Have you ever seen one of those images that seem to be made of little colored dots? It’s a technique that’s been widely used in pop art and, more recently, advertising. Now, guess what? You can apply that same dot effect to your photos in no time. Simply launch Photoshop and follow these easy steps.
1. Open up your photo and duplicate the background layer. Name the first layer as “original” and the one you just duplicated as “dots”.
2. Now make sure your background color is black and your foreground color is white, and click on Filter > Sketch > Halftone Pattern. Set Size to 1, Contrast to 5 and Pattern Type to Dot, and click on OK. You’ll get something like this:
3. Now it’s time to invert colors. Press Ctrl+I and your image will become something like this:
4. Finally change the “dots” layer blending mode to Linear Light and you’re done! You may also try different opacity values and see how they affect the final result.
