Hmm, but if it was a mandatory lens correction controlled by the lens manufacturer, wouldn't the corrections be the same in ON1 as in LR? In LR, there is virtually no fringing on most of the parts of the photo that look like Christmas in ON1. It's one possibility - the other is that you can't turn off the lens correction as the camera/lens manufacturer could have made that correction mandatory (this is true for some manufacturers in Lightroom, I don't know if that situation is the same for On1). Does that mean it is not caused by bad lens correction? When I turn off lens correction in ON1, the green fringing stays the same. I am willing to bet that the lens profile On1 has for the lens in question is bad (possibly derived from a very bad sample) - and it's the defringing in On1 that is producing the green fringe (because the green color looks like the complimentary color to the purple you get). No worries! I appreciate what you said, as it was a good guess about what the problem might be. I have green defringing set to max in the ON1 version and no green defringing in the LR version and the green fringing is still awful. But it is not green fringing nor is it as bad or hard to remove as the green fringing in ON1. If I reduce purple defringing from 2 to 0 in LR, there is a little purple fringing in the LR version that is reduced by checking the 'remove chromatic aberration' box. I appreciate the reply, but that is not the issue. I should have specified that I turned off 'remove chromatic aberration' in LR for this comparison. No idea if On1 can do this but maybe you can find an option for this within the software. I don't use On1 I use Lightroom which can be set up to apply lens correction, CA etc on import. However your raw software cannot read this and it needs to be applied manually. You might have your camera set up to remove chromatic abberation/fringing which applies only to the JPEG rendering. The ON1 version has max green fringing reduction and no purple fringing reduction while the Lightroom version has no green fringing reduction and very slight purple fringing reduction. Both images have white balance at 5400, tint +6, and highlights -100. Below is a screenshot of the raw file in ON1 (left) compared to Lightroom (right) at 200%. I can remove virtually all of the green fringing with local desaturation of green using a color adjustment filter, but it still doesn't look quite right and that is a lot of work to do for green fringing that shouldn't even be there in the first place.ĭoes anyone have an explanation for this or any advice? I bought ON1 Photo Raw 2022 before I realized this problem and I really want to make it work as my primary editor. Converting the raw file to DNG prior to importing to ON1 does not resolve the issue. Using green defringing in ON1 does not fully remove it even at max and that causes issues elsewhere in the photo. Upon importing a certain raw file, I noticed very bad green fringing in several parts of the photo, where there is no visible green fringing on the OOC jpeg (when opened in ON1 or elsewhere) or the rendering LR provides with the same raw file, even without any green defringing applied in LR.

This problem was present in both 20 versions. I have been trying ON1 Photo Raw recently.
