DxO DeepPRIME XD vs Lightroom AI Denoise: from lifeafterphotoshop.com:
Lightroom’s new AI Denoise feature was the biggest news in Adobe’s April 2023 Lightroom update. Like so many other tools now appearing, it uses AI based denoising techniques directly on RAW image data to produce an enhanced RAW DNG file far superior to an image processed in the regular way.
You won’t notice a lot of difference at low-medium ISOs. This is for images for serious noise issues, and I have the perfect example from a bike meeting I went to a couple of weeks back. This photo was not actually shot at a high ISO, but I did do some very heavy shadow recovery which has generated a lot of noise. The photo was taken on a Canon EOS RP, which uses an older sensor that has a definite weakness in this area.
My regular Lightroom image is pretty well unusable. Lightroom tends to introduce a good deal of noise on its own, and when you combine that with this camera’s somewhat noisy deep shadow detail, it’s not going to go well. Worse, the Canon’s sensor is also introducing some blotchy magenta artefacts in this heavily recovered dark detail, and that’s not going be easy to fix, if it’s possible at all.
