How does the camera store an image?

  • Direct computer connection:
    High-end studio cameras capture very high-resolution images that are often too large to fit on portable media. The solution is to cable the camera directly to a computer or external hard drive. The disadvantage is that the camera is not portable.
  • Internal memory:
    Some cameras have internal memory that either augments or replaces a removable memory card of some type. The internal memory of a camera, if present, is usually limited to a few photos worth of space.
  • Floppy disks:
    They can only hold 1.4MB of data, making them suitable for low-resolution cameras. They are also a very slow medium. Floppy disks are huge by digital camera standards, and the drive mechanisms required to process them are even larger.
  • Removable memory cards:
    These have no moving parts, so they can save an image in a fraction of a second. Small in size, they hold from 2MB to 2GB of data. Three examples are Compact Flash, SD and MemoryStick.
