That website you linked to is stupid. Firstly, most of those things he said are "duh" things. Secondly, he was definitely wrong on one point: Rockets most certainly do have windows. Space shuttles (a plane strapped to two rockets and a fuel tank) have even more windows. He claims they have no need for them, which clearly means he knows nothing. Anybody who knows the Apollo 13 story (there's even a really nice film out starring Tom Hanks, Gary Sinise, Ed Harris and a lot of other great actors) knows they
looked out the window and used the Earth as a guide for their reentry burn. Anybody who knows that knows that windows saved their bacon (pun intended, as Kevin Bacon was also in the film.
)
All I know is, I used to attempt to "realistically" light my models for pictures. People bitched and moaned, "it's too dark, wah wah wah." So, I caved and started going for a "Sci-Fi" approach to my lighting and now everybody is a lot happier. So, as I said, people don't want reality.
