You will notice that the horizon is not level. Which noise reduction plug in /editing software is the most effective? To conduct the test, all I have done is opened the raw file in Adobe RAW, selected the lens correction and chromatic aberration options, click on the ‘auto’ tab to lighten the image up so that you can all see the noise much more clearly, applied the relevant noise reduction treatment and then saved the images as a JPEG sized at 2048 pixels on the longest length. Clear (an even more sophisticated version of DeNoise whose results vary whereas the standard DeNoise applies the same level of noise reduction for each image). So I decided to run a comparison test on the single image that you see below, with the intention of ending up with four images that will show you the difference between not using any noise reduction at all, using Nik Define, using Topaz DeNoise and using Topaz DeNoise A.l. I ran an image that I took at night over Derwentwater in the Lake District last month and it is very noisy indeed. So I downloaded Topaz DeNoise on a free 30 day trail with a purchase price of $79.99 (approx £65.00) should I wish to purchase afterwards. It is not outstanding but it is better than most of the plug ins /programs that I have tried. I currently use Nik’s Define plug in and up till now, it has done a solid job. As someone who shoots with a Canon EOS R at night (on occasion in Lofoten / Iceland /Canada), and someone who would definitely like better noise reduction as the noise levels are high enough in camera (without running long exposure noise reduction in camera), I am always open to trying out new programs /plug ins to assist me in removing noise. He also mentioned that he had run the image through the Topaz DeNoise noise reduction software and found it to be quite simply amazing. Example of results obtained vs the drizzle function in Autostakkert! can be found here.A good friend of mine shared on Facebook three versions of the same image shoot with his Canon 7D MK2 stating that the noise levels were higher than he’d like. DOWNLOAD NOW In this 2023 Topaz DeNoise AI review, you’ll find an in-depth analysis of and tutorial for this noise-reduction software from Topaz Labs. This utility is extremely useful to enlarge image of small objects: planets, planetary nebula, small galaxies. Topaz Labs also offers such as Sharpen AI and Gigapixel AI (picture size enhancement) that may worth to test. Overall a great addition to my range of processing software. Processing time may be a bit long (10-30s) especially when experimenting with several settings combinations.Įxample of use can be found here. Having the left comparison window offering the last tweak beside the initial image, to better refine settings Some features that could be implemented to improve user experience: Topaz DeNoise has six sliders for removing noise, two for improving detail and edge sharpness, and one for adding grain. It seems that the intensity or location (to a lesser extent) of these patterns depends on the region of interest selection, so checking the tweak in different regions of the picture is a must.Īlways save pictures versions with various denoising intensity as in the heat of refining settings, it is very easy to end up with over-processed images. It may induce some artificial patterns (oriented grains, small tiles, or "crocodile skin effect), or small unnatural artifacts so one must be cautious. I use it as a standalone application, not in PS. It gives a nice final polish, and could even bring back to life some old pictures I considered lost. Denoise AI is a superb tool to remove noise without losing details, and it works well in many cases (planets, nebulas, clusters.).
