Primer
Although primary color correction affects the entire raster, secondary
color correction is limited to specific geographic regions—for example,
vignettes or windows—or specific color vectors. Secondary color correc-
tion can also affect specific tonal regions, but these secondary regions are
more specific than the shadows, midtones, and highlights that are used to
qualify corrections in primary color correction.
As the tools have become more nonlinear, the distinctions between
what is primary and what is secondary are beginning to blur. For the
purposes of defining workflow, this distinction will probably never
totally evaporate, but the boundaries between these two terms are
more vague than they have been in the past. As a matter of fact, the
boundaries where secondary color correction ends are also beginning
to fall as more color correction applications are offering the ability to
add effects and filters to create exciting new looks. Another aspect of
the blurring lines between primary and secondary color correction is
that some definitions of secondary color correction describe it as being
corrections made downstream of the telecine. Color grading in the
years since 2000 have become increasingly detached from the telecine
or scanner so that now, virtually everything is done apart from a tele-
cine—if a telecine is involved at all. As of 2012, colorists rarely work
from telecined material. Either film scans or digital camera origination
is the primary source of material fed into modern color grading suites.
Even the telecined material is rarely graded directly from the telecine,
instead being transferred “flat” to an HD digital tape or directly to a
server. The flat grade is then corrected by the colorist without access
to the telecine.
Here are a few of the interfaces for secondary color correction
