I'd say that paper presents alot of interesting and practical information for those attempting to design a system for dimwit camera operators. However, it seems to me to be irrelevant if one determines one's own EI, especially if one is shooting only negative film.

Having said that I am a fan of the contemporary Nikon matrix system which addresses many of the same issues in a suitable, practical manner: http://www.mir.com.my/rb/photography...xflowchart.htm

I'm no Nikon fan, but their matrix metering system seems to be designed by some knowledgable folks to address many of the significant exposure issues illustrated by Steve's posts on exposure and film sensitivity.
