NIK EFEX Define – the Best Noise Reduction Software Available?<\/h1>\n\n\n\n
\n

Direct answer:<\/strong> NIK EFEX Define stands out because it gives you more control over what the software treats as noise, rather than just applying a blanket fix. In this workflow, you can sample a noisy area by hand, help the filter learn the difference between real image detail and unwanted grain, and then clean up texture introduced during sharpening, especially in clouds and other smooth areas.<\/p>\n<\/blockquote>\n\n\n\n

There are an awful lot of noise reduction tools about, and both Lightroom and Photoshop can handle the basics. The reason for using NIK EFEX Define here is simple: you get more say in what stays and what goes, which makes it a cracking fit for landscape work where detail matters.<\/p>\n\n\n\n

In the screenshot above, you can see a little box on the left. That area was selected with the mouse because it was noisy, then Define was told to treat it as noise. The point here is that the software can learn what is noise and what is actual image content, which gives you a more selective result than a one-size-fits-all pass.<\/p>\n\n\n\n

That extra control also helps after sharpening. Once you have run the NIK EFEX Pre Sharpener, you may end up with a bit of unwanted texture or noise, especially in clouds. You can then target those areas and let Define sort them out without clobbering the rest of the image.<\/p>\n\n\n\n
