Combines a silver TriGrip reflector with a white/black/grey side like the XpoBalance. The white/black/grey side of the Tribalance allows the photographer to set exposure for the highlights/shadows/midtones of any scene, either before or after the exposure. Just include a shot of the XpoBalance in each lighting situation and then use the black/white/grey side with the Photoshop dropper tool to adjust for shadows/highlights/midtones as required in Levels.
