Mitch Gross Posted January 16, 2004 Share Posted January 16, 2004 Because they are being precise. Kodak currently has a single 250 ISO (ASA is outdated) filmstock, but it replaced another from the past. And Fuji has two 250 ISO stocks, one tungsten and one daylight balanced. By giving the stock number it is the most accurate way to convey information. Between the two major manufacturers there are seven 500 ISO film stocks.

stijnbarbe Posted January 18, 2004 Share Posted January 18, 2004 yes, DP's use the numbers like 7218 and 7279 to indicate a specific product. in this case the kodak number indicates 16mm (=72 and 52 for 35mm) and two different 500ISO tungsten stocks. 18 is vison2 where 79 is the 'old' vision stock. Fuji does the same thing: 86 for 16mm and 85 for 35mm. Link to comment Share on other sites More sharing options...
Premium Member John Pytlak RIP Posted January 22, 2004 Premium Member Share Posted January 22, 2004 Here are all the Kodak camera films: http://www.kodak.com/US/en/motion/products...1.4.4&lc=en As others have noted, there can be several films in a given speed class, to give cinematographers a choice of "looks".
