Yes, I think most Topaz models try to invent details while some other AI programs like DXO tries to not invent just clean up. “What is particularly noticeable are of course the colors, where Denoise has problems, and details like fonts.” Where one can compare the two tools is features and workflow advantages and limitations. Results will vary and its not about which tool but results on the end. Depending on the skill of the user, particular image etc. But if you have supported RAW files DXO deep prime + Topaz Sharpen, not de noise produces by far the best overall results. Topaz is only option, DXO is not even available. Which means that if you are Fuji shooter or working on unsupported RAW file sor just scanned files etc. Where Topaz can do no wrong.Īnother benefit of Topaz is that works with JPEG or TIFF’s and not only supported RAW files like DXO. This leads to confirmation bias, quite present among few people on this forum. Doing a random set and forget comparison like this on a random file will produce all kinds of results and one can choose to use which ever one thinks they like better as a software. In other words its the combination or tools and workflow that produces best results. However, the best workflow I found is DXO for everything regarding RAW conversion, including de noising, and than applying sharpening to TIFF or JPEG using Sharpen AI from Topaz. Secondly, build into the De-noise from topaz are sliders for sharpening etc. So this means you have to use Topaz de noise at the end on a TIFF or JPEG, adding extra step, and limiting some of the features like shadow recovery. There is no correction of lens distortions and color rendition is something one cannot adjust and when you export DNG file its not fully readable as original RAW by other programs. Speaking of RAW de noising, its another problem since Topaz is not really designed for it. to some Extent this can be mitigated by first applying color noise removal in programs such as Lightroom or Capture one and than applying only luminance noise reduction in Topaz, but at the expense of not being able to apply the de noising in RAW. This is where DeepPrime does amazing job and topaz does not. For example, Topaz has serious problems with lot of color noise when camera sensor is stretched to the limit. The user input and ability to adjust is the critical component and this is where most of these types of tests fail, because they don’t rely much on ability to adjust the image by skilled user.Īlso every image is going to be context sensitive. This is like testing colors rendition in RAW files. apply it to the EM1.2_ISOxxxxx_0EV_EFC.JPG file and post it in this thread.I think you guys are doing flawed comparisons. In case you find much better settings feel free to e.g. I really struggled to find the best settings for Topaz Denoise, so I sticked with auto. You can find the all the files in the Dropbox. ![]() There is also a run with DXO_HQ.jpg file, so lightness and colors match here, but Topaz has to deal with the (good and bad) changes introduces by DXO ![]() ![]() Therefore the lightness and color of the Topaz file is different from the rest, but should be good enough to compare the noise reduction. for ISO25600 it looks like this:ĮM1.2_ISO25600_0EV_EFC.JPG = Out of camera JPGĮM1.2_ISO25600_0EV_EFC_DXO_HQ.jpg = DXO HQ with default setting 40ĮM1.2_ISO25600_0EV_EFC-DeNoiseAI-denoise.JPG = Topaz Denoise with Automatic settingsĮM1.2_ISO25600_0EV_EFC_DXO_HQ-DeNoiseAI-denoise.jpg = Topaz Denoise of DXO HQ with 40ĮM1.2_ISO25600_0EV_EFC_DXO_DeepPrime-DeNoiseAI-denoise.jpg = DeepPrime with 40 + Topaz Denoise with Automatic afterwardsĮM1.2_ISO25600_0EV_EFC_DXO_DeepPrime.jpg = DeepPrime with default setting 40ĮM1.2_ISO25600_0EV_EFC_DXO_DeepPrime75.jpg = DeepPrime with setting 75ĮM1.2_ISO25600_0EV_EFC_DXO_DeepPrime75_USM.jpg = DeepPrime with setting 75 + USM appliedĮM1.2_ISO25600_0EV_EFC_DXO_Prime.jpg = Prime with default setting 40įor Topaz I used the for first run the out of camera JPG (the RAW does not work better). You will find nine images for each ISO setting. I've uploaded the files to the Dropbox, so you can download them and compare in full size. I took an old Test-Setup Shoot I did in 2017 with my EM 1.2 from same scene with an ISO range from ISO 64 to ISO 25600 and processed them in DXO PL4 with Prime and DeepPrime and also with Topaz Denoise.
