There’s more than one way to expose an image correctly – it all depends on want you want from your final photo
■ The beauty of choosing the exposure is that it’s all down to just three settings: aperture, shutter speed and sensitivity (ISO in other words). The complexity, and what makes it interesting, comes from the other effects that each of these has on the image.
The ISO setting contributes no positive qualities to the final image, it simply needs to be as low as possible to avoid noise. However, aperture and shutter speed are elective; whether it’s selective or deep focus, frozen movement or slo-mo streaking, we need to factor these into the final choice of settings. Aperture-priority, shutter-priority and program modes are Nikon’s way of helping you to decide.
