Be More Sensitive

The D5 offers ISO 3 million, but you can still shoot in the dark with an entry-level D-SLR.

As highlighted on the previous page, the smaller maximum aperture of a kit lens can restrict your choice of shutter speed. Nowhere is this more evident than when you’re shooting in low light, where you might not be able to achieve a shutter speed fast enough to reduce the effects of camera shake, let alone freeze the motion of a moving subject. Of course, this doesn’t mean you have to stop taking pictures: you can simply increase the ISO on the camera. The ISO amplifies the signal from the sensor; the higher you push it, the less light is required for a correct exposure, so you can use faster shutter speeds.
