The fundamental technology of most photography, whether digital or analog, is the camera obscura effect and its ability to transform of a three dimensional scene into a two dimensional image. At its most basic, a camera obscura consists of a darkened box, with a very small hole in one side, which projects an image from the outside world onto ...
In photography, backscatter (also called near-camera reflection [1]) is an optical phenomenon resulting in typically circular artifacts on an image, due to the camera's flash being reflected from unfocused motes of dust, water droplets, or other particles in the air or water.
Development of particle detection optimised nuclear emulsions in the 1930s and 1940s, first in physics laboratories, then by commercial manufacturers, enabled the discovery and measurement of both the pi-meson and K-meson, in 1947 and 1949, initiating a flood of new particle discoveries in the second half of the 20th century.
Photography – process of making pictures by the action of recording light patterns, reflected or emitted from objects, on a photosensitive medium or an image sensor through a timed exposure. The process is done through mechanical , chemical , or electronic devices known as cameras .
OpenSX70 is a project to replace the printed circuit board (PCB) on the SX-70 with a modern open-source design based on Arduino. As of February 2019, a working prototype is available with some experimental 3D-printed enclosures. The new PCB also features an LED indicator and an audio jack for firing an external flash. [13]
The preposition aboard, for example, can be paraphrased as "on board of". [24] The be- prefix originally meant "about" but, in prepositions, came to mean something closer to "at" or "near". For example, one sense of the preposition before means "at or near the front".
A special type of adverb is the adverbial particle used to form phrasal verbs (such as up in pick up, on in get on, etc.) If such a verb also has an object, then the particle may precede or follow the object, although it will normally follow the object if the object is a pronoun (pick the pen up or pick up the pen, but pick it up).
Particle board, also known as particleboard or chipboard, is an engineered wood product, belonging to the wood-based panels, manufactured from wood chips and a synthetic, mostly formaldehyde based resin or other suitable binder, which is pressed under a hot press, batch- or continuous- type, and produced.
