How to Create a Halftone Effect in Photoshop

Graphic designers are always looking for an unique way to present their graphics, and one eye-catching effect is to convert the image into a halftone. A halftone uses a series of alternating dots to create the image. Adobe Photoshop allows you to create a halftone effect using two different methods: converting the image into a halftone bitmap or using the halftone pattern filter. Use the Photoshop halftone effect to differentiate your graphic design style and make your images more eye-catching.

The Bitmap Halftone Method

Step

Open Adobe Photoshop. Click "File" from the top navigation menu and select "Open" from the drop-down menu. Click the picture you want to convert into a halftone and click the "Open" button to open the image in the Photoshop workspace.

Step

Left click "Image" from the top navigation menu and roll the cursor over "Mode" to open the "Mode" drop-down menu. Click "Grayscale" and click the "Discard" button on the resulting message window to convert the image to black and white.

Step

Click "Image" and roll the cursor over the "Mode" option. Click "Bitmap" from the resulting drop-down menu. Click on "Halftone Screen..." from the method drop-down list in the bitmap menu. Click the "OK" button to save changes.

Step

Type "8" in the "Frequency" field to make the halftone dots 8 lines per inch, for example. Type "45" in the "Angle" field to spread the dots at a 45 degree angle, again for example. Click "Round" from the "Shape" drop-down list. Click "OK" to save your changes and convert the image to a halftone bitmap.

The Halftone Pattern Filter Method

Step

Double click on the Adobe Photoshop icon on your computer to open Photoshop. Press and hold the "Ctrl" key on your keyboard and press the "O" key to start the "Open" image dialogue window. Click on the image you want to convert into a halftone pattern and press "Open" to open the image in Photoshop.

Step

Click "Filter" from the top navigation menu and roll your cursor over the "Sketch" option. Click "Halftone Pattern..." from the resulting drop-down menu.

Step

Click and drag the "Size" selector to the number 3, for example. Click and drag the "Contrast" selector to the number 13, again for example. Click the "Pattern Type" drop-down menu and click "Dot" from the drop-down list. Click "OK" at the upper right of the "Halftone Pattern" window to apply the filter.
