Simplicity is often the best way to go. The Flashpoint Flash Diffuser, which is virtually the same as the Sto-Fen Omni Boucne (but costs a bit less), is a simple plastic box that fits over specific flash units.
Snap the Flashpoint Flash Diffuser onto your swivel head flash, which is pointed upwards and towards your subject, to achieve the kind of wide-open lighting that barebulb flash can give.
True, it’s nothing fancy. It snaps on your flash and you’re ready to go. You won’t be able to control color balance with it—although it is designed for daylight balance, just like your flash. And you can’t collapse it. But it only costs $15, and it diffuses the light. ‘Nuff said.
