What Is a Kilobyte and How Is It Used in Photography?

The term ‘kilobyte’ or KB refers to a unit of measurement used to describe the size of a digital file. One kilobyte is comprised of 1,024 bytes of digital information. When a picture is captured on a digital camera the resulting file must be stored on the cameras memory; Depending of the resolution of the captured image, and the file format used to encode it, an image will take up a certain number of kilobytes on the cameras memory. Dividing the total size of a camera’s memory in kilobytes by the size in kilobytes of an image file will help you find out how many images you can store before running out of memory! A more commonly used measurement of file size is the megabyte, comprized of 1,024 Kilobytes.
