Iridescence (also known as goniochromism) is generally known as the property of certain surfaces which appear to change color as the angle of view or the angle of illumination changes. Iridescence is commonly seen in items such as soap bubbles, butterfly wings, and sea shells.

Etymology

The word iridescence is derived in part from the Greek word ἶρις îris (gen. ἴριδος íridos), meaning rainbow, which in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and acted as a messenger of the gods. Goniochromism is derived from the Greek words gonia, which means angle, and chroma, which means color.

Photography

Conventional photography only records the specific effect of iridescence (not the phenomenon itself), just as it only captures the effect of three dimensions (representing them with two); however, iridescence can be reproduced by holography (which includes phase information).

I searched this out of curiosity and because of the late single of the Band Linkin Park, "Iridescent". And I found that this word means a lot of thing to me, as an Photo/Image enthusiasts, and as a human.


Iridescent is also the soundtrack of coming "Transformers 3: Dark of The Moon"
from their fourth studio album A Thousand Suns





When you were standing in the wake of devastation
when you were waiting on the edge of the unknown
with the cataclysm raining down, insides crying save me now
you were there and possibly alone.

Do you feel cold and lost in desperation
you build up all the failiures all you've known
remember all the sadness and frustration
and let it go, let it go.

And in the burst of light that blinded every angel
as if the sky had blown the heavens into stars
you felt the gravity of temper grace falling into empty space
no one there to catch you in there arms


Do you feel cold and lost in desperation
you build up all the failiures all you've known
remember all the sadness and frustration
and let it go, let it go.

(Multiple Voices)
Do you feel cold and lost in desperation
you build up all the failiures all you've known
remember all the sadness and frustration
and let it go,

let it go
let it go
let it go
let it go

Do you feel cold and lost in desperation
you build up all the failiures all you've known
remember all the sadness and frustration
and let it go, let it go.




This song for me is very meaningful. This song became one of my favorite. It deserves to be listen, feel and understand. This song makes Linkin Park my favorite band again as of 2011.
