Depending on which ML model they used, DeNoise AI likely developed a pattern recognition model based on neural nets or probabilistic models based on Bayes or Markov. They trained the software with several million images containing noise, along with several million clean images. You’ll want to click on the images to zoom in so you can see the dramatic difference this tool makes.ĭeNoise AI claims to use machine learning as a means of identifying noise. I’ll show you some comparisons to other NR techniques I’ve used in this post. My wife and I have been chasing the Northern Lights for several years now, and trying to clean up our shots has always been a challenge. Noise reduction has been the bane of my existence ever since I started astrophotography. After seeing the results turn out so good, I needed to take some time to talk about this tool. Topaz Labs recently released DeNoise AI, a noise reduction tool for photographers, and so naturally I picked up a copy after reading about a sale on Nikon Rumors. You may not get the Affiliate offers if you do this.Topaz Labs DeNoise AI review by Jonathan Zdziarski ( 500px) – see the original blog post for more sample photos ( DeNoise AI coupon code is available here): You can avoid this reward by googling the software and using the normal search results. That means that if you follow my link to the tool and then purchase it, the guys at the Labs will give me some pennies as a thank you. * Full disclosure: I love this tool so much and use it every week, so I am an approved Affiliate of Topaz Labs. If you have any others, please let me know! That’s kind of the run down on my list of tips for this tool, I think this should answer all of the questions I’ve seen about it (I hope!). You can also adjust your brush settings to suit the area being targeted. You can invert the masks and switch on and off the overlay. Use the Sub (black) and Add (white) brushes to regain detail where needed in a targeted way. That means that DeNoise is effecting the whole image evenly. Using the mask button will give you a white mask. Sometimes you want the details back in places and with some subjects, you lose all coat detail completely (*achem* Horses…) so in these situations, it’s time to mask. Keep sharpening set low, under 10 is usually more than enough! You can always do a high pass sharpen later. Then, increase slowly in little sections until your noise is removed appropriately. My advice would be to turn both sliders right down – like 2 or 3 or 4. The “Auto” settings always overcook the situation for me! Way too much sharpening, the introduction of artefacts and other weird things tend to happen when Auto is running the show. I’ve never used AI Clear, but regularly switch between DeNoise and Low Light depending on the coat of the dog and the level of noise in shot.
