get a tripod, set your camera height at the eye level of the second row people.
use 50mm lens if you are using full frame body, 35mm if you are using 1.5x crop body
get a studio mono light 500ws, with a reflective umbrella,
mount it on a very big and tall light stand, you need to let the light taller than the last row people.
set the light just right above your camera, don't bother light spill, you should be more concern to get the exposure is very evenly from left to right, front row to back row.
forget about mixed with ambient light, just use another flash to light the background, unless you can get ambient light at 1/60 with f8, or else if someboby keep moving, you will not able to get any sharp photos.
btw, one light one shadow, two lights two shadows, multiple lights many shadows, and also if one hotshoe flash deliver f4, you need 4 flash to deliver f8, 8 flash to deliver f11.
so it is easier and faster to set up just one mono block.
or you can just simply shoot the group photo in very high ISO with one hotshoe flash
hmm, if lets say i have 3 flashes and the background are just some curtains ( if not they are windows, even worse ).. so i won't need to light the background. should i use the 3rd flash and bounce off ceiling instead? if yes, hide it behind the group or behind my camera? or what can i use it for?
sorry for the lousy diagram - it was pretty hard to adjust them. haha.
i can only make do with my equipment though :
2 stands
3 flashes ( all have equiv. power to 430exII - possible to shoot @ f11, iso400? )
2 shoot-thrus
1 tripod
1 full set of gels
should be around 3 rows of 8 also. relatively small room.
