Ok, so lets step back to last week.
I bumped into another wedding photographer at a hotel and he was taking a formal shot indoors, bouncing his flash whilst in program mode.
He saids he uses it for most of his shots...whereas I use manual..or try to, but AV for times when the lighting continuously changes.
Fast forward to this week, I have a wedding tomorrow and some of the formals (the group is only 10 people) concern me. The indoor formals are in a room where the ceiling height is 30ft (10metre dome). I currently only use on camera flash and I'm a bit lost as to what to do in this respect.
Based on another shot I saw taken in similar circumstance the exif stated they use F/3.5 ISO 1600 at 1/15sec on a 450D without flash.
I want to be at 1/60 at least so intend to go to 2.8 with ISO1600.
If I need to use flash I may try program mode for the indoor shots.
What are everybodies thoughts on this?
