marc, nice pics - and an amazing speed! what camera-setup do you use when you work that fast?
I use the hasselblad H3D either with the 35 mm or the 50 -110mm lens.
Before that I worked with a Nikon D2x but the files were too small to cover double page spreads.
So my digital shooting system actually came from the nikon set up, which was a radical change from my pentax67.
I think I also go fast as i do not like my client to be present and look over my schoulder all the time
to check every angle,
You are also absolutely right, shooting with or with out lights really depends on so many factors like client's need, personal style etc
The thing though is that I rarely see any cutting edge designed interiors shot with lights like you do, only the more conservative ones, so I for me I quickly equate that shooting style as conservative. But again it all depends on who pays your bills and what they want.
