The only issue is that you might lose some detail during this process. Simply put, noise reduction software smoothes the photo to reduce the unwanted texture while decolorizing distorted pixels to match the surrounding colors. This type of noise is related to image exposure, high ISO numbers, and the size of the pixels. In contrast, luminance noise is colorless, and it looks similar to grain. It looks like a kind of colored, unaesthetic grain that is most noticeable in the dark areas of the photo. That said, there are two types of noise in digital photography: color noise and luminance noise.Ĭolor noise (also called chromatic or chroma noise) refers to hue variations between pixels. Like grain, it appears mostly when we work with high ISO, as we are “forcing” the pixels of the sensor. On the other side, digital noise is an unwanted signal that produces random variations of color and brightness in images. It is also worth noting that films with larger crystals are more sensitive, so they are associated with very high ISO values. The bigger the crystals, the bigger (and more noticeable) the grain. Grain only appears in analog photography, and it is a texture produced by the photosensitive crystals that cover the film. Final words Understanding noise in digital photographyįirst of all, although some people define the term noise as grain, they are two different concepts.13 Best Noise Reduction Software in 2021.Understanding noise in digital photography.Then I have to actively load my new tifs into Lightroom. If I run through Topaz directly, at the end I have both the original tif files (which I no longer want) and the modified tif files. One benefit of the Topaz plug-in from Lightroom is that tif files are first created and then overwritten to the same filename after Topaz processing, so there is no need for me to actively find and delete the original tif. It appears to add a few other cumbersome steps. I am able to take un-Topaz-processed tif files and load them directly into Topaz Denoise and work from there, but I have not figured out a good workflow with that technique. If no one has any solutions, please share workflow suggestions as workarounds. I have corresponded with Topaz support, and they insist that it is a bug in Lightroom. I do not believe it to be a memory issue, since I've watched the Windows Task Manager during the batch processing, and it doesn't get above 60% memory. ![]() Not sure if there is a log file somewhere with more information. ![]() There are no overt messages of any kind from either Lightroom Classic or Topaz Denoise, only my knowledge that there should be more files in Topaz but they aren't there. This is a huge workflow bottleneck as now it takes me much longer to process a large number of photos (I'm typically processing ~150-200). However, it is now at the point where, no matter how many times I re-do the process, it only loads a small number (sometimes 18, sometimes 25, etc) when it launches Topaz Denoise. Most of the time if it didn't work, it would work after I deleted all of the created tif files and re-tried the process. It used to be that sometimes it would load all of the tif files, sometimes it would load only a portion of them. It then launches Topaz Denoise AI and shows which files have been loaded. It first creates tif files for each raw file I have selected. Note that I have had this same problem on prior versions of both Topaz Denoise and Lightroom Classic.įrom Lightroom Classic, I use the Photo -> Edit In -> Topaz Denoise AI command. I'm wondering if anyone has had the same problem as I have on Windows with Topaz Denoise AI (v 3.4.2) run as a plug-in on Lightroom Classic (v 11.1).
