How can I achieve a comic book halftone effect in post-processing?

Several methods exist. Photoshop offers filters like 'Noise' (set to Uniform and Monochromatic) and 'Reduce Color' which can simulate halftone patterns. Alternatively, you can find halftone texture overlays online and blend them into your image using blending modes like Multiply or Overlay. Experiment with different dot sizes and frequencies to achieve the desired look.
