Halftone Effect

Converting a normal (RGB or Grayscale) photo into a Bitmap (halftone) image is very interesting and gives a unique and dramatic effect. Unknown to many, halftone is a popular form of digital art which can be seen in comic books, magazines, newspapers, and other media. It is characterized by dotted figures basically in black and white and gray. This tutorial is largely inspired by the works of Roy Lichtenstein, a famous pop artist.

The following guides you through a 3-step instruction to achieve the expected result which can be done so easily, even a newbie find it a ‘no sweat’ stuff.

Photo used here is Scarlett Johansson.

Open the photo you wish to edit. By default, this become your ‘Background’ layer as displayed in your layers palette.

Most probably you’re in RGB mode and we can’t effect a halftone right away. To be able to do such effect, first, we must convert our image into grayscale (Image>Mode>Grayscale…).

Next, convert grayscale into bitmap (Image>Mode>Bitmap…).Under Bitmap, you may select the default values and press Ok.

Enter a lower value if you want the effect bigger and higher if smaller (dot distribution). Voila, you have your halftone effect!

Note: Before you can proceed to the next step, convert back the image into grayscale, then to RGB.

If you wish to colorize, go on and apply Hue/Saturation. Play on the sliders to select the color you want, or, you may just check Colorize for an instant color.

This is the result:
