The decision to purchase a Canon Digital camera can sometimes be overwhelming when it is difficult to understand terms which are technical in nature. However if you wish to make the right choice in your purchase, you will have to know the meaning of these terms. This guide is written to help explain the meaning of what a pixel is and how its usage is related too to digital imaging.
The word pixel is the acronym for PICTURE ELEMENT. All Canon Digital cameras capture pictures in pixel format which is in essence small squares. Although digital images looks smooth like a photograph, it is actually made up of tiny squares patched together like mosaic tiles. Each pixel recognized by 3 numbers which represent the blue, red and green color channels. These numbers can range from 0 to 255. For example, you can represent a pixel using the number 30 in the red channel, 200 in the green channel and 75 in the blue channel. With these combinations, you can have possibly 16 million colors. It is with these numbers that allows a computer can recognize and display a pixel color and hue.
The use of pixel count is not only confined to digital imaging. All camera manufacturers nowadays also categorized their camera quality also according to the pixel count their camera can take. Depending on the type and model of the camera in question, most canon digital camera can take between 5 to 10 megapixels pictures. A megapixel is equivalent to a million pixels. What this mean is that a 5 megapixel camera can take an image with 5 million pixels in it. In terms of image printing quality, the more pixels a digital image has, the sharper the printed version of the image is.
When considering pixel counts as an indicator of picture quality, you also have to see the differences between "Effective Pixels" and "Total Pixels". When we talk about "Total Pixels", every pixel in an image is counted But in the final image, not all pixels are counted. The pixels at the edge of an image are normally disregarded. The term "Effective Pixels" is used to describe the remaining pixels after all the edge pixels are discounted.
With a 5 megapixels Canon Digital Camera, you will achieve excellent picture quality prints of 5" X 7" prints. 8" X 10" prints will be off decent quality. However, if you are going to print more of 8"X 10" size images; it is recommended that you purchase a 8 to 10 megapixels Canon Digital Camera. - 15437
