Digital cameras explained

Know your ISOs to your macros.

Rather than storing images on film, digital cameras save images to a memory card. The images can then be easily transfered onto your computer. You can them edit them using photo editing software, print them using a home printer or upload them to a photo sharing website.

Here are some of the key features of digital cameras.

Resolution

A digital image is made up of tiny pixels. The more pixels, the higher the quality of the image.

Memory

Memory cards have become increasingly larger and affordable. There are three popular types of memory cards for digital cameras: Compact Flash (CS), Secure Digital (SD) and Smart Media (SM).

Battery

Most cameras now come with a lithium rechargable battery and charger.

Scene modes

To give you a better picture, many digital cameras come with different pre-defined scenes such as sports, night time, landscape etc. If you select sports mode for example, the camera will adjust its settings to pick up moving objects and produce a finer picture.
