There are several words and phrases used in digital photography. You may find it helpful to become familiar with some of them. Many of these words and phrases may be helpful if you are just beginning to use a digital camera. The following are many of the words and phrases used in digital photography:

  • Archival- The ability of a material to last many years. This may include printing papers and compact discs.
  • Aperture- A small, circular opening inside the lens that can change in diameter to control the amount of light reaching the camera's sensor as a picture is taken. Many cameras have an aperture priority mode that allows you to adjust the aperture to your own liking.
  • Application- A computer program, such as an image editor or image browser.
  • Buffer- Memory in the camera that stores digital photos before they are written to a memory card.
  • Burning- Selectively, darkening parts of a photo with an image editing program.
  • CCD- Charge Coupled Device: one of the two main types of image sensors used in digital cameras. When a picture is taken, the CCD is struck by light entering through the camera's lens. Each of the thousands or millions of tiny pixels that make up the CCD convert this light into electrons. The number of electrons, usually is described as the pixel's accumulated charge, this is measured, then converted to a digital value. This last step occurs outside the CCD, in a camera component called the analog-to-digital converter.
  • CD-R - CD-Recordable: a compact disc that holds either 650 or 700 MB of digital information, including digital photos. Creating one is often times called "burning" a CD.
  • CD-RW - CD-Rewritable. This is similar in all aspects to a CD-R, except that a CD-RW disc can be written and erased many times.
  • CMYK- Cyan, Magenta, Yellow, and Black these are the four colors in the ink sets of many photo-quality printers.
  • Compact Flash- This is a common type of memory card, about the size of a matchbook.
  • Contrast- The difference between the lightest and darkest areas in a photo. The greater the difference, the higher the contrast.
  • Download- The process of moving computer data from one location to another.
  • DPI- Dots Per Inch: A measurement of the resolution of a digital photo or digital device. The higher the number, the greater the resolution.
  • File- A computer document.
  • Grayscale- A photo made up of varying tones of black and white.
  • Highlights- The brightest parts of a photo.
  • Image browser- An application that enables you to view digital photos. Some browsers also allow you to rename files, convert photos from one file format to another, add test description and more.
  • Image resolution- The number of pixels in a digital photo is commonly called image resolution.
  • Inkjet- A printer that places ink on the paper by spraying droplets through tiny nozzles.
  • JPEG- A standard for compressing image data developed by the Joint Photographic Experts Group.
  • Media- Material that information is written to and stored on. Digital photography storage media includes Compact flash and Cds.
  • Megabyte (MB)- A measurement of data storage equal to 1024 kilobytes (KB).
  • Memory Stick- A memory card slightly smaller than a single stick of chewing gum.
  • NiMH- Nickel Metal-Hydride: A type of rechargeable battery that can be recharged several times. NiMH batteries provide sufficient power to run digital cameras.
  • Pixel- Picture Element: digital photographs are comprised of thousand of millions of pixels. They are the building blocks of a digital photo.
  • RAW- The RAW image format is the date as it comes directly off the CCD, with no in-camera processing is performed.
  • Thumbnail- A small version of a photo.
  • USB- Universal serial bus: a protocol for transferring data to and from digital devices.
