HD Nature Photos Information

Source(google.com.pk)
Nature photography focuses on landscapes, natural world and plant life as they are found in their natural environment. Photographs of nature provide glimpses of animals, forests or mountains that may not be seen in person. Many nature photographers try to educate people about the beauty of nature, often with the hope that more people will be inspired to help the environment.

The goal of a nature photographer is to photograph his subject with the least amount of disruption to the subject's environment. The photographer should not cause destruction, harming the flora or fauna, in his attempt to photograph his subject. It also is not advised to try and interact with wild animals or attempt to manipulate a subject to obtain the desired shot. The end result should be an accurate presentation of the animal's or plants natural state.

Nature photographers require a camera that gives them total control over camera settings. The photographer cannot rely on the camera's internal light meter and needs to be able to manipulate the shutter speed and aperture manually. A wide-angle zoom lens and a telephoto zoom lens are two lenses most nature photographers use. It's generally recommended to purchase lenses made by the camera manufacturer rather than buy cheaper third party lenses. Tripods are necessary to obtain the sharpest quality image in any lighting situation.

Nature photography encompasses all forms of photography where the main subject has something to do with nature. Some of the more common types of nature photography include photographing wild animals, plants and flowers, in their natural environment as well as landscapes. Other types of nature photography include celestial bodies such as the sun, moon, and stars; insects and arachnids; and underwater creatures.

High-definition video is video of higher resolution than is standard. While there is no specific meaning for high-definition, generally any video image with more than 480 horizontal lines (North America) or 570 lines (Europe) is considered high-definition. 720 scan lines is generally the minimum even though many systems greatly exceed that. Images of standard resolution captured at rates faster than normal (60 frames/second North America, 50 fps Europe), by a high-speed camera may be considered high-definition in some contexts.

From a historical perspective, the first electronic scanning format 405 lines was the first "high definition" television system as the previous mechanical systems had far fewer scanning lines.

From 1939, the US and other European countries experimented with 441 lines and 605 lines until, in 1941, the Federal Communications Commission (FCC) mandated 525 lines for the US. In wartime France, René Barthélemy experimented with higher definitions, reaching 1015 and even 1042 lines. Official French transmissions finally began with 819 lines in late 1949; however, this standard was abandoned in 1984 upon the adoption of 625-line color on the TF1 network.

Modern HD specifications date to the early 1970s, when Japanese engineers developed the HighVision 1,125-line interlaced TV standard (also called MUSE) that ran at 60 frames per second. The Sony HDVS system was presented at an international meeting of television engineers in Algiers, April 1981 and Japan's NHK presented its analog HDTV system at a Swiss conference in 1983.
The NHK system was standardized in the United States as Society of Motion Picture and Television Engineers (SMPTE) standard #240M in the early 1990s, but abandoned later on when it was replaced by a DVB analog standard. HighVision video is still usable for HDTV video interchange, but there is almost no equipment around to perform this function. Attempts at shoehorning in HighVision into a 6 MHz broadcast channel were mostly unsuccessful. All attempts at using this format for terrestrial TV transmission were forsaken by the mid-1990s.

Europe developed HD-MAC (1,250 lines, 50 Hz), a member of the MAC family of hybrid analogue/digital video standards; however, it never took off as a terrestrial video transmission format. HD-MAC was never designated for video interchange except by the European Broadcasting Union.

The current high-definition video standards in North America were developed during the course of the advanced television process initiated by the Federal Communications Commission in 1987 at the request of American broadcasters. In essence, the end of the 1980s was a death knell for most analog high definition technologies that had developed up to that time.
