Chapter 9. Common Problems and Their Cures > Reducing Noise in Your Images

9.2. Reducing Noise in Your Images

Moving from the darkroom to digital can save you thousands of dollars in film and processing costs (not to mention a reduction in environmental degradation) but has added a new set of challenges to the art and business of photography. Perhaps foremost among the problems presented by digital photography is noise. Those pesky red, green, and blue (or light and dark) specks in an image can ruin a digital photo. Noise is generally most prominent in shadow areas and against dark colors in your images.

If your camera lets you select an ISO setting, you can help minimize digital noise in your photos by using a low ISO. Sometimes you do need to shoot the equivalent of faster film, such as at sporting events. However, when you have a choice, use a low ISO to minimize noise. And using a tripod can help, too!
