The Megapixel Myth
When it comes to taking digital photos, it’s the quality of the lens and the sensor that count, not just the number of pixels. A high resolution sensor with a low quality lens can only capture low quality pictures in high resolution. Also the image quality does not only depend on the number of sensor pixels but also on the quality of each pixel displayed. The displayed pixel size changes according to the physical size and properties of the display device.
