On long exposures the light enters the digicam, hits the sensor then small amounts of it are bounced returned onto the back cease of the lens to then be reflected returned onto the sensor, creating shade and noise patterns and textures. With excessive iso settings the equal principle applies except it’s miles magnified into a shorter time by means of the high sensitivity of the sensor.
