On-Set Lightsaber Mistakes Made Obi-Wan's Dark Fight Scenes Unfixable
Obi-Wan Kenobi made a change to the way Star Wars lightsaber scenes are made, and it may have rendered the footage unfixable. While many viewers noticed how much brighter the lightsabers were than in other live-action Star Wars projects, the technology used to create that effect may have backfired.
Star Wars movies under George Lucas shot their lightsaber fights with unlit stunt sabers. While the colored light blades were added in post-production, since the prop-sabers didn't naturally produce any light of their own, the lightsaber didn't provide any light onto the actors or surrounding the environment, other than a few circumstances where other on-set lights were used to simulate the effect. The sequel trilogy upgraded the process by creating more colorful lightsaber props with glowing tubes on set, creating a more interactive lighting effect.

The Star Wars shows on Disney+ use a similar process to create the on-set lightsaber effect, although, in the case of Obi-Wan Kenobi, the bright blue of Obi-Wan's lightsaber didn't play nice with the camera technology, damaging the image in a way that might be irreversible.
Human eyes work by using «rods» to receive light and dark signals to aid vision in low light and peripheral vision, and red, green, and blue «cones» interpret the color from light reflecting off objects in the world around us. While full-spectrum light, such as light from the sun, appears white, it's comprised of various wavelengths across the full color spectrum. The vast majority of these wavelengths are invisible to the human eye (like infrared or ultraviolet light), but the wavelengths that are visible to the human eye are picked up by cones,
