Image stabilisation

18When shooting in low light there are several options available to help keep ISO as low as possible. Sure, it will be higher than normal, but lower than it would otherwise be. The first is image stabilisation, sometimes called vibration reduction (VR), which is a technology found in some lenses or in the camera sensor. It basically counteracts small camera movements, and can allow you to shoot at slower shutter speeds than usual, which also means a lower ISO.
