Re: No need to change the default settings! Erase all of WIN 10
"I'd love to but as a semi-pro photographer I need Adobe Photoshop and Lightroom with the now unsupported Nik filters."
Darktable - www.darktable.org for Linux & Mac
I've used it for years for my Canon 550D & 6D, my cousin, a retired industrial photographer, is very impressed and so is his son ( a very well-known sports photographer)
RawTherapee also gets good reviews although I've not used it personally.
