Chapter 13 Managing Corrections and Grades 283
Step 4: Make modifications due to client feedback
Once your client has had the opportunity to screen the nearly finished grade of the
program, you’ll no doubt be given additional notes and feedback on your work. You
can use the Primary Out room, which up until now has remained unused, to easily
apply these final touches.
Moreover, because each step of the color grading process was performed in a specific
room of the Color interface, it will hopefully be easier to identify which client notes
correspond to the adjustments needing correction.
The steps outlined above are simply suggestions. With time, you’ll undoubtedly
develop your own way of managing the different processes that go into grading
programs in Color.
