Look for Contrast, Shape and Texture
By shooting in black and white, you can remove the distraction of color. That means there’s more focus put on other aspects of your photography. That can include things like the subject, shapes, textures, lighting, contrast, and composition.
This makes black and white photography ideal when you’re experimenting with different types of photography. It’s also useful when you want as much attention as possible on a particular element in your photo.
Follow these steps in order:
Open Adobe Photoshop.
Click File in the top menu.
Select Open.
Find and select the photo you want to edit.
Click Open.
Your photo will appear in the Photoshop workspace.
Look at the Layers panel on the right side of the screen.
At the bottom of the Layers panel, click the half-filled circle icon (Create new fill or adjustment layer).
Select Black & White.
Photoshop will automatically create a new Black & White adjustment layer above your photo.
Your photo will now appear in black and white.
In the Properties panel, you can adjust the individual color sliders (Reds, Yellows, Greens, Cyans, Blues, and Magentas) to control how light or dark those areas appear in the black-and-white image.
Go back to the bottom of the Layers panel.
Click the half-filled circle icon again.
Select Levels.
A new Levels adjustment layer will appear above the Black & White layer.
In the Properties panel, you'll see a histogram with three main sliders:
Black point — controls the darkest areas.
Midtone/gray slider — controls the brightness of the middle tones.
White point — controls the brightest areas.
Move the black slider toward the beginning of the histogram to deepen the shadows.
Move the white slider toward the end of the histogram to brighten the highlights.
Adjust the gray/midtone slider to make the image lighter or darker overall.
Stop when you have good contrast while still retaining detail in the shadows and highlights.
Keep the Levels and Black & White as adjustment layers rather than permanently changing the photo. This lets you go back and modify the adjustments later.
