That -3 for motion picture cameras strikes me as weird. As far as I can tell motion picture cameras are way different from still cameras, the lenses focus differently (as I understand it there's a second man on whose job is to handle the focus of the lens, the focus puller) and use t-stops rather than f-stops.

There is a photography book on the wishlist, I'd love to see that written. I don't think I have enough knowhow to write it myself.

Oh, and yes, Photography is a hobby of mine.
