In our daily life, we have noticed different posters here and there. Back in our mind, we think that it would be great if we made a picture like that for ours. This tutorial will discuss “How to Posterize a Photo in Photoshop?” Let’s go for a detailed guideline so that you can do it at home. 

What Do You Mean By Posterizing? 

The popular way to print or display an image with a limited number of color tones will be suggested as a poster. When we rasterize a vector layer, Adobe Photoshop will convert it into pixels. 

Initially, you will not notice the changes. If we zoom into a newly rasterized layer, we will notice that the edges have turned into a tiny square-shaped box. We call them a pixel.
