Digital Photography

Digital photography, as opposed to film photography, uses electronic devices to record and capture the image as binary data. This facilitates storage and editing of the images on personal computers, and also the ability to show and delete unsuccessful images immediately on the camera or software itself. Digital cameras now outsell film cameras and include features that are not found in film cameras such as the ability to shoot video and record audio. Some other devices, such as mobile phones, now include digital photography features. The quality of a digital image is the sum of various factors, many of which are similar to film cameras. Pixel count (typically listed in megapixels, millions of pixels) is only one of the major factors, though it is the most heavily marketed. Pixel count metrics were created by the marketing organizations of digital camera manufacturers because consumers can use it to easily compare camera capabilities. It is not, however, the major factor in evaluating a digital camera. The processing system inside the camera that turns the raw data into a color-balanced and pleasing photograph is the most critical, which is why some 4+ megapixel cameras perform better than higher-end cameras.
