital photography.

Digital photography uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film.

Social media

socialsocial media platformsocial media campaign
The camera phone helped popularize digital photography, along with the Internet, social media, and the JPEG image format.
JPEG was largely responsible for the proliferation of digital images and digital photos which lie at the heart of social media, and the MPEG standards did the same for digital video content on social media.

Photograph

Until the advent of such technology, photographs were made by exposing light sensitive photographic film and paper, which was processed in liquid chemical solutions to develop and stabilize the image.
The advent of the microcomputer and digital photography has led to the rise of digital prints.

Discrete cosine transform

DCTiDCTinverse discrete cosine transform
An important development in digital image compression technology was the discrete cosine transform (DCT), a lossy compression technique first proposed by Nasir Ahmed while he was working at the University of Texas in 1972.
The wide adoption of DCT compression standards led to the emergence and proliferation of digital media technologies, such as digital images, digital photos, digital video, streaming media, digital television, streaming television, video-on-demand (VOD), digital cinema, high-definition video (HD video), and high-definition television (HDTV).

Raw image format

Image sensors read the intensity of light, and digital memory devices store the digital image information as RGB color space or as raw data.
In digital photography, the raw file plays the role that photographic film plays in film photography.

Digital camera

Similarly, many camcorders can take still photographs, and store them on videotape or on flash memory cards with the same functionality as digital cameras.
It had a TFT liquid-crystal display (LCD) and stored up to 20 digital photos at 350,000-pixel resolution.

Bell Labs

Bell LaboratoriesBell Telephone LaboratoriesAT&T Bell Laboratories
The metal-oxide-semiconductor (MOS) process, invented by engineers Mohamed Atalla and Dawon Kahng at Bell Labs in 1959, led to the development of digital semiconductor image sensors, including the charge-coupled device (CCD) and later the CMOS sensor.

Digital printing

The captured images are digitized and stored as a computer file ready for further digital processing, viewing, electronic publishing, or digital printing.

Kodak

Eastman KodakEastman Kodak CompanyEastman Kodak Co.
The first self-contained (portable) digital camera was created later in 1975 by Steven Sasson of Eastman Kodak.
Kodak began to struggle financially in the late 1990s, as a result of the decline in sales of photographic film and its slowness in transitioning to digital photography, despite developing the first self-contained digital camera.

Webcam

Except for some linear array type of cameras at the highest-end and simple webcams at the lowest-end, a digital memory device (usually a memory card; floppy disks and CD-RWs are less common) is used for storing images, which may be transferred to a computer later.
Webcams can be used to take video clips and still pictures.

Digital image

Digital photographs are typically created solely by computer-based photoelectric and mechanical techniques, without wet bath chemical processing.
Its highly efficient DCT compression algorithm was largely responsible for the wide proliferation of digital images and digital photos, with several billion JPEG images produced every day as of 2015.

Digital photo frame

The increasing popularity of products such as digital photo frames and canvas prints is a direct result of the increasing popularity of digital photography.
A digital photo frame (also called a digital media frame) is a picture frame that displays digital photos without the need of a computer or printer.

Image sharing

Today photo sharing sites such as Flickr, Picasa, and PhotoBucket, as well as social Web sites, are used by millions of people to share their pictures.
Image sharing, or photo sharing, is the publishing or transfer of a user's digital photos online.

Today photo sharing sites such as Flickr, Picasa, and PhotoBucket, as well as social Web sites, are used by millions of people to share their pictures.
Picasa is a discontinued, cross-platform image organizer and image viewer for organizing and editing digital photos, integrated with a now defunct photo-sharing website, originally created by a company named Lifescape (which at that time was incubated by Idealab) in 2002.

Photosynth

Photosynth is a discontinued app and service from Microsoft Live Labs and the University of Washington that analyzes digital photographs and generates a three-dimensional model of the photos and a point cloud of a photographed object.

Image editing

Image editing encompasses the processes of altering images, whether they are digital photographs, traditional photo-chemical photographs, or illustrations.

Digital imaging

For example, the medium of visible light allows digital photography (including digital videography) with various kinds of digital cameras (including digital video cameras).

Dynamic range

DRdynamicdynamic and tonal range
Practical imaging systems both digital and film, have a limited "dynamic range": the range of luminosity that can be reproduced accurately.
The dynamic range of digital photography is comparable to the capabilities of photographic film and both are comparable to the capabilities of the human eye.

Chimping

Chimping is a colloquial term used in digital photography to describe the habit of checking every photo on the camera display (LCD) immediately after capture.

Bracketing

White balance bracketing, which is specific to digital photography, provides a way of dealing with mixed lighting by shooting several images with different white point settings, often ranging from bluish images to reddish images.

35 mm format

35 mm35mm35 mm film
Eight- to 24-megapixel images, found in modern digital SLRs, when combined with high-end lenses, can approximate the detail of film prints from 35 mm film based SLRs.
In digital photography, the format has come to be known as full frame, FF or FX, the latter invented as a trade mark of Nikon.
