Well I capitulated and downloaded the trial before upgrading and have to say quite impressed thus far, it's faster and one thing I wanted was the ability to install my own camera profiles, after doing so I created two profiles, one with On1 2020 and one with Lightroom 6, I thought they would be the same but I honestly thought the On1 gave a better result, asked the wife who has no clue about photography PP and she picked the On1 2020 version also after a bit more investigation into 2020 I cancelled my upgrade to Skylum Luminar 4 because I don't or would very rarly use this AI sky replacment and when I asked about the option to use 3rd party plugins with the Windows version I was told still not possible even in version 4. Going back to the camera profiles, I can make them with my Colourchecker and they show up in the list within the software but I only did the one as a quick test but now cannot figure out how to remove it from the list, I no how to remove it from the Windows COLOUR folder but not the software itself so anyone can help with a soulution please? Thanks, Russ.
