Well, I didn't do a lot of studio sessions, but still do have my good ole Arri fresnel main light. Those are great, but like all "hot lights", actually hot! I was told Hurrell used those too, and wisely did so, in a deliberate attempt to mimic movie lighting of the times. Really the best of both in my opinion, during that era. Now in many cases, great camera and lighting work simply gets replaced with loosey goosey digital substitution. Hurrell's work had real glamor, today's movies, mostly teenage influenza germs, corn syrup drinks, and popcorn all over theater seats after some ultra-noisy blockbuster movie where 70% of the actors are cyber figments anyway.
