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
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.
If 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 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 with lots of hands-on controls, and their optical viewfinders give a detailed view that's better than any LCD screen. There's surprisingly little difference in image quality between a £400 and a £1,200 SLR, but pricier models are faster and have superior ergonomics, bigger viewfinders and extra scope to tweak every aspect of image quality.
Some digital cameras combine the image quality and performance of digital SLR cameras with the smaller dimensions and simpler controls of compact digital cameras. Most also use interchangeable lenses, so you can choose between a slim "pancake" lens, a bulkier zoom lens or buy both and swap between them. These digital cameras are relatively new and there's not a standardised name for them yet, examples include Sony NEX, Panasonic G-series, Olympus PEN and Samsung NX cameras.
Nearly all modern digital cameras use SDHC cards to bolster the paltry amount of built-in memory. If you buy a new digital camera, it's worth investing in an extra storage card at the same time. A spacious 4GB card only costs around £8 if you shop online, but much more on the high street or at airports.
Those who shoot a lot of video or use SLRs in raw mode should go for an 8GB or 16GB card. A fast SDHC card will avoid a performance bottleneck in fast digital cameras such as digital SLR cameras and look out for SDHC Class ratings, which appear as a number inside the letter C. Class 10 cards are the fastest and don't cost much more than slower cards, so it's definitely worth paying the extra if you've got a good camera.
That just leaves you to get your images off the card and onto your computer. Here, we'd highly recommend buying a card reader. These plug straight into a USB port on your computer and make it easier to transfer pictures, rather than scrabbling around trying to find the camera's USB cable.
Tripods If you're serious about your photography you should invest in a tripod. This will let you avoid shak
