Oh, I always take note of the cinematographer's name these days in the opening credits (aka Director of Photography aka Lighting Cameraman) of any movie or tv show I watch. Once your eyes have been opened to, say, the work of Vittorio Storaro, Jack Cardiff, or Gregg Toland, there's no going back.
Remember when the Strobist was helping us all to bankrupt the Rosco folks by asking for those gel sample packs? I remember laughing off my butt when I saw that all the most deeply saturated gels were part of Rosco's "Storaro" series. Of course, I thought. Of course.
OTOH, I probably spend TOO much attention on credits overall, since I used to enter data into the IMDb. It got to the point where I'd lecture people at the drop of a hat on the difference between "&" and "and" in the writing credits... (collaboration vs. rewrite. "and" separates (credited) drafts in order. You see more than one "and" and chances are the movie's gonna be pretty bad). If you don't know a gaffer or best boy from a key grip or dolly grip, btw, the IMDb has
a very handy glossary.
