A digital photograph is a photo, produced with computer techniques, made up of hundreds of thousands or millions of tiny squares of colour. The technical name for these squares is picture – elements or pixels. The quality of any digital photo depends on the number of pixels per square centimeter – the more pixels, the better the photo, which is why you should always try to buy the best digital camera you can afford. 2. There are many reasons why people ought to consider changing from ordinary cameras to digital photography. You can change these pictures with your digital camera if you follow the instructions. You don’t waste time going to the shops for your films and photos, and you don’t have to spend money on films. There is also the advantage that digital photography is instant. You can view your pictures immediately – allowing you to decide which photos you want to keep and which you don’t. No more wondering if you should have taken a photo or not – with digital cameras you can take the picture first and decide later whether or not you want it. Of course, with digital technology you are able to change you picture so that it looks great anyway – that’s another huge plus when it comes to digital cameras. Lastly, and something we all ought to think about, is the fact that digital photography doesn’t use toxic chemicals that often end up in our rivers and lakes. There are a lot of strange shapes and sizes of digital cameras. However, the design doesn’t make any difference to the camera’s performance and you shouldn’t too influenced by this. Secondly, there is the cost. At the cheaper end of the market, there are the ‘point and shoot’ cameras. These cameras are fully automatic and anybody just starting digital photography should begin with one of these. They’re so simple that after only a couple of weeks, you should have learnt all you need to know about how to use the camera. For more money you can buy one of the megapixel cameras, which, as their name suggests, produce better quality photos by using more pixels. Some of these are a bit too complicated for everyday use. At the top end of the price scale are professional cameras and digital video cameras – very expensive and only necessary for the serious photographer.
