Michael Dean Gibbs Posted December 5, 2006 Share Posted December 5, 2006 I was watching "Casino" last night and came away with a few questions... There have been wonderful discussions in this forum on the lighting techniques of Robert Richardson's, and I, like many of you am a huge fan. In "Casino" he combines xenon lighting and his signature harsh top-light effect in the same shot (eg. wide angle shots inside a dingy bar). Why is it that xenon rays show up on film as a ray of light and his harsh overhead lighting (4-6 stops overexposed) doesn't? Is it simple a matter of strength...wattage? If so, is there a rule of thumb as to what will show up and what won't? Thanks for your help! Link to comment Share on other sites More sharing options...
Jonathan Bowerbank Posted December 5, 2006 Share Posted December 5, 2006 I don't know what shot you're talking about, but I'm assuming the subject is backlit by either a Xenon or HMI, while top light by another source. It's not a characteristic of the light to see the beam unless the set has been smoked, which is probably the case here. But you're right about the lights wattage making a difference. To get a really good shaft of light you really need that light to be bright, at least a few stops over key. Link to comment Share on other sites More sharing options...
Kim Sargenius Posted December 26, 2006 Share Posted December 26, 2006 It's not a characteristic of the light to see the beam unless the set has been smoked, which is probably the case here. Actually, it's a combination of the 'optics' of the source, the atmosphere (smoke) and overexposure. A light source such as a search light, beam projector or a Dedo collimates the light - most of the light follows the path of the 'beam', very little stray light. Most xenon lights are of this type. A light source with less precise optics (think redhead etc) will scatter the light more and so doesn't produce a distinct 'beam'. Of course, to get that hot white beam you also need a certain amount of atmosphere to 'display' the beam and a few stops overexposure, preferrably against a darker background (try creating a beam in a white cyc!) cheers, Kim Link to comment Share on other sites More sharing options...
