Noise is the bane of digital photographers. The best way to deal with noise is to try and avoid it in the first place. But sometimes you’re faced with shooting in available darkness and the only way to get the shot is to crank up the ISO. In this tutorial we’ll take a look at various techniques for dealing with noise.
One way to avoid noise, even if you’re forced to shoot with a high ISO setting, is to make sure your shots are well exposed. Underexposed shots are much more likely to suffer from objectionable noise than properly exposed images. Consider the images in this example: Both were shot in low light at 3200 ISO, yet the one on the left is underexposed and the noise levels are dramatically higher. Good exposure matters.
