On or Off-Camera To shoot with the B2 is to shoot with all options at hand. Put the head on a bracket on your camera, the pack on your belt and stay moving. Or put everything on a stand and go off-camera. Shoot with TTL. Or shoot in Hybrid Mode and switch from TTL to manual control with the settings intact. Use it as a subtle fill light. Or crank up the power and take full control of the ambient light. Connect one or two flash heads. Use only the B2. Or sync it with one or several other B1 Off-Camera Flashes. Shoot with a bare head. Or choose from the widest assortment of Light Shaping Tools available and shape the B2’s already beautiful light into any light you can imagine.
