Digital cameras are becoming more and more commonplace these days - they're so easy to find that you can even get them in key-ring size! Most people don't bother with standalone digital cameras now, preferring to just use their phones, but there are people who use more specialist cameras too.
There are a number of different types of digital cameras, and each on has it's own purpose. The Digital SLR is perhaps the 'standard' for high quality digital cameras these days, but there are other different types of digital cameras that are popular too. The compact, or point and shoot, is perfect for the average person who just wants to take a few photos, and the EVIL (Electronic Viewfinder Interchangeable Lens) is a good choice as well.
Many modern digital cameras have wi-fi attached to them, so they can be used to upload photos to Facebook, or upload videos to YouTube pretty easily.
Some have software that lets you edit images while you are using the camera; removing the need to upload the images to your computer to clean them up and process them.
There are a few things that you need to think about when you're looking at buying a digital camera. Make sure that the camera you buy has good battery life, and look at the number of megapixels it supports. Make sure, also, that you can shoot in RAW format. You don't want to shoot in JPG unless you have no choice, because JPG is too limiting - you would lose a lot of quality shooting like that, and you would probably find that you will not be able to get the shots printed out at high resolution.
Some cameras have a red-eye correction feature, which will make the flash 'flicker' a little to prevent the appearance of unsightly red eyes when you take photos of people. If your camera does not support this then you can use image editing applications to achieve a similar result.
Another useful feature is sports mode - which will shorten the shutter speed and also use some motion detection to try to get as clear a shot as possible, even when objects are moving very quickly. There are other tricks that you can use to get good shots as well, but having pre-programmed modes can save you a lot of time, stress and hassle when it comes to getting good shots.
