The Black and White adjustment in Photoshop converts a color photograph into a grayscale image. It provides more control than simply removing color because you can adjust how different original colors appear in the final black and white image.
A Black and White effect removes the visible color from an image and represents it using different shades of gray.
The image contains black, white and many gray tones instead of its original colors.
Black and white photography can create a simple, classic and dramatic appearance.
You can open the Black & White adjustment from the Image menu.
Image → Adjustments → Black & WhiteYou can also create a Black & White Adjustment Layer from the Adjustments panel or Layers panel.
The Black & White adjustment provides several sliders for controlling how original colors are converted into grayscale.
Common color sliders include:
When a color photograph is converted to black and white, each original color is represented by a gray value.

Gray ValueThe sliders allow you to control the brightness of these grayscale areas.
The Reds slider controls how areas that originally contain red colors appear in the black and white image.
Moving the slider can make red areas appear lighter or darker.
The Yellows slider controls the grayscale brightness of areas that originally contain yellow.
This can be useful for controlling skin tones and bright natural areas in photographs.
The Greens slider controls areas that originally contain green colors.
It can be useful when converting photographs containing grass, trees and plants.
The Cyans slider controls the grayscale appearance of areas that originally contain cyan.
It can affect parts of skies, water and other cyan-colored objects.
The Blues slider controls how blue areas are converted into grayscale.
It can be particularly useful for controlling skies and water in landscape photographs.
The Magentas slider controls areas that originally contain magenta colors.
It can be useful for photographs and designs containing pink, purple or magenta elements.
One of the most useful features of the Black & White adjustment is controlling the brightness of individual color ranges.
For example, you can make a blue sky darker while keeping other areas relatively bright.
Black and white effects are commonly used for portrait photography.
Carefully adjusting Reds and Yellows can help control the appearance of skin tones after conversion.
Black and white conversion can give landscape photographs a dramatic appearance.
The Blues slider can be used to control the appearance of the sky, while Greens can affect vegetation.
Architecture can look very effective in black and white because the effect emphasizes lines, shapes, textures and contrast.
It is useful for buildings, bridges, interiors and structural photography.
A black and white effect can be used for creative product presentations.
However, if the product's actual color is important, keep the original color version available.
A Black & White Adjustment Layer allows you to convert an image without permanently changing the original image layer.

This makes it possible to create selective color effects.

This can be created using a Black & White Adjustment Layer and a layer mask.
Suppose a photograph contains a red flower and you want the flower to remain colored while the background becomes black and white.
The Black & White adjustment includes a Tint option that can add a single color tone to the grayscale image.
This can create effects similar to sepia or other monochromatic color styles.

Converting an image to Grayscale mode is different from applying a Black & White Adjustment Layer.
A Black & White Adjustment Layer keeps the document workflow more flexible because the original image can remain available below the adjustment.
Practice the Black & White adjustment with a photograph:
Create a dramatic black and white portrait poster.

To create a dramatic black and white photograph, pay attention to the relationship between dark and bright areas.
A black and white photograph can be combined with a subtle tint to create a vintage appearance.

The Black & White adjustment is a powerful way to convert color photographs into grayscale images while maintaining control over how different colors appear.
The Reds, Yellows, Greens, Cyans, Blues and Magentas sliders let you control the brightness of different original color ranges.
Adjustment Layers and layer masks make it possible to create flexible black and white effects, including selective color, dramatic portraits and creative poster designs.
