Film speed refers to the sensitivity of a given film emulsion to light and is represented by "ISO" followed by a number. Although digital cameras don't have actual film in them, the functionality is the same. Lower ISO numbers are less sensitive to light and have higher image resolution, while higher ISO numbers are more sensitive to light and have lower image resolution.
In this chapter, you'll find out which ISO setting is best for your jewelry photography depending on what you'd like to do with the final photo. You'll also see where to change the ISO setting on your camera.
