OK, thanks guys. I will set-up the shot from the same perspective as lobby4. I'm not at all familiar with lighting such a large space, but I will attempt the techniques we discussed above and go for fill -- I just need enough light to shoot at 1/60 f5.6 @ ISO 400. I will also set up the headshots in some part of the lobby instead of the hallway.
What I was originally thinking with the front-on shot (lobby 2, but from a higher vantage point) was that it really was the least inconvenient location and that I might be able to get the reflections to pop out a bit in post for added depth. Something like this:
But it's not great. The idea was to get up high and get more reflection, but the shot is about them and the space, not the reflections, and I don't know what it will look like from up there and I'm more partial to the real depth we get in lobby 4. So I'll go with that and get up on a ladder. Any suggestions on where to position the flash units and how to angle them? Umbrellas?
This is a not-for-profit company with an office on the 5th floor of this twenty-something story building. They had to get permission to shoot in the lobby. The company helps big businesses be more socially responsible. They do things like organize tours with CEO's so the execs can see for themselves the effect their philanthropic efforts are having in the community. I am shooting the job at a reduced rate in exchange for profile on their website and in the newsletter they circulate to the big companies that are members of their organization.
I will follow your advice, Doug, and stay in the lobby rather than have a seperate set-up for headshots on the 5th floor. That will save me some money too as I can use the same lights that I've setup in the lobby (I was thinking of arriving quite early and setting up the two separate scenes so that I knew I had what I needed and so that we could move efficiently from the group shots to the headshots, but I am going to simplify). It's the day of their staff retreat and they will be arriving at 5 from another location, so I have to do the group shot first.
I am thinking of arranging them in three concentric semi-circles, 6 people in the back, 5 in the middle, 4 in the front (I think this is actually a 15 person group shot, not a 16 person shot... but if it's 16, I'll just add one more to the back row. I know I'm doing 13 headhots afterwards).
It may be that flowers and plants on the left of the security desk will balance with the plants on the right, and then I can frame out most of the big wall to the right of the frame.
Thanks again for all the input. I appreciate it very much.
Wish me luck!
