What is a Digital Camera?

What is a Digital Camera?
By Ian Brookes

A digital camera is an electronic device used to capture and store photographs electronically instead of using photographic film like conventional cameras. It uses a digital sensor to capture the light instead of traditional film. The LCD on the back of a digital camera is your on screen guide to altering the settings before a shoot and reviewing the results afterwards.
The big advantage of digital cameras is that, unlike film, you can reuse the storage media over and over again at no extra cost.

Bearing this in mind you can quickly delete unwanted images and take more photographs as you go along. Also making photos is both inexpensive and fast because there is no film processing needed for obtaining prints.

The range of digital cameras is immense, and provides an equally large span of capabilities and functionalities. The main tip for using digital cameras is don't be afraid, read the manual and just experiment.

One of the main ways that manufacturers categorize their digital cameras is in terms of pixel count, ranging from low end consumer cameras around 3.1mp (mega pixels) up to 10mp or more in professional cameras. If you plan on printing 8 x 10-inch prints, a 5 megapixel digital camera is more than enough.

When you've had a digital camera for a long time, you'll learn enough to experiment with your digital photos online. Almost any digital camera is capable of taking pictures for display on the internet, or for sending across the internet as email and uploading to online galleries such as Webshots and Flickr.

One thing to be aware of is how many many pictures the camera can take with one set of batteries. Can the batteries be recharged, can I use normal AAs or does it need a lithium battery with its own charger?
