I read in a recent article on moviefone that there is a common technique of shooting scenes inverted (left is right and vice versa).
Apparently this was used in Star Wars to shoot a scene including Darth Vader, which causes his breast plate to be reversed.
Unfortunately I read the article on my phone and I seem to be incapable of finding it again. (If I do, I will link it here.) It didn't say anything about the purpose of this technique though.
- Is there really such a "trick" that is commonly used to shoot scenes with everything the wrong way around and then mirror the image horizontally?
- If there is, what is the purpose of this technique? I really can't think of any advantage, only of problems. (In contrast to say, shooting scenes backwards for special effects.)
I finally found the link again!: Sci Fi Movie Mistakes
Star Wars (1977)
We guess Darth Vader's uniform is always messed up. When Vader (David Prowse) and Obi-Wan Kenobi (Alec Guinness) are fighting in the original 1977 "Star Wars," Vader's chest plate and belt buckle are on backwards. However, that was due to the entire shot being reversed -- a technique often used in movies -- as the light grates and walls in the background are also switched around.
Maybe the exact quote will help identifying this alleged technique and it's purpose.
