It's easy to see why digital cameras have grown in popularity. You still 'point and shoot' in the normal way, but there's no need to buy a film or to wait for it to be processed - you just download the images onto a computer, send direct to a printer or email them instantly to friends. And it's easy to get creative! Digital pictures can be edited so you can adjust colours, reduce 'red eye', crop the picture or add artistic effects. You can even use the images to create calendars, greeting cards and enlargements.
