Color correction and color grading are different jobs. Correction fixes problems — exposure mistakes, color casts, inconsistency between shots from different cameras or times of day. Grading (next lesson) adds a creative look on top. Always correct before you grade; a stylized look built on a technically broken image just looks broken with a filter on it.
Why Trust Scopes, Not Just Your Eyes
Your monitor's calibration, ambient room lighting, and even how tired your eyes are all distort what you perceive. Video scopes (Window > Lumetri Scopes) show the actual numeric values in your image, independent of any of that. The three you'll use constantly:
- Waveform (Luma) — shows brightness distribution across the frame; 0 at the bottom (pure black) to 100 at the top (pure white/clipped)
- Vectorscope — shows color/hue distribution as a circle; skin tones should fall near the "skin tone line" printed on the scope
- RGB Parade — shows red, green, and blue channels separately as waveforms; used to spot color casts (if blue sits noticeably higher than red and green across the image, footage has a blue cast)
Keep a scope open while grading. What looks correct on an uncalibrated monitor and what scopes report are often different, and scopes are what stays consistent across every screen your video is eventually watched on.
Basic Correction Workflow
In the Lumetri Color panel's Basic Correction tab, work roughly in this order:
- White Balance — use the eyedropper on something that should be neutral gray/white to remove a color cast first; everything after this step is easier once color is neutral
- Exposure — sets overall brightness; watch the waveform, aim for a good spread across the range without clipping (crushing to pure 0 or blowing out to pure 100 unintentionally)
- Contrast — expands or compresses the range between shadows and highlights
- Highlights / Shadows — recover detail in blown-out skies or crushed dark areas without affecting the overall exposure
- Whites / Blacks — set the true white and black points of the image
Matching Shots
Footage from different cameras, lenses, or times of day rarely matches straight out of the camera, even within the same scene. To match one shot to another:
- Grade your reference shot (the one that looks best) first
- Open the shot you're matching, and use the vectorscope/waveform side-by-side with the reference to compare
- Adjust white balance and exposure on the second shot until its scope readings resemble the reference's, then fine-tune by eye
Premiere's "Shot Match" feature (in Lumetri Color's Basic Correction, the icon next to White Balance) can auto-match two shots as a starting point, but it's rarely perfect — always review and adjust manually afterward.
Skin Tones
Skin tone accuracy matters more than almost any other part of a grade, because viewers are highly sensitive to it even if they can't articulate why a shot looks "off." Use the vectorscope's skin tone line as your reference: real skin tones across all ethnicities plot close to this line when correctly balanced. If corrected skin looks orange, green, or magenta-tinted against that line, recheck your white balance step before adjusting anything else.
Working in a Color-Managed Sequence
Modern Premiere projects use automatic color management by default, interpreting each clip's color space and converting it to your sequence's working space. Generally leave this on unless you have a specific reason to intervene — it prevents mismatched color spaces (e.g., footage shot in a camera log profile alongside standard footage) from looking wildly inconsistent before you've even started grading.
Applying Correction Across Multiple Clips
Once you've corrected one representative clip well, right-click it in the timeline and "Copy," then select other clips from the same camera/scene and "Paste Attributes" (choosing just the Lumetri effect) to apply the same base correction, then fine-tune each individually. This saves significant time on multi-clip scenes shot under consistent lighting.
