What's the best way to add a halftone effect to a photo to mimic comic book panels in Photoshop?

To create a halftone effect, start by converting your photo to grayscale. Then, create a new layer above the grayscale layer. Use the Brush Tool with a low opacity (around 10-20%) and a textured brush to paint in black and white dots. Adjust the size and spacing of the dots to achieve the desired comic book look. Finally, apply a Gaussian Blur to the halftone layer to soften the dots and blend them together.
