http://www.youtube.com/playlist?list=PLSKnEDIbkcptjl3DB8VyxyUxbSfHAfDdV, Classical Music - artistic genre of music that originated from the Western liturgical and secular music around the eleventh century. and popular to this day. Classical music standards developed between 1550-1900 m.Klasikal church music and secular. Church came from church hymns, psalms, and secular - the harmonized dance, folk melodies. However, a frequent composer have formed both types of music. Classical music is instrumental and vocal. Instrumental classical music is generally performs Symphony Orchestra. The main instruments used are strings (violin, viola, cello, double bass), wooden wind instruments (flute, oboe, clarinet, bassoon), brass wind instruments (trumpet, trombone, tuba, French horn), percussion (mostly timpano). Use of electronic instruments are usually not considered to be classical music. Vocal part by the opera singer or choir. If the main form of popular music is a song that classical music has a variety of performance forms, symphony, concert, oratorio, opera, sonata, fugue, suite. Lengthy compositions, musical harmony, the mood is changing.

Photography - conservation technology in mechanical, chemical or digital techniques. The word comes from the Greek words φως Phos ("light") and γραφις graphs ("brush"), which also means drawing with light. This term is in English and German language came into use in 1839. February Experimental period (1820-1840 m). Chalon - sur - Saone, in J. N. Niepce'as since 1813. improved recently invented lithography method. He hoped to create such a manner that "painted" a lithographic chalk, and light. About 1827. He has used the term heliografija (sun drawing), and photographs describing the engravings copying tools. In 1829. December Niepce'as begin to cooperate with L. J. M. Daguerre'u, a former set designer, who in 1822. invented the diorama (an improved version of the panoramic imaging). Daguerre'as discovered that invisible images obtained using silver iodide to highlight the vapor of silver. Logging plates immersed in a hot aqueous salt solution. The first successful dagerotipija made ​​in 1837. Fox Talbot, English scientist and naturalist, in 1833. began testing in order to capture the images onto photosensitive paper. As a developer using gallium acid. Produced by negative, which, covered with wax, to make transparent, and of his receiving a transparent positive prints. Talbot became a pioneer in photographic printing. The method, which produces images kalotipiniai talbotipiniai or became publicly known in 1839. fotogeninis as drawing, and 1841. he patented. Shooting light enters the camera through the lens of the lens system. Adjusting the lens position changing image, the camera focuses in the cell. Top, a variable focal length lens allows not only the "focus" (make bold) scene, but it is closer (in fact at the time the picture angle is reduced, while the approximate them "object has a growing part of the picture area). As long as the camera shutter is open, the light falls on the film negative or other light-sensitive material and affects the light-sensitive elements, as recorded in the image. This process is controlled by two main parameters of photos - and the retention of the diaphragm. Exposure is usually expressed in seconds or parts of a second greatest impact on the amount of light entering fotoaratą. Possible values ​​depend on the maintenance of the same camera and lens replacement does not change. Since the maintenance of brightness and sharpness of moving objects in the picture. The longer the exposure - look at the brighter objects photographed (using a long exposure night images and the like), but will be obscured or completely fused moving objects and people. Exposure photography is combined with the choice of film sensitivity. Film sensitivity is the most important film parameter. It is the manufacturer and depends on the chemical reaction to light qualities. The higher the number, indicating the sensitivity of the strip, the less light (less maintenance, narrower aperture) it needs to capture the same image brightness. This particular lens aperture, forming a variable-diameter hole in the light to enter. It is measured in so called f-numbers identifying the relative aperture of the lens diameter and length ratios. Unlike maintenance, possible difragmos setting options are limited and depends on the lens. Large aperture - the number refers to the narrow beam to get a hole in shooting - from the picture is dark (no maintenance), but even at different distances from the camera in the object will look quite sharp. Meanwhile, a small f - number representing the diagram is widely useful light to spend more light into the picture, but only to highlight and focused at the same distance of the objects - everything else will be noticeably blurry. Later film is affected by chemical means (development) and the image triggered the creation of a positive or negative. After the light projected through a negative (positive) onto light-sensitive paper, create a color or black and white black and white picture - a picture (photograph).
