What Is a Pixel and What Does It Mean When Talking About Photography?

When talking about digital images, or methods of displaying digital images a ‘pixel’ is the smallest component within a digital image. Pixel stands for ‘picture element’, they are the individual components that collectively recreate the image captured with your digital camera on a computer monitor. Image resolution is measured by the total number of pixels within an image; A VGA image for example has a resolution of 640×480 pixels  (total of 307200 pixels), the higher the number of pixels the higher the resolution of an image, or imaging device such as a computer monitor.
