OK, so here are two examples of the group shots from last Wed. The first is what you get when I did my best to equalize the background and foreground lighting. Though Thomas in the back left is a bit soft. The other is a composite of a separate background exposure I did before everyone got there while there was still light. It's fine to me, thought in comparison to the first I think it looks less organic and a little too pasted in.

I like the first one better. I think the natural backlighting holds the shot together. In the composited version, you loose the backlight and it looks like it's layered together in photoshop.
I agree, that's what you get when you have to shoot two different things in different light. That said, the second is much sharper and less grainy than the first, so it's a toss-up for their purposes.
Ditto that, Mike. The street lights add a nice backlight on the 1st one for separation.

What is the use of the photo? If the customer wants something to show them "on wall street", I think the second photo says that a lot more than the first. The close up image of stock exchange pillars is more widely known than the wider image of wall street. At first, I thought the first image was just a NYC street. It wasn't till after looking at the second image that I realized the first was on on wall street (and that's coming from a west coaster).
The only detriment to the second image is the gentlemen on the right has his cuff messed up, which my eye is drawn to...
