Adjustment technique: First, adjust B color of
the point whose color is to be adjusted so that it
approximates that of point No.1. If R color is low at
this time, the image will have cyanish cast, in which
case increase R color. On the other hand, if R color
is excessive, the image will have a reddish cast, in
which case decrease R color. Overall, a cyanish
cast makes it easy to see color shading.
7. Next, view and make similar adjustments for
points No.4, 5, 12 and 13.
8. Then adjust points No.6 to 9 and No.14 to 17.
This completes the -MIN- tone adjustments.
9. Make similar adjustments for other tones as
described in steps 1 to 8 above.
