In PhotoShop you can create halftone effects (like the background of the type behind the word halftone in the image above) in just few steps with the help of the Bitmap Image Mode. This effect is very popular because it confuses and mesmerizes your eyes if used with enough contrast.
First create an object that you gonna use as your base for your halftone effect. Use the grayscale image mode at this stage. Try bulky typefaces or simple shapes to achieve the best effect.
