What is “resolution” and how does it affect digital photo image quality?
With digital camera picture quality, when you buy a digital camera you have to choose the number of megapixels. The megapixels is the size of the imaging chip, some people call that the resolution. What you need to know about megapixels is this, to make a 4×6 size print of photo quality you need 1 megapixel, to make a 5×7 print you need 2 megapixels, to make an 8×1 print you need 4 megapixels and that will give you true photo quality. So, when you’re buying a digital camera what you get when you buy more megapixels is the ability to make larger enlargements and the ability to crop the picture, it’s just that simple. Once again though, remember that lens quality is far more important to your overall picture quality than how many megapixels you have, as long as you make sure you are in the range of what you can do with your digital camera.
