(not available
when
grayscale is
selected)
While the brightness slider adjusts brightness
for the image as a whole, the color-balance
sliders (one for each channel in the current
color model) allow the user to adjust bright-
ness for each color individually. For example,
when the RGB color model is selected, drag-
ging the red slider in the + direction bright-
ens the red portions of the image, making the
image as a whole more red. Dragging it in the
– direction dims the red elements in the im-
age, bringing out the remaining colors. Color
balance can also be set by entering values
directly in the text boxes to the right of the
sliders.
