Higher threshold settings mean that a group of pixels must show greater differences in color value before Photoshop's sharpening algorithm can see them as edge pixels.ĭrag the Amount slider right until the canvas or the Preview window in the Unsharp Mask’s dialog box shows a sufficiently sharp image.Ĭlick "OK" to close the dialog box and view the image, which is now free of the halftone pattern. At the end, just add a simple Curves Adjustment Layer to add some contrast. The resampling will help remove some of the apparent blurriness of the image as well. This control lets you set the criteria by which Photoshop determines whether or not a pixel is an edge pixel. Resample the image to your end resolution. Apply higher settings for higher resolution images.ĭrag the Threshold slider to a value between 1 to 5. This is also why something like despeckle doesn't work. That question is about an image that has a repeating pattern 'on top of' it which needs to be removed/filtered out, where in this case the pattern is the image removing it would remove the image. In general, lower resolution images require lower Radius settings. I don't see how to use fourier transforms here. You can adjust it after adjusting the Amount and Threshold controls, if the image doesn’t yet appear sufficiently sharp. The 1.0 value is only an initial setting. The Radius control lets you specify whether Photoshop should include more or fewer pixels surrounding the edge pixels when it performs its sharpening calculations. Click the “Unsharp” item to display the controls for Unsharp Mask.ĭrag the Radius slider to the 1.0 mark to specify a radius of one pixel. The halftone pattern is gone, but some image detail is also.Ĭlick the “Filter” menu, then click the “Sharpen” item to display a list of filters that sharpen imagery. Click "OK" to close the Gaussian Blur dialog box. The overall category would be hidden but I could focus attention on only a few elements in the view that are in. Stop dragging when the dots of the halftone pattern become indistinguishable from one another. When a Category is set to Halftone, I would like the ability to select elements within that category, override the visibility/graphics, and set the selected elements to Fulltone (not sure what the opposite of halftone would be ). Depending on your needs and preferences, you may find that one method works better for you than another.Drag the “Radius” slider right, observing the canvas or the dialog's Preview window as you do so. In general, getting rid of halftone in Photoshop requires some trial and error, and there is no one-size-fits-all solution. The brightness/contrast tool can also be used to remove halftone, but like the curves tool, it can be more difficult to control than the levels tool. The curves tool offers more control over removing halftone, but can be more difficult to use than the levels tool. However, it may not be able to completely remove all traces of it. The levels tool, for example, can be used to quickly and easily remove most instances of halftone. Getting rid of halftone in Photoshop can be done in a few different ways, each with its own set of benefits and drawbacks. Go to Image > Adjustments > Brightness/Contrast and adjust the brightness until the halftone is gone. Go to Image > Adjustments > Curves and adjust the curve until the halftone is gone. Be sure to follow the steps in this guide carefully to avoid any unwanted artifacts in your final image. PRO TIP: If you are not careful, halftone can ruin your image.
