Supplement: Noise-reduction Software Image Examples

By Diane Berkenfeld

Sometimes though, you have to push the ISO capability of the camera or shoot with less light than you’d like. That’s where noise reduction software comes in. Adobe Photoshop has a noise reduction feature, but it's not as robust as the plug-ins and standalone applications whose primary function is to reduce noise. Most raw conversion software also incorporates noise reduction, which works well for raw file shooters.

This Keep Out sign was taken in 2003 at Ellis Island with the Kodak DCS Pro 14n DSLR. Anyone who ever shot with that camera knows that at its minimum ISO, it produced decent images, but go above ISO 400 and the noise was unbearable. The exposure is 1/180 second at f/6.7, ISO 400. Exposure was adjusted after noise-reduction application usine curves. ©Diane Berkenfeld
