ISO is a camera setting that determines how sensitive the camera’s sensor is to light, with higher ISO numbers increasing sensitivity and brightness [1, 2]. While higher ISOs are useful in low-light situations or when faster shutter speeds are needed, they can also introduce noise or grain into the image, reducing its quality [1-3]. The goal is to use the lowest ISO possible to avoid noise and maintain image sharpness, but it is sometimes necessary to increase ISO to get a properly exposed image [4-6].
