Mixing Light, FXPHD, Ripple Training, Lowepost, TACResolveTraining, iColorist, MonoNodes, and Demystify-color are all good. Each has something the other doesn't have, but they're all useful. The free textbooks and videos on BMD's site are also good:
https://www.blackmagicdesign.com/produc ... e/trainingThere are three decent Resolve basic tutorials out there that I recommend:
Mark Spencer's Ripple Training Resolve Tutorials:
http://www.rippletraining.com/categorie ... i-resolve/Patrick Inhofer's Mixing Light Resolve Tutorial:
https://mixinglight.com/Warren Eagles' FXPHD Resolve Tutorials:
https://www.fxphd.com/resolve16/I like all three for different reasons: Ripple's is very thorough and technical; Warren is very down-to-earth and provides practical examples; and Patrick goes into the basics and touches on non-obvious extras. Each does a very good job and is certified as a trainer by BMD. Lowepost.com and TACResolveTraining.com have some good tutorials as well. I have not been as impressed by the other tutorials on the web, frequently done by people with dubious credentials. Cullen Kelly and Darren Mostyn are rare cases of people with free YouTube videos who are exceptionally good.
Alexis Van Hurkman's book is also very good:
Color Correction Handbook:
http://www.amazon.com/Color-Correction- ... 0321929667Patrick Inhofer's "Tao of Color" newsletter and website are also informative resources:
http://www.taoofcolor.comThe LiftGammaGain website is also informative and has many hundreds of professional colorists as members:
http://liftgammagain.com/forum/index.phpThe BMD Resolve v18 manual is also very informative, and it's free, but you need time to go through all 4030 pages and try out every menu, every panel, every control, and every mode. Blackmagic also has several free textbooks on their training site:
https://www.blackmagicdesign.com/produc ... e/trainingBe aware that there are a lot of fly-by-night people out there presenting YouTube tutorials on Resolve. I would beware of anybody who has no credentials, no visible experience, and is not certified as a Resolve trainer by Blackmagic.
