| The digital cameras megapixels madness is very similar to the personal computer MHz madness back in the 90s. A megapixel simple put is one million pixels recorded by your digital cameras image sensor which is the equivalent of the light sensitive film in film cameras. Today while you go shopping for feature-rich digital cameras physically or on the Internet often you will find manufacturers running out of their ways telling this camera takes great pictures. And if youre just about to get a brand new digital camera youll save yourself a lot of hard earned dough by making the right choice about how many megapixels you really need. First youll save money on the camera itself, since the price of a digital camera is directly related to the number of megapixels it can capture. There is a direct relationship between the size of the CCD the digital camera uses the number of megapixels it supports and the size of each pixel. No because the biggest photo that Ill print will be A4 or 10x8 and a 5 megapixel camera is more than capable of producing a quality photo at that size. If you will be shooting pictures that will be printed at a print house, such as for brochures, postcards, etc, then you will need at least a 5 megapixel camera if not higher. Let us go one step further on behalf of the average consumer and say you will not need more than ten megapixels, unless you are a pro and like to blow up your pictures really big. Heres how to determine how many megapixels youll need depending upon the type of photos you will be taking and what you intend to do with them. Expert photographers and reviewers have time and again said that as much as they would like to give a one word answer to one asking how many megapixels would be fine for him/her this one happens to be of the trickiest questions in digital photography. It should be noted that there is no technical limit to megapixels as there are professional digital cameras that support twenty to thirty megapixels. Digital cameras with resolutions of 10 to 13 megapixels are well in the quality range of good 120mm professional cameras. Because today there are many cameras that offer the same number of megapixels. At the end of the day the more megapixels your camera can do the more options you have. Simply put megapixels refer to how many millions of pixels make up the images a particular camera takes. The term megapixels are usually used to describe the output size of digital camera images. Megapixel is a technical term for million pixels where a single pixel is the smallest unit of colour that a cameras sensor is able to capture. While pixel size is certainly the #1 priority in my book if your overall resolution is not in the same ballpark as your competitors, your imagers benefits become less of a benefit. There are many reasons to care about the pixel size as it plays an important role in the overall quality of your digital photos. Now that we know the minimum megapixel requirements for our needs we are free to focus on other important features of the camera such as lens quality, colour reproduction, optical zoom, body size, etc. Likewise, the size of an image needs to be expressed as, say, six by six inches at 300dpi. I suggest that almost anybody will be happy with a camera with a six megapixel resolution. Lets assume, however that you do have a computer, and you do want to purchase a digital camera.
