How To Fix Filter Gallery Not Working In Photoshop
To fix the Filter Gallery not working in Photoshop, first ensure that your image is in a compatible color mode, such as RGB or CMYK, as the Filter Gallery does not work with bitmap or indexed images. If you're using adjustment layers, rasterize those layers before applying filters.
Check if the layers are locked; unlock them to allow filtering. Additionally, verify that you have the latest version of Photoshop installed, as updates often fix bugs. If the problem persists, resetting Photoshop’s preferences by holding Shift + Alt + Ctrl (Windows) or Shift + Option + Command (Mac) while starting the application may resolve the issue. Lastly, consider restarting your computer to refresh system resources.
