| p.1 #2 · Anyway to Get High Speed Sync with YN-622N and AB800's |
Is there any way to set up a YN-622N to acheive High Speed Sync (HSS, FP Flash, whatever you want to call it) with AB800's?
No, because the AB800 isn't capable of HSS.
The way HSS works is to rapidly pulse a Speedlite so that the subject is lit during the entire time the shutter slit traverses the camera's sensor, which is typically in the neighborhood of 1/300 second.
Strobes can sometimes be used at higher than sync speeds by adjusting the timing so that they fire just before the shutter opens, and the shutter slit then moves during the tail-off of the strobe's power curve, but it's not quite the same as true High Speed Sync.
Pocket Wizard calls their sync timing adjustment "Hyper Sync." You may be able to use the YN-622 in a similar manner by setting it to HSS/FP mode and then experimenting with different power levels to find one that has the least shutter shadow. (With the Alien Bees and most other strobes, the lower the power the longer the duration, which is what you need. With Einsteins and Speedlites/Speedlights it's the opposite, which makes them less practical for this kind of hack.)
