It’s a very popular observation spot and permits try to manage its overuse. Errant car headlights can spoil an observation, the area caters to enthusiasts that follow a slew of best practices (only using red flashlights in the dark to preserve night vision, etc).

- maxxxxx 9y agoFrom my experience it works. Sometimes I wonder if it works mainly because most red lights are pretty dim.
- bdamm 9y agoReducing blowout by 2/3rds of the spectrum (or more) seems like a good thing. I don't get the "myth" people. Maybe they just prefer blue or green dim lights? Historically it's got some influence from black and white photography, where black and white film was typically least sensitive to the red spectrum and sometimes not sensitive at all, giving a small frequency window where one could operate in a "dark" room without exposing the film the photographer was working with, because the human sensitivity to red is many times better than the film's sensitivity to red.
- maxxxxx 9y agoWith digital it seems almost the opposite way. When you lightpaint with red even barely perceptible light has a huge effect compared to other colors. Blue for example doesn't register much in comparison.
