Subject: [OM] Burning OM question
I am positive a listee can answer this. I have also heard the Dr.
Flash's long lost Great Uncle, Dr. F. Bulb, has also recently relocated from
New England to NY state as to be closer to his nephew.
I did find a stash of GE Blue #6 flashbulbs at my Mom's the other day.
Still looking for the Big Berthas.
I have a bracket with 7" reflector--might be trouble mounting an OM though.
I have an odd ball adapter that provides a FB bayonet mount for a standard
light bulb type of screw mount---may plug into a lamp loaded with a FB for
extra effect.
I am thinking that these FB's hooked up to the PC terminal on FP on an
OM-2 and the cam in auto,might constitute a TTL type of metering as the
shutter would just serve to limit the light in lieu of a quench signal. I
think that mode triggers the flash 20msec or so prior to the first curtain
and it is such a long burn I think that syncing at most speeds shouldn't be
an issue.
I have seen a poor scan of the light output curve of the GE #6 and it seems
to reach peak in about 30msec.
It should be way fired up by the first curtain. The shutter speed does
alter the GN, but not in a linear fashion like the F280 as pointed out by
Tim. So, will it work on auto????????
If so, pretty cool--Flash not sufficient it justs drags the shutter to
fill in with ambient.
Too much flash---just a quicker shutter---even OK at faster then
1/60th- assuming it will do that on auto and not just fire at 1/60th with
something plugged into the PC connection. Better get this right early on--I
see replacements are (gulp) $60.00 a dozen on Flashbulbs.com.
All Fired Up, Ready to get in Sync, Mike
