Every instrument that has been designed to be sensitive enough to detect weak light has always ended up discovering that the same thing: light is made of particles.

For when God said, “Let there be light, and there was light,” if we are justified in understanding in this light the creation of the angels, then certainly they were created partakers of the eternal light which is the unchangeable Wisdom of God, by which all things were made, and whom we call the only-begotten Son of God; so that they, being illumined by the Light that created them, might themselves become light and be called “Day,” in participation of that unchangeable Light and Day which is the Word of God, by whom both themselves and all else were made. “The true Light, which lighteth every man that cometh into the world,” — this Light lighteth also every pure angel, that he may be light not in himself, but in God; from whom if an angel turn away, he becomes impure, as are all those who are called unclean spirits, and are no longer light in the Lord, but darkness in themselves, being deprived of the participation of Light eternal. For evil has no positive nature; but the loss of good has received the name “evil.”

 

Augustine of Hippo

 

But I must own that I am much in the Dark about Light. I am not satisfy'd with the doctrine that supposes particles of matter call'd light continually driven off from the Sun's Surface, with a Swiftness so prodigious!

 

Benjamin Franklin

 

The photogram, image formation outside the camera is the real key to photography,it embodies the essence... that allows us to capture light on light sensitive material without the use of any camera.

 

Laszlo Moholy-Nagy

 

At the beginning God said: “Let there be light,” and light was, and light is, and light shall be. So Christianity is rolling on, and it is going to warm all nations, and all nations are to bask in its light. Men may shut the window-blinds so they cannot see it, or they may smoke the pipe of speculation until they are shadowed under their own vaporing; but the Lord God is a sun!

 

Thomas De Witt Talmage

 

Now, since the time of Newton there had been a debate about whether light was a wave---that is, a traveling disturbance in some background medium---or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.
