Setting up for this type of shoot is relatively easy; f8, point and click is the general rule but there are some things to bear in mind for the lighting. We use 4 lights for portraits in the studio - 2 illuminate the back-wall nicely and 2 are used for the subjects. Not all lights are used at once though, for some shots the back lights are switched off - for example, when we want a black or an off-white background. The subject lights may both be used where there is a large group or only one used where there is just a couple or a single subject.
Anyway, to show the difference - here are some examples.
Shot at f11, black background unlit, 2 softboxes left and right of the group
Same front lighting, white background lit with 2 softboxes left and right
Same shot, single softbox left and high of subjects, white background unlit - second shot shows treatment to black and white with vignetting.
