Light Tent/Nikon CLS Reflection Question

[BLBJBranch]

All,
I made a DIY light tent this week and was experimenting with various subjects using Nikon CLS. I have 3 SB-600s (left, right, top) and was getting pretty good results. I was happy how they turned out...except for one thing.

My on-board flash was casting reflections on reflective subjects (wine glasses, bottles, etc.), even though it was set to "--".

Does anyone have any tips to keep the on-camera master from reflecting? It just occurred to me as I was typing to make kind of a hanging barn door to block the light, but I don't know if that would block the signal to the speedlights.

Any ideas?

Thanks.

You can get something like this: 4905 Nikon SG-31R Replacement IR Panel for the Built-in Flash on the D200, D70s or D70 Digital Cameras.

Nikon actually makes a piece that blocks the light and lets the signal through.

Nicole,
Thank you very much. I think I'll order it tonight.

I have one: it's useful in certain circumstances, but when you're not shooting things up close, it can be a hindrance.
