My light set-up is all natural light...I'm really blessed with natural light...but I'm sure it would work with studio lights too.
For the background I used a net of small lights...the kind that goes on outside bushes and just hung it on the black felt, which was hanging over my background stand.
***The key to the bokeh is to bring your subject like 3-4 feet in front of the background, get close to them and open up wide with your aperture. ***
I used my 50 1.4 at f1.4
