When it didn’t say, “Episode IV.” When there was exactly one “computer-generated image” in the entire picture. I also wish for “the first Star Wars movie, exactly as it was.” Exactly as I originally saw it. I frequently wish that DVDs (and downloads) of “older, film” material would include a non-“corrected” version, as well. I don’t think they “fixed” anything by doing that. They used it for dramatic effect which was simply removed when “color correction” became the rage and filmmakers wanted to “fix” their old stuff. But it was a thing that set lighting designers knew about, that film directors knew about, and that makeup, costume and prop designers knew about. This is no longer true of digital, nor of CG rendering unless you cause it to be. They understood and used “how film works.” You can use that principle to dramatic effect, adding a certain palpable intensity to the scene. The film medium had at least three layered color emulsions, and they did not all perform the same way when exposed to colored light. You also observe that the non-linear profile is not the same at different areas of the color spectrum. If you look at several of the film-profiles shown above, you immediately see that the sweep from dark to light is certainly not “linear” at all. HDRI and the like begin to come vaguely close to this now. (The human eye has “more than twenty-two f-stops of perception,” since it actually scans the scene to construct “what you ‘see’” within your brain’s amazing visual cortex. And, it still has applications to video and to digital photography to this day, even though “ordinary” digital cameras now support features like HDRI, which can capture an image much more closely to how the human eye perceives it. It was a simplification of how film responded, but an imminently practical one. Another thing that you should study was photographer Ansel Adams’ famous “Zone system.” He broadly described exposure in ten “zones,” from opaque-black to blown-out white, with “Zone 5” in the middle.
