I have this weird idea. I wanna capture a beam of light. Like the huge soft light coming in from a window and not only being able to catch the light falling on subjects inside, but the actual beam of light as it comes in. You often see these kinds of lighting in cinematography, is it possible to do with still photography? I have tried to catch head lights from cars, really hard, only possible to do in fog for me. How would you go about? I had this weird idea about adding some kind of dust or maybe smoke from a smoke machine to be able to do this, but I want it to be a bit even.
