Posterize your photos to create artistic effects.
Increase the drama in photos by decreasing the number of colors. With Adobe Photoshop, you can do it in a few clicks.
What is posterization?
The term posterization comes from the process artists once used to turn photos into printed posters. To make mass production possible, they had to reduce the color variation so they could use fewer colors of ink during printing. By changing subtle gradients of many colors into more obvious sections of just a few colors, posterization results in a more painted or airbrushed look.
Try out a new creative approach to photos by posterizing your holiday card or next social media post. Posterize a portrait to make your subject look heroic, or see what happens when you posterize a sunset photo before you share it with your followers.
How to posterize your images in Photoshop.
Whether your original image is a PNG or JPEG, full color or black and white, just follow these steps:
1. Upload the file.
Select the image you want to posterize in Photoshop.
2. Turn your photo into a smart object.
Create a Smart Filter. Select Filter from the top menu and click Convert for Smart Filters. You can add, remove, adjust, or hide Smart Filters, so any edits you make are nondestructive. (This way you can always go back to the original photo and start over.)
3. Posterize.
In the top menu, select Image › Adjustments › Posterize.
4. Select the level of posterization.
A slider window will pop up, where you can select a number between 1 and 255. This describes the number of colors that will appear in each of the color channels. Move the slider to the left to decrease the number of colors and achieve the posterization effect. The human eye tends not to register changes in the numbers above 35, so try selecting a number between 1 and 35.
How to add selective posterization effects.
If you don’t want to apply posterization across your whole image, you can create a mask and apply the filter selectively.
1. Create a mask.
Click the Smart Filters in the Layers panel.
2. Set the brush to black.
Make sure the black square is in front of the white.
3. Paint.
Paint the area you’d like to keep free from the effect.
Another way to selectively posterize is to use the Select Subject tool. Just follow these steps after you’ve created the Smart Filter:
1. Select your subject.
From the top menu, click Select › Subject.
2. Invert the selection.
Click Select › Inverse to apply it to the background.
3. Posterize.
In the top menu, select Image › Adjustments › Posterize.
