How Many Megapixels Do You Need?
The relationship between pixels and dpi seems to confuse many users. If you are confused, I highly recommend you read K.N. Pepper's DPI, PPI, Pixels - Facts and Fallacies before you continue.
When users are looking at digital cameras, they want to know the largest print they can print with good quality. I've put together a chart that gives you an idea of how many megapixels you need to have to print at various sizes. Since even a low megapixel camera can print smaller prints, the smallest size listed is 8" x 12" and the chart goes all the way to a 50" x 75" print.
While green is definitely good, the other colors aren't necessarily bad. Not only do you need to know the output size, but also the viewing distance. If the viewer is standing with two feet of the print, it is much different than if they are standing ten feet away from the print. Hopefully this chart will give you a better idea of how many megapixels you need for the projects at hand.
