Performing Automatic Color Corrections
All human flesh tones should reside along the flesh tone line. Because
flesh tones most often fall into the midtone luma region, you will probably
use the Midtones ChromaWheel to tweak chroma values, rather than use
the Shadows or Highlights ChromaWheels.
To adjust flesh tones using the Vectorscope:
After you’ve corrected your image’s luma contrast range and removed
color casts, you can focus on your image’s chroma values—particularly the
chroma of the image’s flesh tones.
1. Display the Vectorscope in the left color correction monitor by select-
ing it from the menu.
2. Make sure Hue Offsets > HSL tab is selected.
3. Examine how the Vectorscope is registering the video signal. Ask your-
self the following questions:
Does the signal display rest on the flesh tone line?
Does the signal display extend about one-third of the way from the
center of the circle?
4. If the signal needs to be tweaked for hue (the position away from the
flesh tone line) or saturation (the position away from the center of the
circle), adjust the Midtones ChromaWheel as necessary.
Yo u m ay n ee d t o d ra g the S at ura ti on s li der in th e C on t ro l s t ab to
increase or decrease the saturation along the flesh tone line.
Practice Your Skills
1. Open “Color correction sequence Part 2”, and park the position indica-
tor on the first segment, Rehearsal CC.
2. Select Toolsets > Color Correction to enter Color Correction mode,
if necessary.
All of the segments already have Auto Contrast applied.
3. From the menu in the left monitor, select RGB Parade.
4. Click the eyedropper below the Shadows ChromaWheel, and click
an area of the frame that is supposed to be black, such as the dance
instructor’s pants.
Watch as both the RGB Parade and the image adjust to remove the
color cast from the blacks.
NOTE The “Final bows”
segment was removed
from this sequence
because it did not exhibit
any major color balance
issues.
