Digital Camera Basics …
  • Speed of shot – how long does it take from the time you press the shutter button for the camera to take the picture? How long until you can take another picture?
  • Storage – what type of storage? How much?
    • The type of memory card you use is dictated by which digital camera you buy. These physically different cards are -not- interchangeable.
    • Secure Digital (SD), CompactFlash (CF), SmartMedia (SM), Memory Stick (MS), MultiMediaCard (MMC) and xD-Picture Card (xD).

Digital Camera Basics …
  • Image format – what types of images will your camera take?
    • JPEG
    • TIFFs
  • Image quality – what will you be using your camera for?
    • Small prints (4x6) - 2 megapixel camera is sufficient (for PowerPoint, even less will do!).
    • Poster size prints - 5 megapixel or more
    • More megapixels does not always mean better pictures!
