Darktable.org Fantastic Open Source Linux Software. Works on OSX and Windows. Must be a 64 bit computer. I like it better than Lightroom or photoshop. Did I mention it’s free ? The user manual sucks. Go watch tutorials on youtube Presets are “styles”. You can import Styles into the program on the Lightable tab; selected at the top and right under import. I’ll add a photo later today. Greg. .
