Creating Censorship Effects in Photoshop
Censorship effects are widely used in the field of journalism. When posting sensitive images, publishers often censor faces or specific areas to avoid evoking negative emotions in viewers.
No matter your intention, you can achieve censorship effects using Photoshop with the steps below.

4. Draw around the area you want to blur, for instance, I'll take the example of the girl's face.

5. Hold Shift to add another area, such as the boy's face.

Now that we've selected the object to blur, let's move on to the next step.
Step 2: Masking the Selected Area
It's time to pixelate the selected areas using a simple process, utilizing the Pixelate >> Mosaic features in Photoshop.
