I'm new to the subject of studio flash.  I have two strobes rated at 220
watt seconds each but they didn't really come with instructions for a novice
such as myself.  They mentioned a guide number of 165 and said for example
that if the subject is 10 feet away then divide 165 by 10 to arrive at an f
stop of 16.5.  Simple enough.  But I have two strobes.  Surely that affects
things.  I have shot several rolls of film that have not produced any
consistent results.  Several questions:
I assume I will need to buy a flash meter.  Looking at these I see that you
fire a test flash at the meter and it gives you an appropriate f stop which
is great but what would be the shutter speed?  The sync speed on my Pentax
645NII is 1/60 but how does the flash meter know that?  And what if I used a
different shutter speed?
Any suggestions on a simple yet inexpensive flash meter?  I see some of them
cost more than many cameras!
I have a Pentax 645NII.  I need a hot shoe adaptor to connect to the
strobes.  Any suggestions?
Thanks in advance for any help.
