Can anybody help, please?
Using a 250 Joule Elinchrom studio flash with N D200 all is well using a pc sync lead. Direct flash with reflector gives f/22 at ISO 100 at about a metre. ok.
When I try to use the Elinchrom inbuilt slave sensor, with nothing else changed,(no lead) the flash fires but the illumination reduces by 4 to 5 stops.
Synchronisation? Yes, the whole frame is evenly illuminated. Sync is 250th sec. I think Elinchrom duration is about 800th sec
I've been through the camera manual. The camera 'preflash' is turned off. The problem exists whether the camera's inbuilt flash is used to trigger the Elinchrom or a N SB600. I've tried with/without 'rear curtain' setting.
I'm doing something silly, aren't I? Same effect with 2 D200s, and D40 (D40 has no pc socket, so alave only)
The Elinchrom is 'dumb', ie no auto anything on flash output, fully manual. Output can be reduced 2 stops by a slider - manual. AC 230V powered, of course. I just have the one Elinchrom, can't try another.
Obviously I can work around this, but it's bugging me.
? ? ? ?
Thanks in anticipation!
