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)Reply


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)Reply

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.

J. Arthur Rank?

According to a comment pinned under the video of Corridor Crew recreating the process, the original prism was produced and licensed to Disney by The Rank Organization and remained their legal property. The comment also claims that it was used as late as Something Wicked This Way Comes. It seems someone has already taken the liberty of incorporating this, anonymously and unsourced, into the article on J. Arthur Rank, which they probably shouldn't have done. Can we get someone to look into this more? Octan (talk) 22:18, 2 October 2024 (UTC)Reply
