you must apply these features to the image in that window and not in the
preview image or the After image beneath.)
As you use these buttons with one of those images, two clicks are required
for this feature to be performed. First you click on one of these buttons, for
example the White Pointer button; the pointer changes to an eyedropper
representing the button. Suppose that you click the White Pointer; then the
second click should be on a spot in the Settings tab image (or the After
image on the other tabs), that you know should be white. The color balance
of the image is automatically adjusted based on forcing the spot you clicked
to become white, and the results are immediately evident on the After
image. If necessary, click the button again to cancel the adjustment.
The Black Pointer and Gray Pointer perform the same function, but your
second click should be on an area that should be black for the Black
Pointer or an area that should be gray (also referred to as neutral) for the
gray Pointer. With all three buttons, do not click a dark shadow or a bright
highlight or an overexposed area.
Once you click on the image, the button remains down, an indication that
you have performed that particular color balance.
You can also double-click on the Black or White pointer buttons to display
a dialog window in which you can define numeric values for black or white.
For example, if you know that the value 230 should indeed be white, you
can double-click on the White Pointer button and enter 230 in the dialog
box.
Let's explain how this button works in conjunction with the Auto Balance
button.
First, Auto Balance is turned on (the button is down) automatically for
a Film Type of color Negative or B&W, and is turned off (the button is
up) automatically for a Film Type of Reversal. However, you can then
turn Auto Balance off or on manually if you wish.
Now, you can use any of the three click balance buttons while Auto
Balance is either on or off. If Auto Balance is on, the results of each
click balance button is "added" to the existing effect of the Auto Bal-
ance button. However, while Auto Balance is off, just the result of your
action with each click balance button is applied.
