As you begin to research, you may notice that many digital cameras have similar feature sets, but that doesn’t mean they offer equivalent performance. Read reviews (both online and in magazines). Ask friends, family, neighbors and co-workers about their choices. Before you start researching about any digital camera on internet or in shops Ask Five Questions Before Buying Digital Camera. It is not possible to to include all key considerations in one article,So today’s post is about how many megapixel you need?
What is a Megapixel ?
A megapixel (MP) is 1 million pixels, and is a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays. For example, a camera with an array of 2048×1536 sensor elements is commonly said to have "3.1 megapixels" (2048 × 1536 = 3,145,728). The neologism sensel is sometimes used to describe the elements of a digital camera’s sensor, since these are picture-detecting rather than picture-producing elements.
Printing and sharing photographs is lot easier with Digital cameras as compare to film cameras. Megapixels are important factor while choosing any digital camera but only more megapixels lead to better pictures. This is not the case.
Megapixels vs. Image Resolution
Any digital camera having 1.3 to 6.1 megapixels, bigger is considered as good digital camera. For high quality images megapixels matter up to an extend. Resolution is a measure of image sharpness based on the number of pixels that make up the image. More pixels produce sharper, more detailed images.
if you only need photos for a Web site,sharing on social networking, sending email or smaller prints (such as 3×5 or 4×6), you find great results and lower prices in the 1 to 2 megapixel class.
If you think that you may want to enlarge some of your images to 8×10 inches, consider a three-megapixel digital camera. Cameras in this category provide excellent-quality images.
Digital cameras with resolution higher then 5 or 6 are capable of producing professional quality images. Generally these type of digital cameras are designed for serious or professional photographers. Generally are not appropriate for beginning photographers.
