What is DSLR photography?

Digital single-lens reflex Photography (DSLR) is the mid- to high-end portion of digital photography. Cameras are commonly classified as point and shoot, advanced point and shoot (these add super zooms, video modes, alternate white balancing schemes, and more photography modes), and DSLR. DSLR cameras normally have interchangeable lenses, some of which are compatible with older film camera lenses. DSLR cameras usually have even more white balance options, exposure controls, shooting modes, etc. DSLR cameras often have larger image sensors, which can help greatly with low-light shooting and noise reduction. DSLRs usually have a burst mode which allows them to take 3 - 10 images in very rapid succession.

Now you've done it! Time for me to go buy one. My advanced point and shoot has great image quality and a fantastic zoom, lots of modes and things. But all of these would be improved with a DSLR.
