Noise reduction software
Noise reduction software is designed to reduce visible noise when present in a digital photo. There are several programs available and each does a surprisingly effective job.
This tutorial is illustrated using the freeware version (Demo edition) of Neat Image.
Neat Image offers a variety of noise removal options for advanced users; however, it is set up so novices can easily and effectively use the program, too. Here are the basic steps:
- Open Neat Image; then click on the input image icon and navigate to and open your photo.
- Click the device noise profile tab. Select auto profile (or use a custom profile for your camera available at the Neat Image device noise profiles page). A section of your image is analyzed.
- If desired, select the noise filter settings tab to make adjustments.
- Select the output image tab and click apply. When the process is complete, save the output image.
Some full-featured image editing programs often have noise removal/despeckle filters, though they may not be as effective as stand alone noise removal software.
TopTip: When editing an image that contains noise, reduce the noise first before sharpening so as not to sharpen the noise.
