28 Critical Reflections: random 1 t0 7

Even admitting that what happens in a camera obscura is something 'similar' to the phenomenon of the specular reflection (which is not questionable), what changes is the fact that an image remains traced somewhere, and any successive discussion about its iconic properties deals with the imprinted image and not with the process itself.[3]

There is an inside and an outside to every form. When they are in special accord, as for instance a nut in its shell or a child in the womb, or in the structure of shells or crystals, or when one senses the architecture of bones in the human figure, then I am most drawn to the effect of light. Every shadow cast by the sun from an ever-varying angle reveals the harmony of the inside to outside.[7]

The term specular means that light is perfectly reflected in a mirror-like way from the light source to the viewer. Specular reflection is visible only where the surface normal is oriented precisely halfway between the direction of incoming light and the direction of the viewer; this is called the half-angle direction because it bisects (divides into halves) the angle between the incoming light and the viewer. Thus, a specularly reflecting surface would show a specular highlight as the perfectly sharp reflected image of a light source. However, many shiny objects show blurred specular highlights.[6]

And I know this sounds odd, but most of the flying people were carrying briefcases. Maybe it was their lunch, or maybe... I don't know, it could have been they needed paper, for some purpose I didn't understand.[2]

Terrific contrast between the strong, tactile sculptures and the exuberance of the foliage and flowers. Apart from one or two pieces marked Do not Touch, you can touch and stroke the sculptures in the garden: take advantage, it's quite an experience.[8]

And the play of inside against/with outside, the seeing through, the laid bare view, makes everything that is around part of the sculpture too.[4]

Even admitting that what happens in a camera obscura is something 'similar' to the phenomenon of the specular reflection (which is not questionable), what changes is the fact that an image remains traced somewhere, and any successive discussion about its iconic properties deals with the imprinted image and not with the process itself.[3]
