Pixelation occurs when you experience low picture resolution and have the ability to recognize each pixel with the naked eye. Though we do not have the ability to fully eradicate pixelation from a picture, we can lessen the issue. If you learn how to use the various features of Photoshop software, you can reduce pixelation in all of your images.
