Make sure that the Set white point eyedropper is still selected, and click on the color
sampler you just placed. By clicking on the color sampler you dei ned this area of the
image as the lightest point on the tone curve; it is adjusted to your newly dei ned
highlight color values.
If this gives you unexpected results, you might have missed the color sampler. You can undo by
pressing Ctrl+Z (Windows) or Command+Z (Mac OS), and then try clicking on the white area
of the l ame again. Keep in mind that the color sample that you dropped is only a marker; you
do not have to move the sampler to change the highlight.
Now you will set the black, or darkest, part of your image.
