Technology of photography , equipment, techniques, and processes used in the production of photographs. The most widely used photographic process is the black-and-white negative—positive system Figure 1. In the camera the lens projects an image of the scene being photographed onto a film coated with light-sensitive silver salts, such as silver bromide. A shutter built into the lens admits light reflected from the scene for a given time to produce an invisible but developable image in the sensitized layer, thus exposing the film.
During development in a darkroom the silver salt crystals that have been struck by the light are converted into metallic silver, forming a visible deposit or density.
The more light that reaches a given area of the film, the more silver salt is rendered developable and the denser the silver deposit that is formed there. An image of various brightness levels thus yields a picture in which these brightnesses are tonally reversed—a negative.
Bright subject details record as dark or dense areas in the developed film; dark parts of the subject record as areas of low density; i. After development the film is treated with a fixing bath that dissolves away all undeveloped silver salt and so prevents subsequent darkening of such unexposed areas. Finally, a wash removes all soluble salts from the film emulsion, leaving a permanent negative silver image within the gelatin layer.
A positive picture is obtained by repeating this process. The usual procedure is enlargement : the negative is projected onto a sensitive paper carrying a silver halide emulsion similar to that used for the film.
Exposure by the enlarger light source again yields a latent image of the negative. After a development and processing sequence the paper then bears a positive silver image. In contact printing the negative film and the paper are placed face to face in intimate contact and exposed by diffused light shining through the negative. The dense black portions of the negative image result in little exposure of the paper and, so, yield light image areas; thin portions of the negative let through more light and yield dark areas in the print, thus re-creating the light values of the original scene.
In its simplest form, the camera is a light-tight container carrying a lens, a shutter, a diaphragm, a device for holding and changing the film in the correct image plane, and a viewfinder to allow the camera to be aimed at the desired scene.
The lens projects an inverted image of the scene in front of the camera onto the film in the image plane. The image is sharp only if the film is located at a specific distance behind the lens.
This distance depends on the focal length of the lens see below Characteristics and parameters of lenses and the distance of the object in front of the lens. To photograph near and far subjects, all but the simplest cameras have a focusing adjustment that alters the distance between the lens and the film plane to make objects at the selected distance produce a sharp image on the film.
In some cameras focusing adjustment is achieved by moving only the front element or internal elements of the lens, in effect modifying the focal length. The shutter consists of a set of metallic leaves mounted in or behind the lens or a system of blinds positioned in front of the film.
It can be made to open for a predetermined time to expose the film to the image formed by the lens. The time of this exposure is one of the two factors controlling the amount of light reaching the film. The other factor is the lens diaphragm, or aperture, an opening with an adjustable diameter. The combination of the diaphragm opening and exposure time is the photographic exposure. To obtain a film image that faithfully records all the tone gradation of the object, this exposure must be matched to the brightness luminance of the subject and to the sensitivity or speed of the film.
Light meters built into most modern cameras measure the subject luminance and set the shutter or the lens diaphragm to yield a correctly exposed image. The simplest camera type, much used by casual amateurs, has most of the features listed in the previous section—lens, shutter, viewfinder, and film-holding system. The light-tight container traditionally had a box shape. Present-day equivalents are pocket cameras taking easy-load film cartridges or film disks.
Provision for a flash may be built in. Though simple to handle, such cameras are in daylight restricted to pictures of stationary or slow-moving subjects. Technology of photography. Article Media.

Space exploration has created new markets and new technologies that have spurred our economy and changed our lives in many ways. The new features highlight how space pervades our lives, invisible yet critical to so many aspects of our daily activities and well-being. Red light-emitting diodes are growing plants in space and healing humans on Earth. The WARP 10 is intended for the temporary relief of minor muscle and joint pain, arthritis, stiffness, and muscle spasms, and also promotes muscle relaxation and increases local blood circulation.
PCE Instruments' accurate, affordable coating thickness gauge, thickness meter, surface testing and film gauge devices are used for material testing, manufacturing quality control and automotive paint inspection applications. A coating thickness gauge is an essential quality assurance tool when anodizing, galvanizing and applying zinc coating to metallic surfaces. A coating thickness gauge also is used to measure body paint thickness and uniformity on pre-owned cars, revealing repainted spots, identifying hidden damages and exposing undisclosed accidents. This information is important when determining the actual value of a used car.

At first we thought it might have been overkill to equip ourselves with two sprayers, but in the end we were glad we could shoot two colors independently. The TrueCoat doesn't pump paint out of a bucket. It carries the paint with it in a disposable flex liner bag attached to a frame on the bottom of the gun. We found it was the perfect solution.

While noted improvements have taken place in the area of ceramics and metals, it is the field of polymers that has experienced an explosion in progress. Polymers have gone from being cheap substitutes for natural products to providing high-quality options for a wide variety of applications. Further advances and breakthroughs supporting the economy can be expected in the coming years. Polymers are derived from petroleum, and their low cost has its roots in the abundance of the feedstock, in the ingenuity of the chemical engineers who devised the processes of manufacture, and in the economies of scale that have come with increased usage. Less than 5 percent of the petroleum barrel is used for polymers, and thus petroleum is likely to remain as the principal raw material for the indefinite future.
Technical Support:. These coatings are superior to other alternative coatings due to their critical advantage of high adhesion to substrate elastomers, resulting in extended fatigue life of parts prior to cracking. Explore our HPCs. Parts made from a less expensive elastomer, such as EPDM, and coated with HRC show equal or better performance over the same part made from a more expensive elastomer, like silicone.

Manufacturing in space has several potential advantages over Earth-based industry. The space environment is expected to be beneficial for production of a variety of products.
С последней недели Элли переменилась, - произнесла Эпонина. - Она словно погасла и все разговаривает о Роберте. - Казнь потрясла ее, - прокомментировал Макс. - Наверное, женщины от природы более чувствительны к насилию.
Тот, будто сраженный пулей, выронил свою ношу и повернул голову вверх. Заметив махавшую ему Эпонину, Макс, словно чистокровный жеребец, рванулся к цилиндрической лестнице. И уже через две минуты, выскочив на площадку, пылко обнял Эпонину. - Ах, мамзелька моя, - проговорил он, отрывая ее от земли на полметра, - как мне тебя не хватало. Арчи умел проделывать с цветными мячами все, что угодно. Октопаук мог поймать сразу два мяча и отбросить их в разные стороны.
Ему же сейчас по меньшей мере сто лет. - Мы помогли ему - как ты говоришь, своей медицинской магией. - Ах, Симона, _Си-мона_.
