Colour Science & Grading
From log to final look — colour spaces, node structure, and building your signature grade
Focus: colour space theory, scopes, and your 6-node grade structure. Learn to read the parade scope before touching any controls.
  • Colour spaces — what they defineS-Gamut3.Cine is Sony's wide-gamut colour space — it covers more colours than any display can show. Rec.709 is the standard for HD TV and web delivery. DCI-P3 is the cinema standard. When you grade, you transform from the capture space (S-Gamut3.Cine/S-Log3) to the delivery space (Rec.709) — either manually via a CST node or via Resolve's Colour Management system.
  • The scopes — waveform, parade, vectorscope, histogramThe waveform shows luminance across the width of the frame. Target: blacks at ~16 IRE, mid-tones around 50, highlights below 100 IRE. The parade shows red, green, and blue channels separately — when all three are equal, the image is neutral. The vectorscope shows colour saturation and hue — correctly white-balanced skin tones fall on the 'skin tone line' at approximately 1 o'clock. Use all four together — no single scope tells the whole story.
  • Node structure — the architecture of a gradeThe recommended structure for S-Log3 footage: Node 1 (Input Transform) — CST from S-Gamut3.Cine/S-Log3 to your working space. Node 2 (Exposure/Balance) — correct overall brightness and white balance. Node 3 (Contrast) — set lift, gamma, gain. Node 4 (Saturation/Colour) — colour toning and creative choices. Node 5 (Qualifier) — secondary corrections. Node 6 (Output Transform) — transform to Rec.709. Label every node (right-click → Node Label).
  • White balance correction in ResolveCorrecting white balance: use the Colour Wheels offset to shift toward neutral. Or use the Curves → Custom → Sat vs Sat to de-saturate a neutral grey element. The most objective method: on the parade scope, adjust the R/G/B gain until any neutral area shows equal R, G, B values. Always verify against the parade — not just by eye.
  • Matching FX30 and a6700 in ResolveThe FX30 uses Venice-derived colour science; the a6700 uses standard Sony colour science. In S-Gamut3.Cine/S-Log3 both look nearly identical ungraded but diverge slightly when transformed to Rec.709. To match: grade one camera to your target, grab a still, then on the second camera's clip apply a CST node and adjust until scopes approximately match. Fine-tune by eye. The key difference is in the skin tone hue angle — the FX30 tends slightly warmer in the reds.
