Yup. Screw and filter then keyhole!!!! Maygen I CAN'T imagine how you could be at a loss for what to do with a keyhole filter? You can obviously take wedding photos but also children photos. Anything where you want the viewer to feel like they are snooping. If you have a star shape. See if you can adjust the focus of the filters. You may be able to take some nice pictures of people with a blured edge without performing PS post work. Another suggestion. Double Exposure. Just a couple of ideas. Bsteph
