FEATURED WEB TUTORIAL: EDITING
 

Reducing Low-Light Noise in Digital Images

Published by:  Photo.net
Tutorial Preview:

This article is about a method of reducing noise in images taken with digital cameras - especially long exposure and/or high ISO images taken with digital SLRs. The simplified workflow presented here is derived from more advanced techniques of noise reduction (known as calibration) that are used in scientific and technical imaging. Because of limitations in the software tools commonly available to mainstream photographers, and because of limitations to the image-making equipment, there are several significant differences between the technique described here and a proper calibration of a scientific image. Still, the method here can result in significant aesthetic improvement to many digital images that suffer from noise.
