0 IF U Buy a Camera by Checking Megapixels then YOU R WRONG, Quality not=to Megapixels

If you are buying a modern digital camera Checking Megapixels then YOU R WRONG, the number of megapixels it has should be the absolute last thing you consider. But because marketers have successfully fooled consumers into thinking more megapixels equal better picture quality, we’ll address megapixels first in our buying guide.

Then this is helpful in choosing best camera 

 A camera’s megapixel count simply reflects the number of pixels it can capture by the million. For example, a digital camera capable of 3.1 megapixels has a sensor that can capture an image of 2048 pixels wide by 1536 pixels tall, because 2048 times 1536 = 3,145,728 pixels.

 If you think about this for a second, you’ll quickly see how out of control the megapixel myth has gotten. A 3.1 megapixels digital camera shoots more pixels than is crisply displayed on a 60-inch, 1080p (1920 x 1080 = 2.1 megapixels) high definition television set showing a Blu-Ray movie. But most people use digital cameras to take 4 x 6 inch prints. Even a 0.3 megapixel digital camera does wonderfully at that.

  First of all, generally speaking, the more megapixels you have, the more visual noise is introduced into your image. That means that if your camera has more megapixels than its sensor is large enough to comfortably handle, your images will be less clear and crisp, not more so. Second, you’ll be wasting a lot of disk space on images that are larger than you’ll ever do anything with.

 Megapixel count is not an accurate reflection of a camera’s quality, end of story. Even the cheapest digital camera on the market will have enough megapixels to meet the needs of 99% of non-professional consumers. The camera in your cellphone probably has enough megapixels to comfortably blow up to a poster-sized print. Unless you need to do more than that, buy a digital camera with the least amount of megapixels as possible… and for reasons to be explained in our Sensors section, it’s best not to stray above 8 or 10 megapixels.

Summary:

Buy camera by checking type of lens used,

Technology used,

Don’t buy camera checking only megapixel’s – it only sucks your device memory space.
