The
Black & White command 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.
Choose Image > Adjustments >
Black & White. Photoshop performs a default grayscale conversion
based on the color mix in the image.
Manually adjust the conversion using the color sliders,
apply an Auto conversion, or select a previously saved custom mix.
Preset
Select a predefined grayscale mix or a previously saved
mix. To save a mix, choose Save Preset from the palette menu.
Auto
Sets a grayscale mix based on the image’s color values,
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.
The grayscale ramps
show how dark a color component will become in the grayscale conversion.
The mouse pointer changes to an eyedropper as you move it
over the image. Click and hold on an image area to highlight the
color chip for the predominant color at that location. Click and
drag to shift the color slider for that color, making it darker
or brighter in the image. Click and release to highlight the text box
for the selected slider.
Alt-click (Windows) or Option-click (Mac OS) a color
chip to reset an individual slider to its initial setting. Press
Alt (Windows) or Option (Mac OS) to turn the Cancel button
to Reset, which resets all color sliders.
Preview
Deselect to view the image in its original color mode.
To apply a color tone to the grayscale, select the Tint
option and adjust the Hue and Saturation sliders as needed. The
Hue slider changes the tint color, the Saturation slider makes the
color more or less concentrated. Click the color chip to open the
Color Picker and further fine tune the tint color.
