Moritz Reinhart Posted September 20, 2018 Share Posted September 20, 2018 (edited) I am preparing to shoot a ballet scene and of course Black Swan is the main reference. I have a question about the following still. There is one source behind her that creates the big visible beam and I think also backlights her. Then there seems to be another source coming from camera right (based on the long neck shadow it creates) and it also seems like a pretty hard source. What kind of source do you think this is and where do you think it is placed exactly ? And why isn't the beam visible (like the one in the background)? Thanks Edited September 20, 2018 by Moritz Reinhart Link to comment Share on other sites More sharing options...

Premium Member David Mullen ASC Posted September 20, 2018 Premium Member Share Posted September 20, 2018 Smoke becomes more visible when the light is coming from a backlit angle, and it is more visible the brighter the light is -- so the 3/4 frontal key would light up the smoke less visibly because it is dimmer and not from a backlit angle.

Brian Doran Posted September 22, 2018 Share Posted September 22, 2018 I found a neat, short explanation of why the angle of light matters in illuminating smoke/vapors. The website seems to be about some sort of rendering software, but this page has a brief explanation of scattering anisotropy. https://help.jawset.com/en/c4d/container_parameters/rendering/smoke_shader/illumination Link to comment Share on other sites More sharing options...
