Is the 1.66:1 Aspect Ratio actually 1& 2/3 (or, 1.6666666) or do the first 2 digits after the decimal just happen to coincidentally be 6?  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 09-20-2002 03:42 AM                        Unless you use an electron microscope to cut aperture plates, I can't see too many people worrying about the difference...  |  IP: Logged Michael Brown Phenomenal Film Handler Posts: 1522 From: Bradford, England Registered: May 2001 posted 09-20-2002 08:36 AM                     Isn't it around 1.6666666666666666666666666666666666666664:1  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 09-20-2002 08:43 AM                        Standard SMPTE 195 specifies the 1.66:1 aspect ratio as having a projectable image area of 0.825 x 0.497 inches (20.96 x 12.62 mm). The 0.825 is a nominal dimension, the 0.497 is a reference dimension, so tolerances aren't specified. Standards may be purchased from the SMPTE: http://www.smpte.org/smpte_store/standards/ ------------------ John P.
