I'm trying to do a shot similar to this. I looked in the SB800 manual and read the two pages about the RPT mode twice and it still doesn't make much sense, but I thought I'd give it a try anyways.
I started by putting the flash on RPT mode. Once there, I hit the red "flash" button on the flash to test it. It worked fine. I saw 5 bursts of light.
Then when trying to test it using my Cybersyncs, it would not fire the 5 flashes, but instead, just one flash. Is this RPT mode only applicable when the camera is mounted to the camera's hot shoe?
Since I couldn't get it to work with the Cybersyncs, I decided to mount the flash to the camera. Once I did that I also only got one flash. This initial attempt was at 1/80th of a second, which is the same shutter speed used in the attached pic (which I downloaded because I wanted to try this method, it is not my pic). At 1/80 I still didn't get my 5 flashes again. So I increased the shutter speed to 1.5 seconds just to see what would happen, and then I finally got my 5 different flashes. But they were all very fast and not spread out through out the 1.5 second exposure.
I played with adjusting the shutter speed some more and never got the results I wanted. Does anyone have any idea specifically how a shot like the one attached would be taken? Would it matter if I had it on front or rear curtain?
Thanks for any help anyone can provide. I'm determined to get this type of shot figured out.
