Stefano Virgilli - Adobe Certified Instructor Design Master @LAB School - will guide you in a deep retrospective of colour evolution. Where did we start from in digital photography, we are we heading to it. Any feedback?

Being a doctor who "cures" photos
Histogram, Levels, Curves, Colour Balance, Channel Mixer, Exposure, Recovery, FIll Light, Blacks, Brightness, Contrast, Temperature… Isn't this enough? Or too much? It's a jungle out there!
Before to embark in a long journey with Camera Raw and Lightroom, do you really understand WHY are you using this or that adjustment?

RESET! Start from the beginning and analyze what's right and what's wrong with a picture. Only then we can try to "fix it".
