This is one of the high key setups I use quite a bit. I light the background with two medium Chimera strips with no diffusion panels at all (I'm basically using them as big flags). The ket light is a Chimera 5' Octa and the fill is a 24" soft box.
The two background lights are a Profoto ProB2 and meter at ƒ16 at the background and spill ƒ8 at the back of the subject. The key light is ƒ11 and the soft box is ƒ8. The two front lights are a Profoto ProB4.
I use wall boards on the floor to give a little shine to ground the subject. The background is Verywhite seamless.
