The answer is, manipulate two image adjustments. That simple? Yes. You can make a stencil effect in Photoshop by adjusting the levels of Threshold and Posterize.
I’ve been working as a graphic designer for more than ten years. I have to say that this is my favorite method to turn an image into a graphic-style design because I can simply move the sliders and get different effects.
Not being lazy, just want to share with you the good stuff. In this tutorial, I’ll show you this quick and simple way to turn a photo into a stencil in Photoshop.
Note: the screenshots are taken from the Adobe Photoshop CC Mac version. Windows and other versions can look different.
Step 1: Open the photo in Photoshop.
Step 2: Select the Background and hit Command + J on the keyboard to duplicate the background layer.
Step 3: With Layer 1 selected, go to the top menu Image > Adjustments > Posterize.
When you move the slider to the left, the image has fewer details. For example, it would look something like this if you set the Levels to 3.
Vice versa, the image will look more like the original photo when you increase the levels by moving the slider to the right.
Depending on what you need, adjust the level accordingly, usually, around 10 is a pretty good point. I’ll just set mine to 10.
Step 4: Go back to the top menu and select Image > Adjustments > Threshold. When you move the slider left, the image shows more details of the white areas.
You already know what’s going to happen when increasing the Threshold Level. That’s right, the image shows more black areas and loses details of the white areas.
Depending on the effect you are trying to create, adjust accordingly. I’ll set mine to 100.
Paint on the background to remove unwanted white areas.
It really only takes five quick steps to make a stencil from an image in Photoshop and you can adjust the levels to get different effects.
I have found that the key to turning a photo into a stencil is the suitability of the original image. If the original image has high contrast, sometimes it’s hard to get a perfect point, too dark or too light, but with practice, you’ll get there.About June
