Talk:Sodium vapor process

Notes on origin, technical details
In this long article on Ub Iwerks' life and work, search down to "prism" toward the bottom. http://www.geocities.com/side2prod/IwerksFilmFax.htm Jeffreykopp 08:26, 18 December 2006 (UTC)

Sodium Vapor process could not have possibly been used for the Disney film "Song of the South",as Kodak positive-negative color motion picture film stock was not commercially available prior to 1952. —Preceding unsigned comment added by 98.110.66.154 (talk) 12:59, 13 May 2009 (UTC)

Are we sure that it is not Petro Vlahos who invented this process?

Looking at this patent (US3095304A) it seems that this is the process we are talking about while the one from the introduction is about something different. There seem to have been predecessors, I haven't checked them out but Vlahos claims in his patent that it is his novel approach to use Sodium vapour light. We could use the images from the patent, I imagine? I have done little research on this topic. Of course it might be that the patent might be credited not to the person who "actually" invented it.
