Agriculture of Kerala




Agriculture of Kerala

Coconuts in Kerala are used extensively in the delicious cuisine of this state. The juice of the tender coconut is drunk fresh, the soft flesh of the tender coconut is eaten raw, and the mature flesh is grated and added to curries or added as garnishing in either fresh or fried form. Coconut oil is extracted from the dry flesh of the coconut and is used for cooking. The distinctive taste of coconut oil adds a special touch to the cuisine of Kerala. The dried and desiccated flesh of the coconut, called copra, is stored for use in cookery and as offerings in temples. A favorite drink made in Kerala is toddy or fermented palm wine, which is extracted from the coconut palm. Coconuts in Kerala are essential for the preparation of favorite dishes such as coconut chutney, avial (mixed vegetable curry) and fish moilee. A true Malayalee cannot imagine what life would be like without coconuts in Kerala. You can taste the delicious cuisine of Kerala, of which coconut is an essential element, on tours of Kerala, with Kerala Backwater.

Coconut Trees in Kerala
The coconut tree (Cocosnucifera) is a very important part of the landscape, traditional lifestyle and economy of Kerala, as you will see when you travel to Kerala with Kerala Backwater.
Every part of the coconut tree is used in some way. The many uses of the fruit have been described above. The trunk of the coconut tree is used for its wood to make beams in traditional houses and the coconut palm's leaves are used to thatch houses and weave mats, baskets and other useful household items. The husk of the coconut is used to produce coir, which is woven into ropes, doormats and furnishing material. The curved shell of the coconut is used to make spoons and ladles. Every part of the coconut tree is put to some use. Coconuts in Kerala, are more than just a beautiful part of the landscape or an essential element in Kerala cuisine.

Coconut trees are essential to the traditional lifestyle and livelihood of the people of Kerala, as you will see when you travel on Kerala tours with Kerala Backwater.

Rubber tapping in Kerala

The rubber plant is not a native plant of India. Dutch colonialists who also cultivated rubber in their plantations in Indonesia introduced the rubber plant to Kerala, India, because of its similar tropical climate. The Rubber plant (its botanical name is Haveabrasiliensis) produces sticky, white latex that is collected and processed to produce natural rubber. A rubber plant has to grow for about seven years before it can be tapped on a regular basis. A rubber tree can be productive for over 20 years. Rubber trees are characterized by their straight trunks and smooth green leaves. The rubber is harvested by rubber tappers who make a long curving cut on the outer bark of the trunk of the rubber tree. The latex from within the tree seeps to the surface of the cut and trickles down the cut into a container, tied to the tree by the rubber tapper. Every morning the rubber tapper empties the cup tied to each tree, in the area of the plantation that he works in. After a few days he will make another cut just above or below the first cut, thus extracting more latex from the rubber tree. Eventually after about 20 years the rubber tree will stop producing latex, upon which a new tree is planted in its place.

Apart from rubber trees other plants grown alongside include spices, areca nut and cashew. You can see the local farmers and plantation workers tending and harvesting the crops on rubber plantations in Kerala, while on nature tours in Kerala.

Tea Plantations in Kerala

On Kerala tours, as you travel to the hill ranges of the Western Ghats in Kerala, you'll find some of the highest tea estates in India in and around Munnar. Tea plantations and tea cultivation were introduced to Kerala by British settlers in colonial times, when they found that the temperature and soil conditions of the hill ranges of Kerala were suited to tea cultivation. India is today the world's largest tea producer and exporter.

Tea cultivation in Kerala
The tea plant (Camellia sinensis) was introduced to India by the British during colonial times. The bush has shiny green leaves with pointed ends and have a pleasant aroma. Take a deep breath as you walk through a tea plantation in Kerala and you can feel the fragrance of tea invigorate you. Tea bushes will grow to tree height in the wild. On plantations however tea bushes are maintained at waist height so the leaves can be plucked easily. Tea picking is carried out by hand, usually by groups of women. Their agile fingers pick only the bud and first two leaves of each shoot and place them in a basket slung behind their backs. The women often sing as they work to help them sustain a rhythm as they move along the rows of tea bushes. The tea leaves are processed after plucking and sorted into categories based on fermentations and other processing treatments. The three broad classifications of tea are - Green Tea, Oolong Tea and Black Tea.


Apart from tea bushes other plants grown on tea plantations include pepper, cardamom, cashew, and areca nut. The shade trees grown to shelter tea bushes are also harvested for their fruit. You can see the see the process of tea picking and processing on tea plantations in Kerala, while on nature tours in Kerala.

Spice Plantations

Kerala is known for its fabulous spices. Traders from ancient Phoenicia made tours to Kerala to carry back its aromatic spices to Mediterranean lands. Pepper, cardamom, cinnamon, ginger, cloves and more… the spices of Kerala were used in the West to all flavors to food and wine and to preserve meat during the cold European winter.

Spices can be defined as "aromatic substances of vegetable origin, used for flavoring food or as a preservative." Many spices are also known to have medicinal value, for instance turmeric is a known anti-oxidant and curry leaf can control prevent diabetes.

The East India Companies of various European powers - the Portuguese, the Dutch, the French and the English fought over possession of the trade routes and the precious spice plantations of Kerala. Today you can simply take a tour with Kerala Backwater and find yourself enjoying the hospitality of the spice plantations of Kerala on Kerala tours.

The spice plantations of Kerala are fascinating farms to wander in, for different sections of each plantation are dedicated to different spices. Apart from spices traditionally grown in India such as pepper, cinnamon, ginger and cardamom farmers in Kerala have taken to growing spices that are used worldwide. Some of the spices cultivated in spice plantations are vanilla, oregano, rosemary, thyme, basil, mint, bay leaf and sage.

Take a trip to the spice plantations of Kerala and feel transported into a green paradise. Walk through the aromatic spice gardens where the air is laden with the fragrance of nature's bounty. Some spice plantations in Kerala offer tourists accommodation in the lodges and mansions on the plantation. Guest can stay with the plantations owner's family and enjoy home cooked traditional Kerala cuisine and witness the activities of the spice plantation. Go for nature walks and bird watching treks, wander through the plantations, taste the various spices and breathe in the fragrant air on Kerala tours of the spice plantations of Kerala with Kerala Backwater. The tranquil spice plantations of Kerala are a refreshingly different eco tourism option among Kerala tours.

BACKGROUND LIGHTING [Film Technology]




BACKGROUND LIGHTING 
[Film Technology]

To illuminate set, to create atmosphere. Light illuminating the background alone. Large scenic backgrounds such as cyclorama and back cloths (back drops) can be lit in various ways, depending on the effect want to achieve. Fresnel spots can provide areas of light of reasonably controllable shape, generalized blobs, or streaks and simple shadow pattern or light patterns. Flood lights can wash an area of background with soft light(white soft light or coloured[colour soft light]). Ellipsoidal spots can produce fairly localized precise light pattern formation. A more controlled method of lighting background is needed and several special units (CYC lights) have evolved for the purpose. The simplest is the strip light (border light). In a more sophisticate design, tubular line filaments are offset with in their curved sheet reflector so that the light emerges in an elongated lob. The light from a series of units, blends with that from a row on the ground. Where a shaded CYC is required, a row of ground troughs alone is used. Colour filters can be fitted over them, either to obtain a continuous single-colour effect or by different colours in alternate lamps (e.g. blue filter, amber filter) these can be controlled to produce colour mixtures[mixed colour light]. The most advanced cyclorama lighting units have specially shaped reflectors that enable to light a background evenly with hung light units alone critically positioned, they produce flat over all illumination when located 10 ft (3m) from a cyclorama at 8 ft (2.5m) intervals. Typical bulbs are 625/1000/1250W per individual fitting. In single twin, or four light forms, they can be used with white, red, green or blue units to provide colour light mixing.







AUXILIARY FILL LIGHT [Film Technology]




AUXILIARY FILL LIGHT

Principle - Iron coiled coil across the power supply. Variable voltage can be tapped off to feed lamp.
Advantages - Cool working compact, reliable, smooth control with varying load. Excellent power economy.
Disadvantages - Suitable only for AC . relatively expensive. Bulky.








AUTOMATIC VOLTAGE CONTROL [Film Technology]




AUTOMATIC VOLTAGE CONTROL
[Film Technology]

[In generator] Automatic voltage regulation(AVR) ensures that variations in the power drawn from a supply do not cause changes in the supply voltage. Without such control, increasing power loads can cause the line voltage to fall; or to rise rapidly (surge) when an appreciable load is removed- possibly burning out(blowing) remaining lamps. Unregulated power sources are load conscious, their voltage dropping as power consumption increases (this results in progressively lower light out-put from each lamp, and falling colour temperature). Great care is needed when load shedding (switching off) as voltage can suddenly rise and burn out any lamps remaining lit (mechanical governors on generators or automatic voltage control can alleviate this problem).






AUTOMATIC SCAN TRACKING [Film Technology]



AUTOMATIC SCAN TRACKING
[Film Technology]

In omega wrap: helical scan machines, to produce a sufficiently high head to tape speed and to record one held per head scan the tracks have to be long and oblique. It is difficult to follow such tracks accurately on replay, especially when using a machine other than the one on which the recording was made. Some machines are provided with a separate replay head which can be moved very slightly at right angles to the track by feeding a voltage to it; this is in addition to the main movement along the track. By sensing the signal level off the tape a voltage is fed to the head  so that the signal level off the tape is maximum. This facility is called automatic scan tracking. This particular format has been agreed as a standard for recording on 1 tape and is known as the tape A format. This format standard is internationally agreed by EBU & SMPTE.







AUTOMATIC PATCH PANEL [Film Technology]


AUTOMATIC PATCH PANEL 
[Film Technology]

The flexibility of a typical patch board is at the price of cumbersome `knitting’ as patch cord intertwine. To avoid this, various automatic patch panels have been devised, but probably the neatest is the small cross matrix panel with selector pins, in which outlets(vertical) and channels(horizontal) are marked on a punched board and can be re-patched in a moment.









AUTOMATIC EXPOSURE METER [Film Technology]





AUTOMATIC EXPOSURE METER 
[Film Technology]



Most amateur cameras have a built in exposure meter which automatically adjusts the aperture and controls the amount of light reaching the film. It is simple to use, the operator merely sets the exposure rating on the camera at the subject. The amount of light reflected [reflection] from the scene actuates the light cell, which in turn opens or close the lens aperture. The process is virtually instantaneous and continuous. So that while the film is being exposed, if the camera pans to a darker area or the sun suddenly appears, an automatic adjustment is made.








AUDIO MIXER [Film Technology]

ASTRONOMICAL PHOTOGRAPHY [Film Technology]



astronomical photography 
[Film Technology]

     In no other field of science has photography played a more important role than in astronomy. By placing the photographic plate in the focal plane of a telescope, astronomers can obtain precise records of the locations and brightness of celestial bodies. By comparing photographs of the same region of the sky taken at different times, proper motions of certain objects such as comets can be detected. An important quality of the photographic plate for astronomy is its ability to record, by means of long time-exposures, astronomical objects too faint to be observed with the naked eye.  Recently, the sensitivity of photographic recording has been improved by image-enhancing techniques. In a process known as the photoelectric effect starlight liberates electrons on a photocathode that is placed in the focal plane of the telescope. The liberated electrons are directed to a photographic plate to form the image. Computer enhancement techniques create sharper, more detailed images from sometimes fuzzy and distant photographs from outer space. Computers digitize the photographic information and then reproduce it with greatly improved resolution. In a further refinement, charge-coupled devices (CCDs) dispense with a photographic plate altogether; individual photons are recorded electronically, and are distributed by a microprocessor along a series of picture elements (pixels) which when built up in rows, form an image which can be manipulated digitally by computer. The pixel in these pictures is thus analogous to the silver-halide grain in conventional photography in governing the resolution of the image. CCDs are the imaging technology used by the Hubble Space Telescope and space exploration probes such as Galileo, and are the prime system used by the world's major terrestrial telescopes, such as the Keck Telescope. The reason for their dominance in this area is their superiority in registering very faint astronomical objects; their ability to record individual photons gives tham a light-collecting power far greater than even the most sensitive film.






ARTIFICIAL LIGHT SOURCES [Film Technology]



artificial light sources
[Film Technology]

     In the absence of adequate sunlight, photographers use artificial light to illuminate scenes, both indoors and outdoors. The most commonly used sources of artificial illumination are the electronic flash, or “strobe”; tungsten lamps called photofloods; and quartz lamps. Another once-popular light source, the flashbulb, a disposable bulb filled with oxygen and a mass of fine magnesium alloy wire that fired only once, is largely obsolete, having been replaced by inexpensive, economical electronic flash units. The electronic flash (effectively a kind of stroboscope) consists of a glass quartz tube filled with an inert gas and a halogen gas at extremely low pressure. When high voltage is applied to the electrodes sealed at the ends of the tube, the gas ionizes and produces an intense burst of light of very short duration, a flash. Although large, special-purpose units can produce a flash of about 1/100,000 of a second, most produce flashes lasting from 1/5,000 to 1/1,000 of a second. Flash units must be synchronized with the shutter of the camera so that the burst of light covers the entire scene. Synchronization is achieved through an electrical connection between camera and flash unit, either a bracket mounted on top of the camera, called a “hot shoe”, or a cord called a “synch cord” that runs from the camera's synchronization socket to the flash. Automatic flash units are equipped with sensors, photocells that automatically adjust the duration of the flash for a particular scene. The sensor, which measures the intensity of the flash as it occurs, cuts off the light when adequate illumination is obtained. The dedicated flash, a newer type of automatic flash, is designed to function as a unit with a particular camera. The electronic circuitry of the flash and camera are integrated. The sensor is located inside the camera and gauges the amount of light at the film plane, allowing more accurate measurement of flash intensity. Flash units vary in size from small camera-mounted units to large studio flash units. Generally speaking, the larger the unit, the greater the intensity of light produced. Camera-mounted flashes are adequate for illuminating small scenes, but to illuminate a large scene evenly, and with a single burst of light, a powerful studio unit is needed. Photofloods, incandescent bulbs with filaments thinner than those used in ordinary light bulbs, provide continuous light. For normal colour rendition in colour photography, photofloods must be used with either tungsten-balanced film or a light-balancing filter. Quartz lighting, the standard of the television industry because of the great intensity of light produced and relative longevity of the bulbs when compared to tungsten sources, is also popular among still photographers.
