I am not a huge Star Trek fan, but I do watch alot of TNG and Voyager. When I catch a TOS episode, and it features Klingons (to be blunt, I only remember one Klingon episode, something about a bar fight on the enterprise… Tribbles?), they are relatively normal looking humanoids, but in the later series they have facial ridges and fangs and stuff.
How was this change explained away in the later series? Or is it only explained unofficially?
The original Star Trek was made in the 60s, with 60s TV technology. By the time the Next Generation came along twenty years later, 1980s TV technology had improved. Thus the facial ridges, etc. were now picked up by the camera.
They were always there, but the old technology didn’t pick them up. It’s much like the change from black and white to color TV: the color was always there, but the technology didn’t allow the color to be broadcast.
You’re confused, TV had been in color the whole time, but the world was black-and-white until some time in the 50’s. Old paintings are in color because artists were mostly insane.
Nitpick: the movie cameras used for Star Trek: The Motion Picture were the first to be able to pick up these details. I understand director Robert Wise crapped his pants when he saw the first dailies.
Actually there weren’t any facial ridges for the camera in the first place in TOS. The Klingons were originally supposed to look like Mongols. Roddenberry had the Klingon makeup changed for ST:TMP to look more like that of the Kreeg, a race of mutants from his failed TV pilot Planet Earth. Twenty years later the Trill got the same treatment. When they were first introduced on a episode of ST:TNG they brow ridges instead of spots. The makeup was changed for ST: DS9.
