Nikon makes it even more convenient for you to shoot in changing light with Auto ISO.
This is a great convenience when you’re shooting under constantly changing lighting conditions, such as when you’re going from indoors to outside, or if the sky is partially cloudy or if you’re shooting in the shadows and then going into bright sunlight. Skip ahead to digital-and now, not only can you change the shutter speed and aperture with each image, but you can also change the ISO-on the fly-for each image you shoot. For photographers shooting film, the aperture and shutter speed might have changed from frame to frame, but ISO was always a constant-at least until you finished the rest of the roll of film (and at 24 or 36 exposures that was usually a ways away). A photographic exposure is dependent upon three variables: aperture, shutter speed and ISO.
