ABSTRACT
The digital photography era began when an electronic imaging sensor replaced film within the camera. The sensor's electronic signals are processed and sent to the camera's storage media such as a compact flash (CF) or secure digital (SD) card. Digital imaging resolution must be thoroughly understood by photographers to be able to effectively determine correct capturing of images with regards to their final usage. Prior to photographing anything, the photographer must make a decision as to how the images captured will be saved. Digital cameras have the ability to save images in various formats, and there are benefits and drawbacks to each one. Many digital cameras allow file saving in both the RAW and joint photographic experts group (JPEG) file formats simultaneously. Some camera systems have an imaging sensor that will contain a crop factor. The focal length multiplier is the mathematical relationship of the camera lens and its related crop factor.
