A digital camera (or digicam) is a camera that encodes digital images and videos digitally and stores them for later reproduction. Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space.

A single-lens reflex (SLR) camera is a camera that typically uses a mirror and prism system (hence "reflex", from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured, contrary to viewfinder cameras where the image could be significantly different from what will be captured.

Check for the amount of memory that your camera has, the more memory for the price the better the camera. If you take a lot of pictures then you want something that has a good size memory, there are also SD cards available for extra memory if nothing is enough for you.
