One of the group photos included app. 20 staff in a small hallway. It was impossible to position my studio light, so I used two SB-910s and placed one in the window sill to the left and one on a small ledger to the left of the stairs from the main door. Both Speedlight heads was positioned straight up into the ceiling, but still shadows where cast on the white wall behind the group of people. It required some work in CS6 to reduce those shadows.
Here is the original photo that was used on the front of the invitation for the reception.
Last - but not least - I shot 5 portraits for the web site. Here is one example of partner Peter Mollerup.
I used a Nikon D800 with AF-S 24-70mm f/2.8 and AF-S 70-200mm f/2.8 (for the portraits) lenses. Elinchrom studie light was used for the portraits.
