Backdrop HDRI

[waters]

I use a backdrop to photograph my custom furniture. For KeyShot rendering purposes I would like have an HDRI shot of the backdrop. I use Oloneo for my HDR work and would appreciate some feedback on setting up for the HDRI shot. I can bracket three images with my D7000 @ + 2 stops over, metered, and - 2 stops under, but I think I will need more latitude than that.
Thanks

Without a remote to program more stops you will need to manually control your brackets. Try setting the bracketing to +/-1 stop, then do three sets of brackets at manually controlled exposure starting points. Start at -3 stops, then 0, then +3.
