thanks sidd
generally it was pretty much like this:
the ones in the cyclorama with emily marilyn and the bed were using a big gridded beauty dish as the main light
and the ones that are much brighter all round, and a bit more "high key" sort of, are the gridded beauty dish as main, and a softbox on the left as fill
the ones in the little room with the checkered floor had a diffused beauty dish, camera right as main
and a softbox, camera left as fill
but as i moved around for some shots, the 'camera left'/'camera right' thing gets a bit muddled around
