What are bits in photography?

Bit depth refers to the number of colors that can be displayed by a digital device. The higher the bit depth, the more colors used in the image and, consequently, the larger the file size. JPEG images are always recorded with 8-bit depth. This means the files can record 256 (28) levels of red, green and blue.
