Light Rays Quotes

Are not rays of light very small bodies emitted from shining substances?

Doth not this Æthereal Medium in passing out of Water, Glass, Crystal, and other compact and dense Bodies into empty Spaces, grow denser and denser by degrees, and by that means refract the Rays of Light not in a point, but by bending them gradually in curve Lines? And doth not the gradual condensation of this Medium extend to some distance from the Bodies, and thereby cause the Inflexions of the Rays of Light, which pass by the edges of dense Bodies, at some distance from the Bodies?

Do not the Rays of Light which fall upon Bodies, and are reflected or refracted, begin to bend before they arrive at the Bodies; and are they not reflected, refracted, and inflected, by one and the same Principle, acting variously in various Circumstances?

For low light, all the light rays participate. We're using all the light coming through a large aperture to make a picture with a large depth of field - totally impossible with a conventional camera.

Do not Bodies act upon Light at a distance, and by their action bend its Rays; and is not this action (caeteris paribus) [all else being equal] strongest at the least distance?

As Attraction is stronger in small Magnets than in great ones in proportion to their Bulk, and Gravity is greater in the Surfaces of small Planets than in those of great ones in proportion to their bulk, and small Bodies are agitated much more by electric attraction than great ones; so the smallness of the Rays of Light may contribute very much to the power of the Agent by which they are refracted.

There's something about light field photography that's just magical.

Unlike regular digital or film cameras, which can only record a scene in two dimensions, light field cameras capture all of the light rays traveling in every direction through a scene. This means that some aspects of a picture can be manipulated after the fact.

For the Rays, to speak properly, have no Colour. In them there is nothing else than a certain power and disposition to stir up a sensation of this Colour or that.

All objects transmit their image to the eye in pyramids and the nearer to the eye these pyramids are intersected the smaller will the image appear of the objects which cause them.

If you think about all the light that enters - that enters the lens of a camera, that's much more than a photo. The light field is all the higher-dimensional information that's lost in a regular photo. When we record all this information, that provides us the opportunity in software after the fact.
