Lens correction is obviously lens/camera specific, but apparently the sharpening is too, and sometimes it overcompensates.īy turning off the module, you give up lens correction as well as sharpening, but most good photo editors also have lens correction, so you still have both lens corrections and sharpening, but you have control over them, which you don’t with PureRaw. The program still performs the excellent DeepPrime noise reduction and reduction of demosaicing artifacts, but it does not do sharpening or lens correction. I discovered you can click the “Modules” button and disable the use of the module during processing. I haven’t figured out what determines this, but it seems like an image that’s low-contrast tends to get sharpened less than images that are high contrast, but I’m sure that’s probably not the whole story. It turns out that some of the Nikon raw images also get over-sharpened in PureRaw. Please, DXO, add the ability to disable sharpening in this tool!
I understand that DXO are trying to make this a 100% “push the button” tool, and it works great for the objective things, but there absolutely needs to be an option to disable sharpening!Īs a work-around, I have found that I can use the “contrast by detail level” tool (essentially contrast by wavelet level) in the RAW tool that I use to mostly undo the over-sharpening, but it’s not 100% perfect, and most importantly, I shouldn’t need to add this extra step after using a tool that is supposed to make the workflow easier. For most people, this much sharpening (or any sharpening for that matter) should not occur this early in the workflow. Sharpening is subjective and will vary among photographers and from subject to subject. PureRaw is extremely good for the objective things that it does, like remove demosaic artifacts, noise reduction, and lens corrections, but it over-sharpens and with too large of an effective radius. I even filed a support request about it, but haven’t received any reply yet other than it will be sent to the appropriate people.
