The internal flash triggers the external with minimum power.
FYI - I think c_joerg is referring to using the CHDK Manual Flash Power Setting and something like this : SYK-3 Sensor
Hello,This is for working with Chdkptp and (not exclusively) the multicam.lua script. Would it be possible to program an Arduino to be seen by Chdkptp as another canon camera. The arduino would not have to implement every function, but it would respond properly to the shoot command, and it could create a trigger pulse to fire a flash unit.
Finally, multicam.lua sync only has a precision of a few tens of milliseconds
I was reading through all the all threads about syncing multiple cameras, I was under the impression that using init_sync() and shoot() are now very accurate. I read that the camera itself operates in 10millisecond ticks, and I tried to follow the multicam.lua script - since the script uses min_sync_delay, doesn't that mean that all the cameras would shoot at the same tick, and the same tick could cover a 10 ms span over all the cameras?
is !mc:shoot{opts} the way to get the best sync? I initially started with shoot_hook_sync, but couldn't find a way to set exposure time and iso, and then came to the conclusion that it's special features had been folded into the regular mc:shoot - is this correct or not?
it seems like if you wanted precise timing, then hardware remote with chdk is the only way to do it, even spending a lot of money of DSLRs wouldn't help you.
