Sometimes, not everyone can make it.

With group shots, sometimes it is impossible or impractical to get all subjects together. 
With some planning, it is possible to create group shots that seamlessly combine people who were there at difference times.
Here is an example of one group shot combination.

A BIG GROUP LIT WITH SPEEDLIGHTS

Client: Daimler

I was asked to shoot a large group shot at a conference and supply prints for every attendee by the end of the day. There wasn’t a chance to so a site recci but I was told there was a large open area that would probably be suitable.

A pet hate of mine is seeing large group shots lit by lights (usually soft boxes) either side of the camera so the area is flooded by light. This is a safe option, but not very flattering for the group.

I always look for how can a accomplish a soft light, falling off from one side of the subject to the other with a good balance. On this job, I needed to have 5 speedlights aimed towards the ceiling to the left of camera, 2 speed lights through my interfit softbox, I  used the ambient for fill and had a speedlight lighting the ceiling behind the group to add some tone.
