One of the key features used to sell digital cameras is the number of megapixels it has. Thanks to clever marketing from digital camera companies, most people assume that the more pixels a camera has the better the picture quality but, as you will find out, this isn’t the case.
When it comes to picture quality the size of the sensor tends to have greater significance than the number of pixels a digital camera has. The sensor is where the pixels are stored and the larger the sensor size the larger each pixel. This means that each pixel can collect more light and hold more information which, in the majority of cases, can help to increase picture quality. In fact fewer but bigger pixels is often better than more, smaller ones.
Will I be printing shots?
When deciding which camera to buy, the main questions you should ask yourself, when considering the number of pixels, is ‘Will you be printing shots?’ and, if so, how large will you be going to printing them? The main benefit of having more pixels is that bigger prints can be made, and selective crops may look better. For most people, ten megapixels is more enough to get a decent A4 print. If you’re only printing images at a normal size then anything over 4 or so megapixels will be suffice.
