Alan, AFAIK, the method Kodak is using n ow is the same as what we used as far back as the 60s. The algorithms have improved and thus data gathering and presentation is far superior.

So, on a 35 mm x 12" strip, the 1000 micron down to the 1 micron slid exposures appear as about 1/2" square "boxes" containing all 4 exposures, and there are 11 of these per strip, each box having 1 stop more exposure. They are all plotted as I have shown above in an exposure series, and they are treated mathematically to give a large set of data presentations, some of which are shown on the Kodak web site. Grain is introduced and this is then treated to give the result Kriss describes as "Film Information Capacity".

With color, it is done with R/G/B/N, and of course a set of X-Ray data accompanies all of this so that we can determine turbidity and the proper level of acutance dyes.
