A Digital Cameras Mega Pixel Rating Is A The Measure Of The Resolution
Go to: Previous Article Next Article
A CCD provides an interesting advantage to the digital camera. It is possible to automatically adjust light sensitivity to improve contrast, shoot in dim light, or even take black and white, sepia or infrared and ultraviolet light pictures with the touch of a button.
With digital cameras, CCD is a grid of light sensitive points which capture the image for conversion into a digital image. The number of points on the CCD is measured in terms of "mega pixels." The mega pixel rating is a completely new bit of terminology and is unique to the digital camera.
If you have the money, a seven or eight megapixel digital camera, will get you a little bit extra detail for cropping or enlargements. Keep in mind, with a higher resolution comes a larger file size. You will need larger memory cards, and a more powerful computer if you choose to work on your pictures.
The next thing to consider is the type of digital camera. The compact point and shoot digital camera is not going to be good for shooting pictures of your children in sports. If you want to take pictures of a moving subject you'll need a digital camera that has an optical viewfinder.
Some cameras offer interpolated resolution to get bigger pictures from the same number of megapixels by using software algorithms to determine what color pixels to add, so the picture becomes bigger at the expense of clarity.
The digital zoom merely takes the original information and makes it bigger, and once again, clarity is sacrificed. Most serious photographers turn off digital zoom. Many digital cameras offer settings for such things as burst shooting mode, which is handy if you want to take pictures of moving subjects. The camera shoots a series of pictures without pause, then writes the files to memory.
