The results with the new Denoise feature compared to the manual noise reduction controls were rather mixed. But in my testing a value of around 20 for Amount was far superior to the results I achieved with the default value of 50. I recommend starting at a value of around 20 for Amount, fine-tuning based on the specific image you're working on, and the results you're seeing in the preview. I've also found that the default value of 50 for the Amount slider is far too aggressive, resulting in considerable loss of detail and texture in the image. This can be a minor disadvantage in terms of having an "extra" file to manage, but I don't consider this to be a major barrier. However, there are some drawbacks based on my testing.įirst, when you use the Denoise feature you will be creating a new Adobe DNG file rather than applying noise reduction to the existing raw capture. With a careful adjustment of the strength of the effect you can get a very good result with minimal effort. The new AI-based Denoise feature from Adobe is impressive, to be sure. Noise is reduced, but I also gained detail! (So, effectively ISO25600 in the shadows.) I used the new NR on the left, taking advantage of the less-noisy file to apply much more sharpening than I could on the old file. Here's an example of an ISO6400 shot pushed two stops. It's just our workflow is different than before. The end result of this new noise reduction feature is sharper images. And because there's very little noise remaining, I can sharpen the heck out of it. Afterwards, I sharpen the image as if it were a fresh photo. ![]() In the new LR regime, if I see noise I apply "AI" noise reduction. It was generally a balancing act where I tried to use as little masking as possible, and as much "Detail" setting as I could get away with, without creating a very noisy file. In the old LR regime, I would apply sharpening and NR simultaneously, attempting to create the sharpest image I could that didn't over-sharpen the noise in the image (for the intended output size). We're creating synthetic details "over the top" of noise, so while we might not exactly be sharpening the image, the new details we're creating respond to sharpening (even LR's default sharpening) far better than the noise grain they replaced. We're now increasing SNR not by simply reducing noise, but also by increasing "signal". ![]() I think we can't really separate noise reduction and sharpening with this kind of algorithm, because the new algorithm "creates" details.
