Introduction To Digital Photography

• Photography is a process of producing images of
  objects on photosensitive surfaces. It is divided
  into two types
• Film Photography
• Digital Photography

Digital Photography uses an electronic sensor to
record the image as a piece of electronic data
and is stored for later reproduction. The device
generally used for digital photography is a
Digital Camera. (Definition)
In the course of this presentation, I will
introduce the concept of - Digital Photography
through the medium of Digital Camera and mark out
its advantages over film photography.

Basic Features Of Digital Camera

• Audio/Video Recording
• Built-in and Removable Memory
• Electronic Flash
• Multi-Functionality
• and Connectivity

Distinguishing Components Of Digital Cameras

• SENSORS Digital Cameras consist of two main
  types of sensors -
• CMOS semiconductor sensor
• Charge-Coupled device (CCD)
• SLOTS and PORTS Digital Cameras usually consist
  of two types of ports and one slot
• USB (Universal Serial Bus) port
• Firewire port
• Memory card slot (For Additional Memory)
• LCD DISPLAY Digital Cameras are equipped with
  small LCD screens to aid the camera user for
  taking photographs/video recording with maximum
  ease. It also helps them in viewing the media
  captured previously.

File Types and Data Storage Formats

• Exchangeable image file format (Exif) is a set of
  file formats specified for use in Digital
  Cameras. The most common file formats are as
  follows
• JPEG (Joint Photographic Experts Group)
• TIFF (Tagged Image File Format)
• RAW (Best Quality of image captured)
• In addition to the internal memory that is
  provided in the digital cameras there are memory
  cards available in the market for additional
  storage purposes. The various cards available are
  
• MMC (Multi Media Card)
• SD (Secure Digital Card)
• XD (XD-Picture Card)
• Memory Stick
• CF (Compact Flash Card)
• (Various Memory cards)

Performance Metrics

• The quality of a digital image or video vary
  largely from camera to camera. This is due to the
  fact that the results are based on various
  factors, such as the -
• Pixel Count Usually more the number of pixels,
  better the quality and vice versa.
• Format of the captured media The RAW format
  gives the best capture result as opposed to JPEG
  and TIFF file formats.
• Sensor used to capture media The usage of either
  CMOS or CCD sensor makes a difference in the
  quality of media produced.
• Type of Lens Apart from the pixel count, the
  result
• of the image is based mainly on the type of lens
  used.
• Resolution, one of the key factors in
  determining the
• quality of the image is based on the type of
  lens used.

• Digital cameras of the same photographic features
  as of the film cameras, are more compact and
  slim and thereby it has a higher demand in the
  market. (Compact and Light)
