Yo u c an u se au tom at ic c ol or c orr ec tio n t o a dj u st t he co nt r ast (s et a cc u-
rate blacks and whites) and to balance the color channels (remove color
casts). Both of these corrections usually improve the sharpness and detail
of the image. And because the human eye is extremely sensitive to accu-
rate blacks and whites—in terms of both luma and chroma balance—these
simple changes also do a great deal to improve the image aesthetically.
The automatic color correction functions within the HSL group are shown
in the following figure.
Removes color
cast from shadows

(whites)

Auto White sets white values
Auto Balance removes

Auto Contrast sets black and

NOTE One popular
workflow is to expand
the Dual Split view to
display the entire frame
and then toggle the Dual
Split button to display
a complete “before and
after” comparison of the
whole image.
