How do I apply a halftone dot pattern to an image in Photoshop for a comic book look?

To achieve a halftone dot pattern for a comic book aesthetic in Photoshop, duplicate your layer. Go to `Filter > Pixelate > Color Halftone`. Adjust the radius to control the size of the dots. You can also experiment with different channel angles, though default settings often work well for a classic comic look. For more control, convert your layer to a Smart Object before applying the filter. You can then blend this halftone layer with the original image using layer blending modes like Multiply or Screen for interesting effects.
