Ragnar,
There are cheaper alternatives for the slaves. Some of the more modern slave sensors have the option of triggering on the 1st, 2nd, 3rd etc flash.
I seem to remember that there are some studio lights that have this option as well.

The trouble is that this approach ends up with piles of cables, batteries, power packs etc, and for shooting small rooms this may not be practical at all.

Also worth mentioning to shoot RAW for these types of shots. Katrin Eismann has a section in one of her books, IIRC, that shows a single RAW with mixed lighting (and hence colour temperatures) that was multiply processed in the RAW converter, and then hand blended in Photoshop with layer masks. Sounds complicated... but isn't And the results were superb.

Of course, the additional thing you can do (once you're prepared to go the whole way and blend images for white balance correction) is to shoot multiple exposures - you should be able to do this nicely without any flash guns Once again, it's a case of either hand-blending, or running through HDR style applications like Photomatix, Artizen, etc.

I'll see if I can rustle up a link to Katrin's work... (her website is www.photoshopdiva.com )

Well in that case... the Fn control must be an overall adjustment, while the compensation on the slave itself is an adjustment relative to that slave (perhaps )

As I say, when I get a chance I'll give it a whirl with two remote flashes and see what happens

Ragnar,
As far as I am aware, the compensation for slave units is only set on the flash itself. The flash compensation on the camera applies to the pop-up alone (or the flash unit on the hotshoe).

But there are other factors too... Pentax term this "contrast control" flash, IIRC.

TBH, I'll have to try it out. When I use multi-flash it's in a studio-type environment and I have everything on manual Drop me a PM in two or three weeks to remind me if I haven't updated this thread!

@Don: glad it's helped. I'll see what I can do about extra chapters

Sounds interesting, though OT... I'm rather partial to a drop of Laphroaig myself Must seek out some Bowmore to tickle the palette

AF speed has absolutely nothing to do with sensor size Nada.
It's down to expense - big, expensive FF body and they put in a faster CPU, a more sensitive AF sensor, plus perhaps a larger supply. It's also perhaps down to marketing as well. They'll obviously want something 'tangible' for the FF body to make you want to pay the extra money (Because, at the end of the day, APS-C sensors are pretty excellent, and the difference between them is less of an issue compared to years ago)
