![]() ![]() Storage needed for the DNG files is two to four times greater than the original raw file. Other than the additional processing time when using PureRaw, I found another small drawback-the increase in file size. I settled on using DeepPrime on raw files unless I had a large number from a single assignment. It further extends the low-light capabilities of Prime denoising by combining that process with demosaicing to recover image and color detail that are often lost in raw file conversion. DeepPrime generally lies between the two in processing speed depending on the power of your CPU/GPU.It’s also the slowest of the processing options. It uses DxO proprietary Prime noise reduction technology, and from my experience the resulting noise reduction is extraordinary. Prime is an earlier DxO process designed for images shot in low light at high ISO settings.The speed gain is welcome when you process an entire folder of raw files. HQ processing is the fastest and is suited for images exposed under normal lighting conditions at reasonable ISO settings.The difference lies in the level of noise reduction applied. Three methods are available: HQ, Prime, and DeepPrime. The only real internal option offered in PureRaw is the type of processing to apply to your files. I never did and never found it to be an issue, but the non-Adobe software required different color and contrast adjustments to match the look of the same image processed in PureRaw and passed on to Photoshop or Lightroom. Other software would require you to turn off these instructions manually, if possible. When you export PureRaw DNG files to Adobe programs, there are instructions embedded in the XMP metadata to instruct the raw conversion algorithms not to apply denoising or lens corrections. This is a result of the non-Adobe programs applying their own DNG conversion algorithms to the files.ĭxO created PureRaw to be especially compatible with Adobe imaging programs (Photoshop, Lightroom, and Photoshop Elements). All the programs were able to read the DNG files, but the exposure, color, and contrast were slightly different in each. I opened DNG files that I created with PureRaw in Affinity Photo, ON1 Photo Raw 2021, Exposure X6, and Skylum Luminar AI Master, as well as Adobe Lightroom Classic 2021 and Photoshop CC 2021. PureRaw leaves the rendering of the file (white balance, color, contrast, etc.) to the user’s personal taste and vision by creating a DNG file you can process in your favorite image enhancement program. ![]() These are all described as linear restorations from the numerical data. PureRaw converts the raw file’s numerical data into an RGB image (demosaicing), reduces image noise (denoising), and applies optical corrections (vignetting, optical distortions, chromatic aberrations, sharpness) based on DxO optical modules. Unfortunately, camera manufacturer software is only now reaching a level of ease-of-use that’s attractive to users, and who wants to learn a new image processing application if you’re comfortable with your existing workflow (even if you’re sacrificing a bit of quality)?ĭxO PureRaw is a solution. This is one reason why raw files processed in software provided by camera manufacturers generally result in sharper, more detailed, and less noisy images. Most major image processing software companies pay less attention to raw file conversion than to image adjustment. DxO’s new PureRaw software performs that step, then passes the image file to your favorite software for adjustment. That first processing step, converting unprocessed data to a viewable image, is the most critical aspect of getting an optimal result. This data is first processed in a raw file converter by image processing software before image adjustments (white balance, exposure, contrast, etc.) can be performed. Raw files record the numerical data that the sensor measures at each photosite. To achieve optimal quality in final image output, you must start by capturing images in a raw format file. ![]()
