Color light would expose the cyan record on the ortho stock, which also acted as a filter, exposing only red light to the panchromatic film stock.

A Bayer filter on a Charge-coupled device | CCD requires signal processing to get a red, green, and blue value at each pixel.

* H-alpha filter, a specific red visible spectral line created by hydrogen with a wavelength of 6562. 8 &# 160 ; Å

This subsystem consisted of 4 parts, a Cassegrain telescope with a 1. 05 ° by 1. 05 ° field of view, a shutter and red / green filter assembly with 0. 08s and 0. 20s exposure times, a slow scan vidicon tube which translated the optical image into an electrical video signal, and the electronic systems required to convert the analogue signal into a digital bitstream for transmission.

In most digital cameras, the sensor array is covered with a patterned color filter mosaic having red, green, and blue regions in the Bayer filter arrangement, so that each sensor element can record the intensity of a single primary color of light.

In red algae, the action spectrum overlaps with the absorption spectrum of phycobilins for red blue-green light, which allows these algae to grow in deeper waters that filter out the longer wavelengths used by green plants.

In a Bayer filter arrangement, green is given twice as many detectors as red and blue ( ratio 1: 2: 1 ) in order to achieve higher luminance resolution than chrominance resolution.

For the color process, instead of an image four perforations high, the camera exposed eight perforations ( essentially two frames ) consisting of one 4-perf image through a red filter and one 4-perf image through a green filter.

The bluescreen shot was then rephotographed again, this time through a red and green filter so that only the foreground image was cast on film, creating a black silhouette on an unexposed ( clear ) background.

An example is the dichroic prism, used in some camcorders, which uses several coatings to split light into red, green and blue components for recording on separate CCD arrays, however it is now more common to have a Bayer filter to filter individual pixels on a single CCD array.

Single-shot capture systems use either one CCD with a Bayer filter mosaic, or three separate image sensors ( one each for the primary additive colors red, green, and blue ) which are exposed to the same image via a beam splitter.

The Bayer filter pattern is a repeating 2 × 2 mosaic pattern of light filters, with green ones at opposite corners and red and blue in the other two positions.

The marine algal blooms known as " red tides " can result in local filter feeding organisms such as mussels and oysters becoming toxic ; coral fish can be responsible for the poisoning known as ciguatera when they accumulate a toxin called ciguatoxin from reef algae.

In some cases, these colors are filtered out by a red or orange filter coating on the glass.

The image in a daguerreotype is often described as being formed by the amalgam, or alloy, of mercury and silver because mercury vapor from a pool of heated mercury is used to develop the plate ; but using the Becquerel process ( using a red filter and two-and-a-half stops extra exposure ) daguerreotypes can be produced without mercury, and chemical analysis shows that there is no mercury in the final image with the Bequerel process.

Some camera manufacturers modified their products to be used as astrophotography camera such as Canon EOS 60Da based on Canon EOS 60D with a modified infrared filter and a low-noise sensor with heightened hydrogen-alpha sensitivity for improved capture of red hydrogen emission nebulae.

He had the photographer Thomas Sutton photograph a tartan ribbon on black-and-white film three times, first with a red, then green, then blue color filter over the lens.

The three black-and-white images were developed and then projected onto a screen with three different projectors, each equipped with the corresponding red, green, or blue color filter used to take its image.

The absence of carotene in the frogs ' diet meant the red / orange carotenoid colour ' filter ' was not present in their erythrophores.

The function of the blood – testis barrier ( red highlight in diagram above ) may be to prevent an auto-immune reaction.

A red all-terrain vehicle crashed through a barrier outside the Paradise Hotel and blew up when it hit the lobby.

The incident resulted in a lengthy red flag to repair the old-fashioned highway barrier ( a guardrail with wooden supports ) that lined the inside of the track in that area.

According to a study by Florida Solar Energy Center, a white tile or white metal cool roof can outperform traditional black shingle roof with a radiant barrier in the attic, but the black shingle roof with radiant barrier outperformed the red tile cool roof.

Today shooters using modern IPSC raceguns with muzzle brakes and red dot sights are close to breaking the three second barrier, and even shooters using production guns with no muzzle brakes or optical sights routinely break the five second mark.

At higher angular momenta, there is a significant centrifugal barrier ( orange curve ) and an unstable inner radius, highlighted in red.

CM occurs when red blood cells break through the blood brain barrier causing microhemorrhages, ischemia and glial cell growth.

The race had a 65-minute red flag to repair the old-fashioned guardrail highway barrier that Park hit.

He wore tennis shorts and a white sweater with a red V at the neck, the sleeves pushed above the elbows.

For several months now, Jack Carter, a big overgrown boy of fifteen with a fuzzy, pimpled face and greenish catlike eyes with a lot of red in them, had been haunted by a dream, a vision, of a Woman.

Thus Burns's `` My love is like a red, red rose '' and Hopkins' `` The thunder-purple sea-beach, plumed purple of Thunder '' although clearly intelligible in content, hardly present ideas of the sort with which we are here concerned.

At dinner the courses were carried in by tall cuirassiers in red capes and black fur caps topped with tufts of feathers, marching in pairs like guards from a stage tragedy.

The expense ( operating ) budget is to be a program budget, and red tape is cut to allow greater autonomy ( with the Mayor approving ) in fund transfers within a department.

He was a wiry, inscrutable, silent country boy from the red clay of rural Alabama, and he spoke with the broad drawl that others normally make fun of.

No drummers here, no pipers, and the red coats were covered with a fine film of dust.

I would not want to be one of those writers who begin each morning by exclaiming, `` O Gogol, O Chekhov, O Thackeray and Dickens, what would you have made of a bomb shelter ornamented with four plaster-of-Paris ducks, a birdbath, and three composition gnomes with long beards and red mobcaps ''??

There was a glass pane in the front door, and through this he could see into a hallway where a plump woman with red hair was arranging flowers.

His eyes were old and they never saw well, but heated with whisky they'd glare at my noise, growing red and raising up his rage.

I look like an old man, compared '', and he had picked up his photograph with the red Christmas bow still on it.

they were struck out with remarks in red ink, denouncing both the cooks and the management.

Inside, the walls are covered with blue and white tile, the floor with red and cream carpets.

The video signal is amplified and then switched, in synchronism with the three ultraviolet light sources which are sequenced by the rotating mirror so that during one-twentieth of a second only one wavelength, corresponding to red, green, or blue, is seen.

The savage barbarian hordes of red Russian Communism descended on the Athens that was mighty Metronome, sacking and despoiling with their Bolshevistic battle cry of `` Soak the rich '!!
