photographic specifications

Please check out our Top Tutors section for a more detailed explanation of these terms.

  • Lens range shows optical zoom settings from wide-angle to tele as compared to conventional 35mm format. Digital zoom mostly just crops the image.
  • Focus can be auto or manual. Minimum focusing distance is stated here. Sometimes it is possible to get even closer in macro mode.
  • Metering can be matrix, center-weighted or spot metering. For the latter only a small circle in the center of the image is used to determine correct exposure.
  • Aperture and shutter can be set fully automatically to achieve correct exposure of an image, although some cameras allow manual control.
  • Exposure modes or "scene" modes are in-camera combinations of aperture and shutter speed for the best combination with predetermined image subjects.
  • White balance, which caters for different qualities of light in a scene, is mostly set automatically, but manual settings may cater for fluorescent or tungsten lighting.
  • flash units can be built in, pop up before use or a connection for an external flash may be present. (hot shoe, synch socket)
  • Viewfinders on digicams are mostly of the optical type. More advanced models may offer electronic or TTL (through the lens) viewfinders.
  • ISO rating is the sensitivity of the CCD sensor as compared to 35 mm film. ISO 100 is considered standard while ISO 400 or higher could be used in low light.
