Another way noise is corrected is by taking one dark exposure that is as long as the original exposure, then creating a mask that is used to reduce or remove the noise by modifying the color value produced by the noise. This process is known as dark frame reduction. A modification of this process uses short-interval exposures that add up to the total time of a long exposure.

A transistor, the basic unit of a digital computer, is either in the on position or the off position. Therefore, a numbering system that relies on the root number 2 works perfectly. This basic building block of digital computing and digital images is known as a bit. One bit signifies the number 1 or 0, which indicates on or off for a transistor. When you put eight bits together, you create a byte. A byte is equivalent to 2 to the 8th power (28 = 256). One megabyte is 1,024 bytes, and one gigabyte is 1,024 megabytes.
