![]() I prefer to add vignetting in software, where you have full control over it. something not all users necessarily prefer. Instead Photo RAW seems to want to jump in and apply all lens correction simultaneously for me. So I wish Photo RAW would allow me leave in both the vignetting and the lens distortion just like both DxO and LR do. I also prefer to leave in the vignetting. If that trick doesn't work I just use the vignette feature in the effects mode. I like to use the vignetting feature (often adding from zero) as full frame shooting has necessitated this for me. Correcting lenses for distortion involves digital stretching/resizing which the developers may simply have chosen to offset for with a touch of applied sharpening. ![]() When I think about this, there may be a correlation. With lenses that have very little distortion there seems to be less of a sharpness change. The strength of the sharpening effect seems to vary a bit for me dependent upon which lens is being corrected for. I then turn off the detail feature in the develop mode or choose a similar lens for the correction feature that doesn't do this. This is the same behavior I get when adding detail beyond a certain point in certain images-sometimes even just sliding up to 1 on the detail slider in any effects filter. Sometimes, when I use the lens correction feature, I get highlights and blacks blowing indicators. I have not noticed additional sharpening directly but can deduce that it does. I click lens correction and the whole file sharpens up a bit. ![]() Speaking of default sharpening, do you find that ON1 also automatically applies some sharpening when lens correction is applied to fix distortion? It seems to do that on my RAW files. Having said that, I find the unsharpened output from On1 to be sharper than the default sharpened output from Lightroom. A "new user" has no photo library to pore through.Lightroom applies sharpening by default (unless you've turned it off) whereas the sharpening in On1 is applied "to taste" via the 'Detail' menu. ![]() That could also point to a problem with PR's indexing function. That's where we are at and are trying to diagnose. This points to some sort of conflict between PR and the existing programs. Amazingly, the CPU usage was minimal and the machine ran normally. Interestingly, one of the engineers suggested creating a new user and installing On1 under that user. We did multiple screen shares, system dumps, PR log dumps, and did not uncover the underlying problems. PR 2018.1.1 ran fine on my MBP but 2018.5 caused the CPU to max out, the fans blaze, and the machine ran unbelievably hot. First, I've been using On1 products for years. They have been very concerned and responsive trying to diagnose and remedy the problem. I've been working with the On1 folks for a while over this issue. It should be enough for normal smooth editing I think. I have a four years old mac mini, 16 gb ram. So this means for me 2-3 pictures editing before taking a breake. My computer is running hot when I use it! I can use it 15-30 minutes and then it's so hot so I must quit and let the computer cool down. When I did use ON1 Photo RAW 2018 it was ok.
