The BounceLite is designed to easily lock in place over almost any commercially available flash. Once there, it serves triple duty as not just a diffuser/softbox, but also flash bounce, as well as for applying filters. Even fully closed, the removable diffuser plastic will serve to soften the harsh lights of a strobe. But once you start to play with the bounce door is when the BounceLite gets really interesting. Since it can be easily locked to a variety of different angles, you can use it to precisely control your flash for specific lighting effects.
