The one-page card to screenshot and reread before you open the color page. Correction makes the image true and consistent; grading (next chapter) makes it feel like something. Correct first, always.
The core idea in three lines
Correct before you grade. Neutral before pretty. A look built on a mismatched image amplifies the mismatch.
Read the scopes, not the monitor. Your eye adapts and hides casts; the scopes report the file.
Match every shot in a scene to one hero. Consistency across the cut is what reads as "a film."
The five reserved terms
Term
Definition
Color correction
Balancing an image to a neutral, accurate, consistent baseline: real black and white, no cast, natural skin, every shot matching. Has a right answer.
White balance (in post)
Neutralizing a color cast after the shoot by rebalancing R, G, B until something that should be neutral reads neutral.
Scopes
Real-time graphs of the actual signal — objective, unaffected by your eye's adaptation or your monitor. The three: waveform, RGB parade, vectorscope.
Matching shots
Making every shot in a scene share one consistent color and tone so the cuts are invisible and it reads as one place and time.
Primary correction
Whole-frame adjustments (the entire image at once), as opposed to secondary (isolating part of the frame — Chapter 32).
The three scopes — a reading guide
Scope
Measures
Neutral / correct looks like
Trouble looks like
You use it to
Waveform
brightness, 0–100%
trace spans 0% to 100%, nothing on a rail
piled on 0% (crushed) or 100% (blown); floating (milky/dull)
set black & white points, spot clipping, match tone
RGB parade
R, G, B balance
three channels level on neutral areas
one channel high/low = a cast
neutralize casts, match color
Vectorscope
hue (angle) + saturation (distance)
trace near center; skin on the skin-tone line
trace off-center toward a hue; skin off the line
judge cast direction & saturation, place & match skin
The skin-tone line: roughly the 11 o'clock direction (between red and yellow). Every complexion's healthy skin falls along this same angle — darker or lighter skin sits farther out or closer in along it, never at a different angle. The most useful landmark in color.

The primary-correction workflow (memorize the order)
One shot:
Normalize / set contrast — expand flat/Log footage; set black point to 0% and white point to ~100% on the waveform. No crush, no blow. Place midtones with gamma.
Neutralize the cast — on the parade, eyedropper a neutral reference, then refine with temperature/tint until R, G, B level.
Check skin — on the vectorscope, confirm faces ride the skin-tone line; nudge if needed.
Pick the hero, match the rest — correct the hero fully; match every other shot to it: tone → color → skin, verified on the scopes.
Play at speed — hunt for any cut where color or brightness jumps; fix those. Now it's correction-locked.
The shot-matching checklist
[ ] Pick the hero (widest / most story-important / closest to right).
[ ] Correct the hero fully to neutral.
[ ] Match each other shot's black point and white point to the hero (waveform) — tone first.
[ ] Match each shot's color balance to the hero (parade) — white walls the same white.
[ ] Match each shot's skin to the hero (vectorscope) — same point on the skin-tone line.
[ ] Play the scene at full speed; kill any cut that jumps.
Decision rules
Situation
Do this
Mixed light (two source colors)
balance for the dominant/story light (the face); let motivated practicals stay warm
Green cast (LED / fluorescent)
tint toward magenta
Warm or cool overall cast
temperature slider; confirm on parade
Flat / Log footage
expand contrast to the rails first, then balance; push gently if 8-bit
Shots don't match
pick a hero; match tone → color → skin
Two cameras
lock same manual white balance + same profile on set; still expect to match ~10% in post
No trustworthy monitor
trust the scopes — they read the file, not the screen
Bright sky
protect it on set (don't blow it); never push it through 100% in post
Top mistakes → fixes
Mistake
Fix
Crushing / blowing while chasing contrast
watch the waveform; stop the trace at the rails, never through
Correcting by eye
your eye adapts and hides casts — use the scopes
Grading before correcting
neutral-and-matched first; then one look lands the same on every shot
Over-neutralizing a warm room to sterile grey
balance the face; keep the room's motivated warmth
Pushing thin 8-bit footage too hard → banding
correct gently; shoot 10-bit next time if you'll push
Matching color before brightness
match tone first — brightness differences masquerade as color
"Correcting" skin toward a template
correct toward the truth of the actual person, every complexion
The on-set habits that make correction trivial (you shoot for the color pass)
Lock manual white balance — same number every take; turn auto OFF so shots don't drift apart.
Shoot a grey card (or white paper) under the light at the head of each setup → one-click balance in post.
Match picture profiles across cameras — never mix a Log camera with a standard one in one scene.
Expose on the waveform (Ch. 5) — protect highlights; a clipped sky can't be recovered.
Shoot 10-bit when you know you'll push color hard (Ch. 3) — headroom to correct without banding.
Craft principles in play
Principle
Here it means
Motivate every choice
keep motivated warmth (practicals, firelight, golden hour); don't erase it to neutral
You shoot for the edit
grey card + locked WB + matched profiles make the color pass fast
Story is the boss
correct toward the truth of the subject and scene, for every complexion
The project increment
Production Checkpoint: Color-correct Project 3 (and your other two projects) — balance every shot to a neutral baseline and match shots within each scene using the scopes. No looks yet. When you can play the whole piece and no cut jumps in color or brightness, it's correction-locked and ready to grade in Chapter 32.
The Café Scene, this chapter
Neutralized. The mixed cool-window / warm-tungsten cast is balanced for the face (the dominant light); the practicals keep their believable warmth; the four coverage shots are matched to the hero wide. The scene is now true — ready for Chapter 32 to grade it into the warm café look. The scene never changed — your command of it did.
