I know it is that everyone thinks the more the better when it comes to your digital camera features. This theory is especially true in the case of mega pixels. I myself have been guilty of sizing up the number of mega pixels from camera to camera in the electronics store, but is this really necessary do we really need more pixels? To answer this, you must first know what you are going to do with the images. Before we address that issue, let's make sure we know what a megapixel is:A single pixel is the smallest unit of color that a camera's sensor has the ability to capture. The more pixels the sensor can hold results in a sharper image the camera duplicates. The technical term for a unit of "a million pixels" is a megapixel. Many cameras notate the abbreviated megapixel as "MP".Now then, how many of those pixels do we need? The first task in answering this question is to determine how we intend to use the images. We are mainly concerned about uses that require a high resolution digital photo. Putting a photo on the computer's screen requires a low resolution image, so any camera is sufficient, if this is our only intention. The most common need for high resolution photos is to print or develop pictures. Let us then focus on putting pictures on paper to answer our megapixel question.Now we need to decide on the largest print size we would like of our photo. Although pictures can be printed into poster-size images, the expense comes bigger also. Since most of us will not be using this size, we will consider poster prints a rarity. Since we have eliminated posters, next we find the three most common photo sizes to choose from. Online photo labs have specified that the following minimum resolutions are enough to generate high quality prints:4 x 6": 640 x 480 pixels (0.3 mega pixels) 5 x 7": 1024 x 768 pixels (0.8 mega pixels) 8 x 10": 1536 x 1024 pixels (1.6 mega pixels)I have found through my own trial and error that my 3 megapixel camera serves as the bare megapixel minimum that I would use for an 8 x 10" print. Mega pixels any lower will begin to show pixilation under close inspection. To prevent this, double the above megapixel recommendations when buying a camera. The example shows that if your goal is only for 4 x 6" prints, a 0.6 megapixel camera is plenty. Most digital cameras start a 2 mega pixels, which would be enough for quality prints up to 5 x 7".Once you know how many mega pixels are required for your photo needs, you can move on to mastering the other features of your camera and be another step closer to producing the highest quality images possible.Looking for the most extensive online digital photography course at a real bargain price?
