Profoto 傘背板 (中型)

I used this backpanel to convert my shoot-through umbrella into a more controlled softbox-like light modifier, and the black outer fabric really killed any stray spill. It snapped on securely in under a minute, and the white inner surface kept the output smooth and even.

The white inner surface bounces light back through the umbrella far more evenly than my old shoot-through setup, and the black outer layer kills spill so cleanly I barely need flags behind it. Snaps on in under a minute once you’ve done it once.

The black outer fabric completely blocks spill light, which cleaned up the background in my studio shots. It snaps on easily and stays secure even when I tilt the umbrella.
