Well, from technology used to color film from the past, here's an idea of how NASA is using tech to get extremely high definition views of the international space station.
Like I would have two Pentax K1000s or two Cannon AE1s, whichever one, I would put black and white film in one, color film in another, so I can compare the shots.
Over in Hollywood, coloured film stock was used to convey the setting, Intolerance is comprised of four different stories, so naturally, each narrative is given its own tint.
