jvx: I think those shots look great for TMZ; I'd never have guessed, actually. I also love Delta3200 @ 1600, actually, but I've only seen the outcome in XTOL (that's what my lab uses; I've not yet got my hands "wet" at home). Thanks for the detailed response.
Just as a second to VinceC's comment - I've had some luck (more luck than I deserve) with a small piece of paper and a rubber band, arranged so that it serves as a "backstop" to a hot-shoe flash. With the flash set at 60-degree bounce, there's a lot of low-intensity, soft fill. Simple, cheap.
Yeah, yeah - I know: the Pocket-Bounce thingy is exactly this. But I was at the shoot, and rummaging around in the camera bag, and that was all I found. Actually, it was a friend's wedding, and my B&W images came out quite nicely as a result. Still, I like "available darkness" shooting - and if the success we've seen here is any indication, there's a lot to be won in this area.
Cheers,
