Dvdmike, you keep ranting on the fact that the grading in the film does not look like their equivalents in real life. Filmmakers always tweak their colors to evoke a certain mood. Yes, even before the days of DI color grading, this was being done. Look at Michael manns manhunter or Cameron films.
Perhaps Raiders is warmer and the foliage is brown and not green but that could have been a creative choice!
