The purchase of a new Canon Camera can at times be trying as there are many technical terms which are foreign to a layperson. For a person to be able to make an informed choice, they will need to learn some of the terms that are commonly used. Terms like Pixels, DPI, PPI and white balance all are used to describe some of the qualities of a camera. This guide will seek to explain to you what a pixel is all about and how this term is used for rating a camera quality.
The word pixel actually stands for the term PICTURE ELEMENT. All digital pictures taken by the Canon Digital camera are composed of pixels. They are, in reality, tiny squares with different colors mosaic together like a giant jigsaw puzzle to form a digital image. Although at a glance, this is not evident until you enlarge the digital image significantly. Only then will you be able to see the little squares of different colors and hues. The colors and hue of each pixel is represented by 3 numbers, one number for the red, green and blue color channel. These numbers each, ranges from 0 to 255. Taken all together, there are 16 million possible color combinations that can be represented by these 3 numbers.
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.
You need also to consider whether when talking about pixels counts that you are referring to "Total Pixels" count or "Effective Pixels" count. Total Pixel count refers to the fact that all pixels that we see in a digital image are counted. Because in the final digital image, the pixels at the edge of an image are not used. As such the actual pixel count will be less. Effective Pixel count refers to the count only after all these edge pixels have been discounted.
Depending on the size of the pictures that you wanted to print, a 5 megapixels Canon camera, makes very good quality 5" X 7" printouts and decent 8" X 10" printouts. But if you are going to make 8" X 10" printouts most of the time, then a 8 megapixels or 10 megapixels Canon camera will be more ideal choice to purchase. - 16463
