Two years into the AI denoise era, which tool is strongest as of June 2025? Thomas tested the built-in Adobe Lightroom/ACR denoise, DxO PureRAW and Topaz Photo AI across six high-noise scenarios — blue hour, indoor portrait, city night, wildlife, starry sky and drone telephoto.

Adobe first: in Lightroom or ACR, right-click the photo and choose Enhance to open the denoise panel (3:45 in the video).

Denoising and demosaicing offer several models — DeepPRIME uses deep learning only, while DeepPRIME XD2s adds AI on top and is the usual recommendation (4:56 in the video). 'Luminance' is the denoise strength; 'Enhance details' further sharpens hair and fine textures with AI. Better still, it applies lens optical corrections — sharpness, vignetting, chromatic aberration and distortion — cleaning up the RAW in one click (5:31 in the video).
