Digital cameras
will compress the pictures you take so more can fit on your memory card.
The higher the compression you use, the lower the picture quality of the
image. You can change the level of compression depending upon how you are
using the photos. If you are taking pictures to e-mail, you may want to
use the highest level of compression, while you will probably want to use
the lowest level of compression when shooting to make prints. A good
general rule of thumb when shooting pictures you plan to make into prints
is to set your camera at the highest resolution setting and the lowest
compression setting.
This guide will
give you a very general idea of what to expect in terms of megapixels,
megabytes and media storage:

These ranges are only
estimates of how many images will fit onto the given size memory card.
This will vary depending on the compression setting of the camera, which
is usually adjustable. We recommend that you set your camera at the
highest resolution and lowest compression for the best digital camera
experience.
