One other thing
that should be understood is that even the brightest bioluminescent
organism is pretty dim compared with the sun or a 25 watt bulb. Fireflies
look bright against a dark summer sky. But in the daylight you can't even
tell if they're glowing. The same applies to those cool deep-sea fish
and, I suspect, luminous plants. Luminous plants would lose some crowd
appeal if you had to view them in pitch black and wait for your eyes to
accustom themselves before you could even see their faint glow. Tell me
if I'm wrong about this.
ted, there is no right or wrong about this. in darkrooms for photography,
folks navigate by means of very dim photoluminescent dabs of paper
tape. these could be come obsolete!
it is a matter of subtlety. if you have ever seen a pitch black stage,
come to life very slowly as the stage lights just BARELY come on, you
would know what I mean. also folks vary in their ability to see in the
dim light. I grew up reading under blankets by penlight. I wear
sunglasses like welders goggles even indoors in Southern California. very
light sensitive eyes.
