By using the TW-B Two-Way Bounce Unit from Sto-Fen with your on-camera flash unit, photographers will be able to throw some light forward while still using the flash as a bounce lighting source. This helps create catchlights in your subject's eyes and works to provide some fill. This unit is attached to the flash head using a dedicated adapter mount that slides on without the need to additional adhesive. This mount can be reversed for using the bounce unit as a shoot-through panel as well. Additionally, it comes with a mini panel for use as a kicker light.
