The Black & White adjustment lets you convert a color image to grayscale
while maintaining full control over how individual colors are converted. You can
also tint the grayscale by applying a color tone to the image, for example to
create a sepia effect. Black & White functions like the Channel Mixer, which
also converts color images to monochrome while allowing you to adjust color
channel input.
For a video on converting color images to black & white, see

.
Do one of the following:
Click the Black & White icon
or a Black & White preset in the Adjustments panel.
Choose Layer > New Adjustment Layer > Black & White. In the New
Layer dialog box, type a name for the adjustment layer and then click OK.
Photoshop applies a default grayscale conversion.
Note: You can also choose Image
> Adjustments > Black & White. But keep in mind that this method makes
direct adjustments to the image layer and discards image information.
In the Adjustments panel, manually adjust the
conversion using the color sliders, apply an Auto conversion, or select a
previously saved custom mix.
Preset menu
Select a predefined grayscale
mix or a previously saved mix. To save a mix, choose Save Black & White
Preset from the panel menu.
Auto
Sets a grayscale mix based on
the color values of the images, maximizing the distribution of gray values. The
Auto mix often produces excellent results, or can be used as the starting point
for tweaking gray values using the color sliders.
Color Sliders
Adjust the gray tones of
specific colors in an image. Drag a slider left to darken or right to lighten
the gray tones of an image’s original color.
To adjust a particular color component, select the On-image adjustment
tool
and then click
in the image. Drag left or right to modify the color slider for the predominant
color at that -
