Digital Cameras

There have been many revolutionary inventions in the past decade, among them the amazing digital camera.  The digital camera has come a long way since the first models.  Now, almost every digital camera has at least five megapixels, as opposed to the two megapixel cameras that most people had only a few years ago.  There are even seven and ten megapixel cameras out there, but those are only necessary if you plan on blowing a picture up to a really large size.
