NIK Define offers an auto noise detection option, which I used. I tried to find the lowest setting that did not reintroduce noise.įinally, I performed colour noise reduction. If the tool offers a setting to restore lost image detail (a side effect of noise reduction) I performed a similar operation. I then keep on making ever decreasing adjustments until I found the smallest setting that had reduced the noise. If it removed all the noise, I reduce the slider to 25% but if it had not removed all noise, I increased it to 75%. The tools being tested offer sliders that let you set the strength of the various noise reduction options.It can be a very hit and miss affair trying to find the best settings. With this image, it reduced the noise a little. I chose 1.5 pixels.įor images with low amounts of noise, this method can work.
