I have been 'volunteered' to take some shots at a very important event. (I didn't know that the word NO had been expunged from the dictionary!)
It will require some informal groups of between 2 and 12 people, some award presentation shots, and so forth. I am not sure how close I can get for the latter if I have to do it in real time.
The last time I did this I nearly gave up photography because I could not get into the venue before the event and I ended up with an angled ceiling about 20 feet up. So no bounce flash! I tried a diffuser but the results were little better than direct flash. Doesn't a flash gun take a long time to recharge!
Also I could not get my A700 to focus properly where there were two people in the frame (3~4 foot apart at distance 15~20 feet), depth of field was not good anyway but it kept focussing for the middle. I tried spot focus - hold - take, too!
Where it did work photos were messed up by the pop up display boards that have company logos on as they suddenly became like mirrors! I can't post an example because of some privacy issues re the subjects.
But the nightmare has returned!
Since that event I have acquired a 28-75mm Tamron f2.8 which I think I shall use and /or a Minolta 24mm f2.8 if it arrives in time.
I have an HVL-42AM flash gun, Stofen diffuser, and off-camera cable & flash bracket.
Suggestions for settings please.
