The parade scope helps you optimize highlights, mid tones and shadows.
The 'lift, 'gamma', 'gain' and 'offset' color wheels give you total control over the
color and tonal balance of your clips. To make a uniform adjustment to all colors
for each tonal region, drag the dial underneath the color wheels back and forth.
1 Adjusting the 'lift'
With your first clip selected on the color timeline, click on the 'lift' dial underneath the
first color wheel. Slide it back and forth and watch how it affects your image. You'll
see the brightness of the dark regions of your picture increase and decrease. Set it to
where you want the dark areas to look their best. If you decrease the lift too much,
you'll lose details in the blacks and you can use the parade scope to help avoid this.
The optimal position for blacks on the waveform is just above the bottom line of the
parade scope.
2 Adjusting the 'gain'
Click on the 'gain' dial and slide it back and forth. This adjusts the highlights which are
the brightest areas of your clip. The highlights are shown on the top section of the
waveform on the parade scope. For a brightly lit shot, these are best positioned just
below the top line of the waveform scope. If the highlights rise above the top line of the
waveform scope, they will clip and you will lose details in the brightest regions of
your image.
3 Adjusting the 'gamma'
Click on the 'gamma' dial underneath the color wheel and slide it back and forth. As
you increase the gamma you'll see the brightness of the image increase. Notice the
middle section of the waveform will also move as you adjust the gamma. This
represents the mid tones of your clip. The optimal position for mid tones generally falls
between 50 to 70% on the waveform scope. However, this can be subjective based on
the look you are creating and the lighting conditions in the clip.
