Wikipedia Overview
In digital photography, dark-frame subtraction is a way to reduce image noise in photographs shot with long exposure times, at high ISO sensitivity or at high temperatures. It takes advantage of two components of image noise that remain the same from one shot to the next, dark current and fixed-pattern noise. Noise from the image sensor include hot pixels, which light up more brightly than surrounding pixels.
