Check out the back issues of View Camera for that articl. It was from a few years ago, and has a shot of Bogart on the cover, if I remember correctly. The article went into great detail about Hurrell's style, methods and negatives... This article also talked about the various lenses he used & their individual characteristics--how he "misused" the lenses and took advantage of their flare etc in conjunction with the arc lights the studio let him use. Goes into a short study of his negatives, and then the author details his method for a modern approach using the grids on strobes and an old calumet C400, if I recall.

May not be 100% authentic, but it was a good article nonetheless...plus Camera Arts seems to sponsoring this site, might as well look up one of their publications.
