What the Heck is a Megapixel? (ebook)

Now you can read the only guide ever published that answers this critical question.

Back in the fall of 2003, we ran an article in Computing Unplugged Magazine called "Your first digital camera." It was a simple piece, but it set off a firestorm of reader response that eventually resulted in the creation of Connected Photographer Magazine.

Sifting through the letters, the biggest theme was one of confusion. Many of you asked what camera should you buy and many others told me you were confused by all the specs. Rather than going through individual cameras and recommending them (they change each week), I'm going to help you understand what makes these cameras tick.

The place to start is megapixels. This is the one factor that seems like a good measure for choosing a digital camera, because it's an easy number to compare. The more megapixels, it seems, the better the camera. Right? Well, maybe.

This Solutions Guide will delve into megapixels and will help you really understand what the term means, and how megapixel-related choices can determine the quality of your images. There is some math, but it's simple and gentle. Read through the entire 20-page guide and you'll have a lot more knowledge that will directly result in better pictures and better prints.
