I have been experimenting with using the SB-700 speedlight off camera. Quite fun actually, but I encountered one problem now and would like to see if anyone had any thoughts.
The way it works is that the SB-700 can be used as a remote and the flash on the camera acts as commander unit. You can choose various schemes in the D7000. E.g. the fixed on camera flash participates (as TTL/manual/--) or (and this is what my question is about) it acts as commander only, but doesn't provode flashlight to the photo (the -- mode).
What it does in this case is emit a pre-flash, just before the photo is taken, to alert the SB-700. Works perfectly, but...
But...when you photograph a person the pre-flash is still blinding him/her and the effect in the final photo is that his eyes are partly closed when the actual photo is taken. The SB-700 can be on the side (or wherever you want) and shouldn't blind the subject, the problem is with the pre-flash from the on camera flash unit.
The problem would be solved if I used a transmitter (or a cable), but I don't want to spend money on a transmitter and the cable would make me less flexible.
My idea is that I might construct a small paper box that would direct the light from the on camera flash upward or something. The SB-700 would still see it I suppose, but the subject wouldn't get blinded anymore.
Any other ideas for this?
