Part III: Appendixes > Updating the XSi/450D Firmware

A.3. Updating the XSi/450D Firmware

One of the greatest advantages of owning a digital camera such as the XSi/450D is that Canon often posts updates to the firmware (the internal instructions) for the camera to its Web site. New firmware releases can add improved functionality to existing features and, in some cases, fix reported problems with the camera.

New firmware along with ever-improving software keeps your camera and your ability to process images current as technology improves. To determine if you need to update firmware, you can compare the firmware version number installed on your XSi/450D to the latest release from Canon on their Web site.
