5/16/2023 0 Comments Denoise online![]() ![]() I used to fight with noise with my D7000, bought a Z 6 and pretty well stopped having to do that. I know this isn't a specific answer to your question, but I think it bears saying. In short, PhotoLab gets me a crisp, clean, well-corrected image that's ready for print prep with less work. Often, I can get similar detail from Lightroom by manually applying fine USM, but that's extra work I don't have to do with PhotoLab, and the latter's automatic geometry corrections are better, too. $200 to gain two more usable stops from all of my cameras and lenses? Take my money!Īs an aside, since you mentioned print sizes as well as noise reduction, DxO's lens profiles yield superior detail from all my RAWs, regardless of ISO, than what I get from Lightroom defaults. If you shoot high-ISO a lot, this is a game-changer.Īs an event pro, I consider DxO PhotoLab the single most cost-effective investment I can make in improving the image quality of my work. I find that DeepPRIME gives me about two more stops, which lets me shoot event work with my a7RIII at ISO 25,600 and still get images that'll look good in a 24" print. But, it's especially useful at the threshold where a camera begins to give up noticeable amounts of detail - around ISO 3200 with Micro Four Thirds and ISO 6400 with 35mm format. At base ISO, DeepPRIME nicely removes the subtle noise that can appear in a blue sky. Noise reduction can be useful at all exposure (ISO) levels. That said, I find DxO's DeepPRIME and DeepPRIME XD remarkably good at mining detail from high-ISO images that would otherwise look like mush covered with rainbow sprinkles if processed with Lightroom. Not even the Platonic ideal of noise reduction could make a high-ISO image yield the same level of detail as a low-ISO version. It depends a lot on what you shoot, how little light you have to work with, and what your expectations are.įirst, a level-set: Good noise reduction doesn't remove detail, because, especially with high-ISO images, that detail was never in the file in the first place. Only way to better that is to go full frame and I do not want that. I sacrifice shutter speed over ISO which is only possible due to in-body stabilization (Pentax shake reduction system) and I use the KP which delivers one of the best low-noise, high-ISO raw files I can find in the APS-C world. I tend to go easy on the NR and try to use masks as much as possible to keep it from destroying too much fine detail but the main strategy with image noise is to avoid capturing it to begin with. Darktable's profiled NR has also improved greatly over the years. I acquired NeatImage (native linux version) and have updated several times at reasonable rates over the years. I am mainly asking this question to those who print at least 11 x 14 or A3. AI can take a stab at filling in shapes and contours but there is a physical limit, entropy increase is an irreversible process. ![]() Well, even the greatest NR software cannot bring back detail where none was captured. It seems to remove noise at the expense of smearing or blurring detail. I have demo-ed all three and find the results can be somewhat disappointing in some cases and just OK in others. The ones that come to mind are the big three 1) Topaz Denoise AI, DXO Pure Raw 2 and On1 No Noise AI. I am posing this question to those of you who have added denoise software to your workflow outside of Photoshop, Lightroom, Capture One etc. Equivalent to using Topaz standalone app in RAW mode but with better results from DXO (in my opinion of course), and less clicking involved Where it differs with DXO is that it's technically impossible to mess it up, can't make this "human error" because even if you trigger the processing from within Lightroom, it still takes the actual raw file. And to be fair to Topaz, this is also their recommended way of using it. Else it can produce circular blotches/lumps in out of focus areas, as if it thought that noise in this region, enhanced by global sharpening, is actually something to recover and not get rid of. with Lightroom, if you imported your pics and your default profile applied global sharpening at import, you absolutely have to turn off the sharpening before you send the file to Topaz. It has to do with global sharpening that is usually applied to raw files by default in your Lightroom or whatever else you use, the main thing with Topaz is that you must feed it a file without any sharpening applied. I was looking for examples to show what I mean by Topaz producing ugly results when used badly, sorry to say I deleted them all, ![]()
