WebNoise in photography is the arbitrary alteration of brightness and color in an image. The onset of this random variation generates what is called “noise”or “grain”, which is basically formed by irregular pixels misrepresenting the luminance and tonality of the photograph. These pixels are visible to the eye due to their large size. WebNoise is visible, but low for such a high ISO speed (thanks, no doubt, to software noise reduction). The noise in (A) is constant inside the sensor, i.e., before gamma encoding. When it is encoded with gamma = 1/2.2, …
