Characteristics of Digital Cameras
The body of the camera contains the image sensor which converts light rays to a digital signal. While the digital camera started with the
CCD (charged coupled device)
chips, current professional cameras replace the CCD chips with the
CMOS (complementary metal-oxide semiconductor)
chips (Musburger and Kindem 2009, p.279).
The digital camera is similar in nature to a polaroid camera because the image is
instantly available for viewing
Digital snaps are immediately
organised by date and displayed as thumbnail images
to be scanned visually. It needs
of sorting, editing and archiving a large number of pictures.
Once taken, the image can
to a web page or sent as a

History of digital cameras
The background: The history of the digital camera began with Eugene F. Lally who was trying to find how to capture digital images to take pictures of planets and stars in 1961. Willis Adcock, who was a employee of Texas Instruments, was awarded the patent for the first electronic photography system in 1972.
, who was a engineer of
the first digital still camera
as a prototype using a CCD (Charge Coupled Device) image sensor in
. The resolution was 10,000 pixels and it took 23 seconds to record the digital photograph
(the first commercial CCD camera).
(the first compact point-shoot autofocus camera).

The digital technology
is that a process is based on binary systems of "0"(off) and "1"(on) instead of a analogue system of a multiple continuous-value recording and processing signals (Musburger and Kindem 2009, p.33).
Digital still cameras
store captured photographs by image sensors as digital bits on a memory card or tiny hard drive instead of the film used in traditional cameras (KdmcBerkeley 2011).
There are two basic kinds of digital cameras:
(uses a system of mirrorrs to take the image through the lens and reflect it into the eyepiece) and
(looks through the separate hole at the top of the camera).

1. "I was there."
: People's behaviour has changed in public places, such as restaurants, concerts and sporting events.
(e.g. lots of arms holding cameras, flash at kick-off)
2. "We're taking more snaps."
: Today, It has enabled us to take a large number of photographs compared with the past.
3. "People are better photographers."
: We may have better photographs because we can take as many as we want with checking pictures on the display. In addition, we can print pictures at home on the printer.
4. "Citizen journalism"
: People have become to take a picture or a video using digital cameras and the internet when they observe dramatic events or phenomenons.
5. "We're all archivists."
: Many people take photos and put them on Facebook continuously. It could be an individual archive.
. Kodak DC290:
superior sensor resolution
and low price.
. Canon EOS 300D: the first digital SLR camera that
cost less than £830
. This marked the beginning of the fall in the price.
. Nikon D3: solved with one of the biggest problems -
. Apple iPhone: It was the most
Facebook and Twitter
are dominated by pictures taked and shared via the iPhone.
. Nikon D90: the first digital SLR camera to feature
to make professional quality films.
Photography has become simple so that people don't think a picture has any value. Also, professional photographers are being affected by online theft.
Our private lives could be infringed by those who want to see and hack our ordinary photos on the internet.
