How do I remove halftone from a photo?
Drag the “Radius” slider right, observing the canvas or the dialog's Preview window as you do so. Stop dragging when the dots of the halftone pattern become indistinguishable from one another. Click "OK" to close the Gaussian Blur dialog box. The halftone pattern is gone, but some image detail is also.
How do you vectorize a halftone in Illustrator?
To create vector halftones with Adobe Illustrator, we'll have to trace over the rasterized image using the Image Trace feature. Select the image and navigate to Object > Expand Appearance. Then, navigate to Object > Image Trace > Make and Expand. This will create a vector tracing of your halftone pattern.
