Fairy Tales for All the World
This year, the world is marking the 200th anniversary of Danish author Hans Christian Andersen with a wide range of events.
Andersen's tales have attracted millions of readers for more than a century. They continue to be among the best-known works of world literature. "The Ugly Duckling (小鸭)" and "The Little Mermaid (美人鱼)" are among the most famous.
He was born on April 2, 1805, in the slums of Odense, Denmark. His father was a shoemaker and his mother worked as a washer-woman. Andersen received very little education, but his fascination with fairy tales inspired him to; compose his own stories and arrange puppet (木偶) shows.
His father died when he was 11. He was forced to go to work, first as an apprentice to a weaver and tailor and then in a tobacco factory. At the age of 14, he moved to Copenhagen to try a career as a singer, dancer and actor. He sang in a boy's choir (合唱团) , but he made very little money. He also tried the ballet, but his awkwardness made this impossible.
Finally, when he was 17, Jonas Collin, a director of the Royal Theatre in Copenhagen discovered Andersen. After hearing Andersen read a play, Collin realized that he had talent. And he got money from the king for Andersen's education.
In 1828, Andersen passed the entrance examinations to the university in Copenhagen. His writings were firs': published in 1829. In 1833, he received grant money for travel, which he used to visit Germany, France, Switzerland, and Italy. These journeys were recorded in his travelogues (旅行见闻). In 1835, Andersen published "Fairy Tales for Children," which contained four short stories. He eventually wrote around 168 fairy tales. They achieved success in his life-time and were widely published and translated.
Unhappiness also found its way into many of his tales which were not meant merely for children but for adults as well. He used very simple language and style. to disguise the moral teachings of his tales.
Andersen also wrote novels, plays and poems. He died at his home in Rolighed on August 4, 1875.
Andersen died on April 4, 1875.

Ways to Create Colors in a Photograph
There are two ways to create colors in a photograph. One method called additive, starts with three basic colors and adds them together to produce some other color. The second method called subtractive, starts with white light(a mixture of all colors in the spectrum(光谱))and by taking away some or all other colors, leaves the one desired.
In the additive method, separate colored lights combine to produce various other colors. The three additive primary colors are green, red and blue (each providing about one-third of the wavelengths in the total spectrum). Mixed in varying proportions, they can produce all colors. Green and red light mix to produce yellow, red and blue light mix to produce magenta (a purplish pink) ; green and blue mix to produce cyan (a bluish green). When equal parts of all three of these primary-colored beams of light overlap(重叠), the mixture appears white to the eye.
In the subtractive process colors are produced when dye(染料) absorbs some wavelengths and so passes on only part of the spectrum. The subtractive primaries are cyan, magenta and yellow; these primaries or dyes absorb red, green and blue wavelengths respectively, thus subtracting them from white light. These dye colors are the complementary colors to the three additive primaries of red, green and blue. Properly combined, the subtractive primaries can absorb all colors of light, producing black. But, mixed in varying proportions, they also can produce any color in the spectrum.
Whether 3 particular colors is obtained by adding colored lights together or by subtracting some light from the total spectrum, the result looks the same to the eye. The additive process was employed for early color photography. But the subtractive method, while requiring complex chemical techniques, has turned out to be more practical and is the basis of all modern color films.
