Okay, I was talking to some professional photographer. and his pictures are STUNNING. AMAZING. And he told me his camera is only 12.1 megapixels. He told me megapixels is only the size of a picture. What makes a picture look so real, so clean and clear, good quality and such? I always thought that's what megapixels was. Since it's not, what makes pictures quality so amazing? I'm really curious.
