![]() The insights the neural network has gained are significantly more effective than any model designed by humans. DxO harnessed its expertise in raw conversion, its unique dataset, and a substantial amount of computing power to train a deep neural network to jointly apply demosaicing and denoising. This approach is significantly different from the algorithms based on mathematical models that are commonly used in other raw converters. In DxO PhotoLab 4, these two challenges have been solved utilizing deep learning, a method adopted from the field of artificial intelligence. We developed a method that allowed us to extract billions of noisy samples from this dataset and use them to train our neural network.”ĭemosaicing and denoising are two key steps involved in converting raw image sensor data into beautiful photographs. While these images were originally intended for calibration, it turned out they were exactly what we needed to create DeepPRIME. “Since the company’s founding, DxO has been amassing a dataset of raw images that contains countless shots from all cameras at all ISO levels. “The most challenging task in deep learning is gathering training data,” explains Wolf Hauser, DxO’s Image Science Director. By leveraging deep learning, DeepPRIME improves image quality by up to two ISO stops compared to PRIME. Today, DxO unveils the successor to its award-winning PRIME denoising technology. Perhaps this is the thing that will make me finally convert an image in two ways and combine the two with masks later to get exactly what I want out of an image.DxO has been committed to making the world’s highest-quality raw converter for more than 18 years. I definitely like to have the choice, and knowing that it is possible I will certainly play with that slider a lot in upcoming conversions. The standard value of 0 gives a little more sharpness, but for the cost of more noise in the uniform background than I could see in the image that was developed by PL5 with DeepPrime. When I choose to eliminate all the noise (-100 on the slider), the background turns out very smooth, while not giving up that much fine sharpness. I tested it on a macro image with a background that should be mostly uniform, so any difference in noise will be very visible there. The thing distinguishing DeepPrime XD from DeepPrime (or rather: PL6 from PL5, because in PL6 the slider is there for both DeepPrime and DeepPrime XD) is the addition of a slider ("Rauschmodell", translates to "noise model") to decide how much noise you are willing to exchange for more sharpness. Here are some samples, utilizing both DeepPrime XD at "magic wand" default levels and the Wide Gamut (K-3 at ISOs 5000, 4000, 2000, and 500, respectively, all processed to taste you can view full-res JPEGs on my SmugMug website by clicking on the samples): I will upgrade from PL5 as soon as my budget allows, although I'm hoping to get a slightly better deal when my trial expires or in the Black Friday sales. I did notice that with some images I will have to use the "Protect saturated colours" slider a bit more to avoid colour clipping, but the results still look better than before. ![]() Encouraged by SmugMug's recent announcement that they now retain wider colour spaces of uploaded images, I also gave the DxO Wide Gamut a try, which indeed leads to richer, more natural-looking colours on my BenQ SW2700 when I switch it to AdobeRGB. ![]() Played around fairly extensively with the trial version of PL6 and came away quite impressed with the DeepPrime XD noise reduction, which is significantly more effective in removing noise than the regular DeepPrime and also better at retaining meaningful detail. ![]() What are your thoughts, will you upgrade or even get it new (209€ for the PL6 Elite version is steep though!)? ViewPoint 4 seems even less enticing when you already have version 3. "Expanded working colour gamut for increased accuracy" and Soft Proofing - don't think I would benefit from that in a significant way. The ReTouch Tool looks nice, but I can achieve what I want within FastStone I will probably have a look at the test version though. I don't think I need more or better than what DeepPrime already offers. So if that stays true for the next major version, I will probably upgrade then. I currently have PL5 Elite and could upgrade for 99€.
