Сurves
One of the most powerful tools for adjusting tones to brighten, darken, add contrast and shift
colors. Curves can usually be applied to all channels together in an image, or to each channel
individually. Curves can help you manually fine-tune the brightness and contrast of the image.

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.

• 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.
