The digital zoom measurement on a digital camera, to put it bluntly,
is worthless under most shooting circumstances. Digital zoom is a
technology where the camera shoots the photo and then crops and
magnifies it to create an artificial close-up photo. This process
requires magnifying or removing individual pixels, which can cause image
quality degradation.
Most of the time you can perform functions equal to a digital zoom with photo-editing software on your computer after you shoot the photo. If you don't have time for or access to editing software, you can use digital zoom to shoot at a high resolution and then create an artificial close-up by removing pixels and cropping the photo down to a lower resolution that still meets your printing needs. Obviously, the usefulness of digital zoom is limited to certain circumstances.
