To use plug-ins compatible with Adobe Photoshop (8bf plug-ins) within Zoner Photo Studio, use the Editor's Plug-ins menu. Plug-ins are external picture processing "filters"—functions—that you can use on the current picture.
Zoner Photo Studio does not include these plug-ins, but both free and commercial plug-ins are available on the Web. To find free plug-ins on the Web, do a Web search for e.g. "free 8bf."
