Nodes as layers, and why order decides what can be recovered
'Each node is kind of like a layer on that clip that lets you add multiple adjustments to.'
Right-click > Add Node > Serial (after) or Serial Before; Alt/Option+S and Shift+S; Ctrl/Cmd+D toggles a node, Shift+D toggles the whole grade. Reasons for many nodes: control order, reuse a tool twice (Curves for brightness, Curves again for contrast), mask per node. Order rules: badly-off brightness and extreme white balance go on a node BEFORE the log correction; mild fixes can go after. A typical chain - log correction → one or two masked nodes (sky/ground) → contrast → LUT node(s), sometimes several LUTs at low strength. Everything you might need to recover happens before the LUT, because a LUT's clipping is destructive to later nodes. The tour also covers the Color page: viewer, timeline/clips, node panel, Open FX, Lightbox, the tool row (Camera Raw, Color Match, Primaries, HDR wheels, RGB Mixer, Motion Effects, Curves, Color Warper, Qualifier, Power Windows, Tracker, Magic Mask, Blur, Key, Sizing, Keyframes, Scopes) and the Gallery for stills and PowerGrades. Mac fix: Preferences > General > Use Mac Display Color Profiles for Viewers; Project Settings > Color Management > Timeline Rec.709 Gamma 2.2, Output Rec.709-A; save as a preset and 'Save As User Default Configuration.'
The grammar of the whole module; the before/after-the-LUT rule is the one people get wrong.
