Remember that the term "halftone"? A few years ago, newspapers published in all the pictures of half measures, and if one looks closely, one could see all the dots that make up the image.
The printing process could not print using a smooth gradation from black to white like a photograph does. So using the halftone process to make the image with small dots. Each point could be any variation from white to black. The dots in the dark image was black and the points that make up part of the image lighest had no ink at all.
Magazines have pictures much better than newspapers, because use much smaller, and so many more points. They also used different printing processes, inks and paper smooth.
Digital cameras have the same restrictions as newspapers presses – that can not burn smooth gradations of color or tone, because the camera sensor is also composed of points called "pixels."
"Pixel" is short for "picture element". But digital cameras have more pixels Journalists are so many points of the human eye normally can not see individual pixels when printed or displayed on a computer screen. A mega pixel is a million pixels.
So think of a single pixel as one of those points. The more the better … somehow! Having a mega pixels camera with a gazillion can be like having a car with 800 horse power in the Los Angeles traffic.
Just as an engine of 800 HP uses a large amount of gas, the cameras produce 12 million pixels create very large files. Too large to send by email without resizing it first. They also take much longer to downloaded from the camera and filled with a hard disk as a fire hose filled a bathtub.
If I want to take pictures and email them to Grandma, or put them in your website, or print for the family album camera 3 megapixels will do fine. Well, for 3 Megapixels is enough, so why why no one pays extra for more?
Suppose you take a picture of 3-megapixel camera basketball star making the game-winning shot.
Unless you are very close to the action, or if you have a great telephoto side, your hero will only fill a small part of the whole picture from your photo will contain around a third of the team sports arena.
So now you have a large picture of his hero … and the other players, and the 500 people in the stands! No problem because the camera comes with software so you can crop the image and expand its star so that he or she will fill most of the final image.
With this software that is really trying to get a close-up, without a telephoto lens. This is when you want lots of pixels! And here's why.
The image his hero was composed of, for example, 100,000 of its 3 million pixels in the original photo. Now, since I cut out most of all pixels, except those of his hero, who is asking the 100,000 pixels to fill the space previously occupied with 3 million pixels because the finished print will remain, by example, 4 x 6 inches.
Your software actually preform the necessary magic! Only now it still has 100,000 pixels, all you have tons of space between them.
Your software knows it looks bad, so calculated (guess!) What color dots belong to the empty spaces and gives you enough pixels to make any size picture you want.
However, only 100,000 are "real" pixels that the camera recorded. When printing includes too many "guess" pixels, you get a very poor expansion and a very bad impression, because all printers need "real" pixels they can get. Printers are much more demanding than a computer screen.
Therefore, a picture can look great on screen, but to be as bad when prints that are just throwing away.
The moral of this story is that if you go to expand a small portion of the image, or thinking about expanding the original picture (especially for print) that really want a camera that produces as many pixels as you can afford. If not, you can simply ignore the pixel in the race for the manufacturer of cameras and concentrate on finding one with other features that are important to you.
