A friend of mine has tried to denoise RAWs produced by using the in-camera multiple exposures mechanism of an EOS 5D MK III. Both HQ and Prime in DPL 2 are totally unable to denoise such images. Acceptable results are obtained with Lightroom and excellent results with the Imagenomic Noiseware plugin used in PS or Affinity Photo.
Is this actually expected ? Did I miss something or is there a problem with these particular files ? I can upload a few of them if needed.
Thanks in advance.
