Thanks for all the advice, guys! So what I ended up doing was asking some random guest that had an dSLR (cuz there's ALWAYS at least a handful at every wedding) and he gave me a reading of 1" at f/6.3... So I'm like.. CRAP... So now the finger counting goes... counting down how many from 5.6 to get to f/2 (I have a collapsible 'Cron) and then adjusting my shutter speed accordingly... I ended up shooting most of the wedding at 1/60 at f/2 a handful of shots were done in 1/30 when the lights were dimmed a bit... I'm thinking that might have been a little on the dark side... So I was thinking about having the developer push it 1 stop up so that I can get at least brighter pictures rather than darker ones.. I think I have a TMax 400 in there... That should be okay, right??
But I think i have about 7 shots left on the roll, I'll definitely scan them in once I get it developed.. I'm pretty excited to see how it turns out.. At this point what I'm afraid of is shooting at a slow speed, are any blurry movement shots that might have occured.. Although I tried not even going for those shots, knowing I wouldnt be able to handle them.
