They call it FP mode as an homage to the days of flash bulbs. Of course their digital pro models (E1 and E3) also have it. Basically the flash keeps on firing in very short bursts so fast that sensor (or film) reads it as one long burst.Clydehttps://www.blogger.com/profile/07698058435645604902noreply@blogger.comtag:blogger.com,1999:blog-17534827.post-32449980997441535932008-11-05T21:14:00.000-05:002008-11-05T21:14:00.000-05:00Great tutorial and web site, but I still don't...Great tutorial and web site, but I still don't understand how the camara & flash do it. If the flash were just "staying on" during the exposure, then the faster shutter speed would darken both the sky and the model. Since that obviously didn't happen, then the flash must still be flashing in synch with the shutter. The f-stop is controlling the flash exposure while f-stop & shutter speed together are controlling the ambient - just like the normal flash / ambient balancing process. Even with the faster shutter speed, the flash is still a shorter duration than the exposure time on the sensor. I guess I need to dig out the manual.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-17534827.post-70635844372197638262008-11-04T14:19:00.000-05:002008-11-04T14:19:00.000-05:00Hi David, I use high speed sync all the time, but ...Hi David, I use high speed sync all the time, but being nerdy, i was wondering about those photons. Can you explain how the photon (energy) system of a flash operates? thanks, and btw, just got back to Columbus from shooting a wedding in Cincinnati. Lots of fun!

Didn't we use this feature even with film SLRs (not speaking about FP, even my old Maxxum 9 does HSS).<BR/>Funny that obviously so many photogs have not discovered this feature.Anonymousnoreply@blogger.com
