Hi,

I may sound silly (sorry, I'm not fond of flashes), but what about using the SU-800 wireless controller ?
I know that higher range cameras have the ability to wirelessly control several flashes without any external device. Tried once... it works...

Just my 2 cents.

no doubt it is difficult to do -- but multiple Canon Speedlights can be wired together in parallel with no ill effects (presumably because 100% of the calculation happens inside the CAMERA not the flase?). For some reason, Nikon must be using the control channel to get some exposure info back from the flash itself -- which would then cause probs with multiple flashes on the same channel.

Hi , all ,
Thanks to great work by lain in this post : viewtopic.php?f=2&t=1575&start=20#p9962 ,
codes for front and rear curtain firing are located , got small progress on high speed flash sync , but still long way
to go .
1)insert action after front curtain fires and before rear curtain fires .
2)action in 1) triggers SpeedLight N times
3)the SpeedLight fires with 1/N of total flashing power each time it's triggered .

Since huge amount coding , so C programming for TMP19 is must have , i think that TOSHIBA IDE is a very nice tool ,
but how to get a FREE TOSHIBA IDE ?

Best reagrds,
Leegong
