Thanks so much for the insights, guys. I was figuring on using available light, as I assumed the architects would already have their lights highlighting what they deemed important (i.e. lighting up other surfaces might ruin what they were trying to express). I can see using some reflected, diffused light to increase the ambient, but not to specifically highlight particular details.
The firm is not interested in purchasing equipment, I am sure. This is more of an opportunity for me than for them. I believe they will be hiring a professional as well - I'm just getting a chance to shoot and see how I do. If I do well, who knows...
Oh, and I don't have an UWA. The widest I've got is the 17-55 2.8. Figured I'd use that on a tripod (with my 30D). Any recommendations on ISO and/or shutter speed? Does the normal 1/(2xfocal length) apply? Or should I be able to get usable photos with extended exposures at low ISO using the tripod and a remote?
