I’ll therefore be using a 60% setting in the testing BUT that could be too strong for some images. At 60% noise reduction in sample 2, there is a hint of noise at 200% magnification, but the image is more appealing. But what I don’t like about the result is that it appears a little too smooth, especially in the sand of the beach. At 100% noise reduction used for sample 3 there is no visible noise at 200%. When viewed at 200% magnification it’s easy to see Luminance noise, although it’s not unpleasant. Sample 1 shows the default 40% noise reduction. After running a few tests of a very noise RAW file from a Panasonic LX5, I realised how much difference this setting made to the results as seen here (click the image to enlarge). Initially I was going to set the DeepPRIME option to the automatic level which seems to be 40% Luminance reduction. Now back to the point about the Luminance slider in DxO PhotoLab. I’ve selected these because they are all old RAW files shot around 10 years ago when digital technology wasn’t as advanced, and the cameras are all very noisy. For this article I’ll be using RAW files from a: The final point to consider is that there could be variation between different manufacturer RAW files. This is a problem if you use an unsupported camera like the Fuji X Series and means that PhotoLab isn’t for you. In the Case of DxO PhotoLab, I can only use the DeepPRIME and Lens Correction options with RAW files.Ī further limiting factor in the DxO software is that there need to be supporting modules for your camera and lenses. Images that have already been processed to a TIFF or JPEG produce noticeably inferior results. To get the best image quality using On1 NoNoise AI and DxO DeepPRIME you need to be processing RAW files. It’s also worth mentioning RAW files used for testing as this could be important in the results. Again, I will leave these at their default settings. The Lens Correction option is either on or off, but the Lens Sharpness settings can be adjusted. It seems reasonable to use these given the features of On1 NoNoise that I’ve chosen to use. The other options in PhotoLab are the Lens Correction to remove distortion and Lens Sharpness to correct lens softness. This seems to always default to 40% when using the auto option and I’ll have more to say about this shortly as it’s quite important. It’s either on or off although there is only a single Luminance slider. With respect to using DxO PhotoLab and DeepPRIME, I don’t have much control. I’ll therefore also leave these at their auto and default settings. The other feature in NoNoise AI is that it applies Detail enhancement and sharpening to the image. I also won’t be using any of the advanced masking options but instead apply the adjustment to the entire image. Rather than try to fine tune each image, I’ll be using the auto option in the software. When using On1 NoNoise AI it’s possible to vary the level of both colour and luminance noise reduction. If you want to understand this further, I’ve published an article explaining how. It’s also possible to replicate it’s features using DxO PhotoLab, which is what I will be using for the testing. PureRAW is a RAW file pre-processor which removes noise and corrects optical problems in RAW files. Probably the nearest comparable of these to On1 NoNoise AI is DxO PureRAW. Compare this to DxO DeepPRIME and you’ll find that it’s a technology used in a couple of DxO products (currently PhotoLab and PureRAW). On1 NoNoise AI is a dedicated noise reduction application. I’ll break my approach down into three areas: Because of this I want to set out my method so that you understand how the testing took place. Whilst comparing On1 NoNoise with DxO DeepPRIME may seem easy, there are a lot of variables that could skew the results. Given the level of interest and that I’m curious as well, I think it’s time for an On1 NoNoise Vs DxO DeepPRIME challenge. It’s extremely well respected and produces very good results. If you aren’t aware, DeepPRIME is the noise reduction technology used by DxO in their PureRAW and PhotoLab Elite products. Since publishing my review of the recently launched On1 NoNoise AI software I’ve received more than a few emails asking how it compares to DxO DeepPRIME. On1 NoNoise Vs DxO DeepPRIME Noise Reduction
