Using an image as a halftone dot
A grayscale image can be used to make a halftone dot pattern and it then can be applied to a photo.
- Choose the image that will have the halftone applied to it. A simple design works best.
- Reduce the image or selection area to make a "dot" the size desired for the final image. For example: an image that is 75 pixels wide would make 8 dots per inch for a 600 pixel wide image. Use Image > Image Size to change the entire image.
- Surround the small area with the Rectangle Selection Tool.
- Choose Edit > Define Pattern. Give it a name and press OK.
- Halftone the large image by choosing Image > Mode > Bitmap. (If the image is in color then first choose Image > Mode > Grayscale first).
- For Method, choose Custom Pattern and then choose the pattern that was saved earlier from the pop up menu in the Pattern Presets library.
- Enter an Output Resolution. The amount entered will determine how small the halftone dot will be in the final image. The higher the number, the more dots.
