A helpful technique to use when adjusting the colors and gray shades
is to “overshoot” as you adjust to emphasize the effect that the
current adjustment is having to the overall image, and then to back off
to fine tune. This helps to give an intuitive feel for the process.
It is often helpful to iterate between the full white and gray fields and
actual video images to fine tune the system. Avoid making major
changes when adjusting to video images, as this can throw off the
white or gray balance. Remember also that the input level adjustment
has a large effect on color, and the input level adjustment procedure
must
be followed for each source prior to color balancing.
