Table Of Contents
Tabs. You can make a curve adjustment to all
channels equally or to an individual channel (such
as to blue to emphasize the sky).
Sliders. At the bottom, there are sliders that let you
adjust black and white points of the histogram (the
leftmost and rightmost sliders), as well as the middle
bend of the curve (the central slider).
Points. You can add up to 10 control points. Drag
up to add contrast to an area and down to lighten
the area. Multiple points can be employed for
contrast adjustments based on tonal range.
Most users will either use Curves a lot or they won’t use it at all. The Curves interface is a
bit complex and allows for up to 10 control points. This can significantly open up more
options when adjusting color and exposure. The primary advantage of Curves is that you
have precise control over which points get mapped for tonal adjustment.
