Once the file is open, click the Device Noise Profile tab along the top. The first step of the process is to select your input image.
If you don’t, you can either let the software do its thing with default settings, or you can read the well written documentation to learn what the terms mean and how to adjust the settings. If you already know about luminance and chrominance, you can just get going with the software. The documentation was also organized so that you could get a lot of information, but only if you wanted to. The software was actually very easy to use and documentation on the web site was a lot more thorough than I’m used to. There is a free demo version that I used for this review. One option that I came upon was Neat Image ( It can be used as a standalone program or as a plugin for Photoshop. I decided to check out some noise reduction software. The ISO sensitivity level is labeled in each area of the image. For a good demonstration of noise, the image below is a composite image that I created from three separate images of a blue sky. Noise shows up as a sort of graininess that’s most noticeable in areas of a smooth color. Neat Image does an effective job reducing digital noise, it’s easy to use, and affordable for a range of users. Also, cameras that provide anti-shake using electronics (instead of an image stabilizing lens or a device to stabilize the sensor) will boost sensitivity in order to allow a quicker shutter speed. Many cameras increase the sensitivity when shooting in “Action” or “Night” modes. One of the biggest problems facing the quality of digital images is the “noise” that appears when images are taken at higher ISO sensitivities.
