What a wonderful, eloquent video on light and lighting from Disney Imagineer Joe Rohde.

“…the human body’s response to light is more ancient than the human body itself…”

Which is dead to nuts accurate: The wavelengths of blue light that penetrate the ocean the deepest match nearly exactly human melanopic response.

“…always remember, in a built environment, when you’re looking at a light, you are not only looking at a function, but you are looking at a little, encapsulated emotion…”

So true. Every light source will trigger – for better or for worse – an emotional response in us humans. So let’s get it right!
