Yes, it's an earlier version of the Better Beamer that was made by Kalt. I had the flash comp set at -1, but probably should have been at -2, as Mark Cassino suggested. I think the stop was f8, with the shutter at 1/500th. I have to use hi-speed synch for handheld shooting like this. That in itself is somewhat iffy. But this was a valuable exercise. As I mentioned previously, I have since discovered that this particular shot is slightly out of focus. My bad for not checking it at 100% when doing the RAW conversion.
