Possibly shot at ISO400, but underexposed and brought up in post process?
They were shot at ISO400 and brought up in post-processing. There wasn't enough ambient lighting in the background to distinguish some of the darker clothing (i.e. the suits and tuxes) so I had to fill in some of the lighting. All of the pp'ing was done in Lightroom on RAW files.
I wasn't too picky about the noise b/c if I remember reading somewhere on here, it was mentioned that when you print the photos, the noise is not really noticeable. Plus, for the most part, it's not something that really registers with the layperson.
Next time though, I have to work on working more with the ambient lighting and possibly an off-camera flash.
Thanks for commenting guys.
edit: Oh and that last photo of the set... the wall was actually kind of "noisy" so it looks extra noisy there... the wallpaper was some ugly, yellow textured material that made the photo look noisy even before I pp'd it. Yuck.
