Primaries: Lift, Gamma, Gain and Offset
The primary wheels are the core of a Resolve grade. Lift moves the shadows, Gamma the mid-tones and Gain the highlights, each in both colour and level. Offset shifts everything together, which is handy for correcting an overall cast in log-style footage. The same primaries can also be shown as Primary Bars, Log wheels, which target narrower tonal ranges, or HDR wheels.
Curves
The Custom curve edits contrast and individual red, green and blue channels. The hue curves are where precise colour work happens: Hue Vs Hue turns one colour into another, Hue Vs Sat calms or boosts a single hue, Hue Vs Lum makes it lighter or deeper, Lum Vs Sat pulls colour out of the shadows or highlights, and Sat Vs Sat tames only the colours that are already strong.
Qualifier and Color Warper
The Qualifier selects pixels by hue, saturation and lightness, so a correction can affect only a sky, a jacket or skin. Color Warper drags colours around on a grid, which is a faster way to make broad palette changes, such as pushing greens towards yellow for an autumn feel. Version 20 added Chroma Warp inside the Color Warper.
- Keep correction and look on separate nodes so you can bypass either one to compare.
- Watch skin on the vectorscope: healthy skin of any tone sits close to the skin tone line.
- Grade at the size you will deliver at; small previews hide noise and fringing.
