Apparently it is a type of projection screen, but I have never heard the name. Thanks for any help.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 07-08-2003 07:28 AM                        Sounds like French to me.  |  IP: Logged Dick Vaughan Phenomenal Film Handler Posts: 1032 From: Bradford, West Yorkshire, UK Registered: Jul 2000 posted 07-08-2003 07:49 AM                        A quick google search for "Cordon Ecran" comes up with screened cord(or cable) but no cinematic references.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 07-08-2003 08:13 AM                        quote: Sounds like French to me. Oui! As a masculine noun has it two meanings; cord, as in a synonym for string or rope (e.g. cordon d'alimentation - power lead, or cordon médullaire - spinal cord) and cordon as in barrier (e.g. cordon sanitaire - quarrantine). If you were trying to describe a screen made of cord (i.e. 'cordon' being the adjective, not the noun) I would expect it to be 'écran de cordon' (like écran de fumée - smokescreen), not 'cordon écran'. 'Cordon de écran' would be 'cord of screen', whilst omitting the 'de' turns 'écran' into a verb, i.e. the 'screened cord [cable]' uneartherd by Dick's Google search. There again I haven't formally studied French for 16 years and my only recent experience of using the language is on holiday and after having drunk significant amounts of the substance which I understand the US now refuses to import on patriotic grounds, so the above might not be quite right!  |  IP: Logged Dick Vaughan Phenomenal Film Handler Posts: 1032 From: Bradford, West Yorkshire, UK Registered: Jul 2000 posted 07-08-2003 09:41 AM                        quote: 'screened cord [cable]' uneartherd by Dick's Google search.

So perhaps it is a Cinerama type screen,just like ours in Bradford Why didn't I think of that  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 07-09-2003 12:14 PM                     Dick sair "Quite possibly.

You then measure from the center of the screen to the line. This measurement is the cord. When you measure the projection throw distance you measure to the cord not the screen surface. Remember to measure from the aperture plane not the port.  |  IP: Logged Mark Lensenmayer Phenomenal Film Handler Posts: 1605 From: Upper Arlington, OH Registered: Sep 1999 posted 07-09-2003 01:13 PM                     From THE WIDESCREEN MUSEUM of Marty Hart: Screen Chord  |  IP: Logged Bob Maar (Maar stands for Maartini) Posts: 28608 From: New York City & Newport, RI Registered: Feb 2001 posted 07-09-2003 01:23 PM                        In Mark's terrific post, they are measuring from the picture edge which is the correct way to proceed.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 07-09-2003 03:24 PM                        quote: Leo was the pun intentional Nope, just a typo - sorry to disappoint!  |  IP: Logged Hugh McCullough Expert Film Handler Posts: 147 From: Old Coulsdon, Surrey, UK Registered: Jan 2003 posted 07-09-2003 03:57 PM                        Thank you everyone for your replies. A theatrical friend tells me that he thinks an Ecran Cordon was used in the live theatre.(Probably Victorian) It seems to have consisted of a central panel with a number of reflective panels, angled towards the centre, on either side. A picture, probably from a Magic Lantern, was projected onto the centre, and reflected by the side panels thereby giving a type of 3D effect. So this could be an early form of what we now call a lenticular screen. The name still survives in the world of French made wide angle of vision plasma screens.Or so Google tells me. I rather like Gordon's explanation.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 07-10-2003 02:18 AM                        This book (which a friend of mine translated) is pretty much the definitive history of Victorian optical media technology. A colleague has my copy, but I'll try and repossess it from her and see what it says about écrans cordon.  |  IP: Logged
