DxO just (OK, a week ago but I found out today) released a stand-alone RAW converter that in essence consists of the demosaicing, denoising, and lens correction engine of the DxO PhotoLab software. Output from this converter is either JPG or DNG; you can also export to LR and PS directly. The user guide is available here: DxO PureRAW User Guide I just tried the converter on a few images. Here's is a comparison (strictly as FYI, I have no connection to DxO) of a shot taken with the D500 and 500PF lens, ISO 4000, processed with AdobeCameraRAW: Every image was cropped at the pixel level to 1500x1500px, then exported at 1000x1000 for upload to PN. Here's the same image after using Topaz Denoise AI: Here's what results using DxO PureRAW with HQ denoising: DxO PureRAW with PRIME denoising: DxO PureRAW with DeepPrime denoising: All the DxO PureRAW images above were exported as JPG, quality 100%. This one was processed with DeepPrime denoising and exported as DNG, then processed via AdobeCameraRAW and photoshop to create the JPG file: Here's another sequence, same camera an lens but ISO 12800: ACR/PS: Topaz Denoise AI applied to above image: And this one is DxO PureRAW with DeepPRIME denoising: I own but hardly ever use DxO PhotoLab 4 - simply because it is not convenient for me to import images into it first, do some processing, and then export them to finish processing in photoshop. This new standalone program makes the process a little more convenient. Just drag the images to be processed into the program window and let the program run (single image or batch) - there's no user input required (except at the beginning and end of the process). At the beginning, if the lens/camera is not yet saved in the program, one needs to download the lens correction module. Then select the denoising method as well as the output format. At the end, one needs to choose what to do with the results (review, export to an application). If one uses a camera/lens combination that DxO has no module for, then the program can't be used. EDIT: ignore the images below - I don't know why they are there and I can't delete them.
