Why More Megapixels Does Not Equal Better Pictures

Why More Megapixels Does Not Equal Better Pictures

At last check, digital point and shoot cameras were up to 12 megapixels. This begs the question, can you have too many pixels? Is there a point where more pixels will actually degrade the picture quality?

The answer is yes. Because point and shoot cameras have a fixed size to play with and the fact that consumers tend to like smaller cameras, this keeps the image sensor size small. A higher megapixel camera basically means more pixels crammed into a small space.

The result? Light spills more easily between those 12 million pixels compared to a proper digital SLR with the same number of pixels. This causes noise, a decrease in contrast and sensitivity, and ultimately a picture that is worse than one captured with a bigger sensor.

If you are interested in more technical details 6 megapixel is a good resource.
