Practical Tips for Using Color Correction
Color correction is one of the most complex and difficult areas of postproduction. For non-professional

No Exact Color Correction on the Computer Monitor
You should always evaluate any color correction on a calibrated video monitor or television. Because of
the different display technologies, the colors on the video monitor and computer monitor do not match.
Calibrating the TV Monitor
If possible, purchase a dark-blue filter (e.g. Wratten 47B), which will allow you to simulate the Blue Only
(Blue Check) feature available on professional video monitors. You’ll find this filter in any of the better
photo stores.
If you happen to be reading the printed version of the Reference Manual, you can also go to this section
in the online PDF file where the illustrations are in color. In Avid Liquid, press
F1 and go to the PDF tab.
1 To calibrate a typical TV monitor, use the SMPTE color bar test pattern from Avid Liquid (by
default located in ..\My Documents\Avid Liquid\Testpattern\NTSC). Load SMPTE Color Bars
(NTSC) to a Project and then to the Timeline or Clip Viewer so that it will appear on the TV mon-
itor:
