Managing Corrections and Grades
281
To copy an individual correction to a group:
m
Drag the correction bar of the room you want to copy from the Timeline onto any
group node.
The correction you dragged overwrites the settings in the same room of every shot in
that group.
Important:
You can only copy corrections and grades from the Timeline to groups in
the Shots browser.
Using the Primary, Secondary, and Color FX Rooms Together
to Manage Each Shot’s Corrections
Color’s interface for correcting and manipulating the color of your shots is extremely
flexible. While each room has individual controls that are tailored to specific kinds of
operations, some functions do overlap, and the Primary In, Secondaries, Color FX, and
Primary Out rooms collectively contribute to the final appearance of your piece. How
you use these rooms is entirely up to you.
At minimum, the grading of every project involves the following steps:
Step 1:
Optimize the exposure and color of each shot
Step 2:
Balance every shot in a scene to have similar contrast and color balance
Step 3:
Apply a creative look to the scene
Step 4:
Make modifications due to client feedback
These steps can all be performed within a single room, or they can be broken up
among several rooms.
Doing Everything in One Room
Excluding special operations such as secondary color corrections and Color FX, each of
these steps in the grading process could be performed via a single set of adjustments
within the Primary In room. In fact, for simple programs that don’t require extensive
corrections, this may be the only room you use.
