Digital Cameras

Making a choice

Digital cameras come in all shapes, sizes and prices. £90 to £150 is enough for something pocket-sized with a decent 5x zoom range and a spacious 2.5 inch screen. Image quality is fine if you mostly view photos on a computer, but look out for optical stabilisation to minimise camera shake. If this is what you want you can choose from a wide range of Canon digital cameras, Nikon digital cameras and Olympus digital cameras.

If your budget is £150 to £300, you can go one of three ways. Some premium digital cameras are feature-packed gadgets with big touchscreens, GPS tagging, front-facing screens for self-portraits and more. Other digital cameras have big zooms that let you frame shots more creatively. A third kind offers superior image quality and advanced controls.

For a huge leap in image quality, budget at least £350 for a digital SLR camera. Their superior photos are mainly down to the size of the sensor, not how many megapixels it has but its physical proportions, which are around 10 times bigger than the ones in compact digital cameras. That means crisper details, a wider range of tones and less graininess

Megapixels

When you're choosing a digital camera, it's easy to spot the ones with big LCD screens and high megapixel ratings. This tells you little about a digital camera's image quality, though.

digital cameraIf you're upgrading from, say, an 8-megapixel digital camera, you'll want something that offers a significant improvement. However, while a 16-megapixel digital camera is tempting, quality is generally worse than with 10-megapixel digital cameras.


To understand why, think about the sensors in these digital cameras. They're about 10mm from corner to corner, but need to measure light at 16 million points. Each pixel is around 1/1,000th of a millimetre wide, and not a lot of light hits something that small. That makes it hard to measure the light accurately. The result is a grainy pattern as the camera tries to hide the noise.

Using fewer megapixels means each pixel on the sensor is a little bigger, capturing more light and measuring it more accurately. That's why enthusiast-oriented compact digital cameras use 10-megapixel sensors. This gives more than enough detail plus less noise than cheaper, higher-megapixel digital cameras. It also helps that these cameras' lenses let in more light. That's indicated by the aperture, such as f/2 or f/2.8, lower figures are brighter

Digital SLR

Digital SLR cameras are different. Because their sensors are so much bigger, they can afford to use higher megapixel ratings without being swamped with noise. SLRs have other advantages, too. They're designed for creative use wit
