Ever wondered about those digital effects in advertisements having some parts in pixels? Let's try it. Open Photoshop and take a picture. Duplicate its layer and on the new layer,select it and go to filters->pixelate->mosaic. Then you can mask the new layer with having some parts in blur and the other one's in focus or can use gradient. You can lighten or darken the mask layer for better output. This helps in creating unique styles and digitize your world.
