The Sizes of Sakura Trees

The sizes of sakura trees differ depending on the variety. For instance, the Japanese cherry or Prunus serrulata can reach the average height of 8 meters to 12 meters. Each of its leaves can grow as long as 5 to 13 centimeters and as wide as 2.5 to 6.5 centimeters. The average diameter of its fruit is 8 to 10 millimeters.

Another beautiful variety is the Oshima cherry or Prunus speciosa. As a deciduous tree, it can grow as high as 4 to 12 meters. Each leaf can grow up to 5 to 10 centimeters long and 3 to 6 centimeters wide. Meanwhile, the average diameter of its flowers ranges from 2.5 to 4 centimeters. It bears a small black cherry as a fruit, the diameter of which is about 1 centimeter. An 800-year old tree can be found on Oshima Island, the circumference of which is measured at 8 meters.

The Sargent’s cherry or Prunus sargentii is another interesting variant, which grows at an average height of 6.09 to 12.19 meters. Likewise, it has a crown that spreads at an average of 6.09 to 12.19 meters. Each of its leaves can grow as long as 7.62 to 12.7 centimeters.

Digital Camera

A digital camera (also digicam or camera for short) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.

Many compact digital still cameras can record sound and moving video as well as still photographs. Most 21st century cameras are digital.[1]

Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space. Some can crop pictures and perform other elementary image editing. The optical system works the same as in film cameras, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, just as with film but the image pickup device is electronic rather than chemical.

Digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. The Hubble Space Telescope and other astronomical devices are essentially specialized digital cameras.

Photography

Method of recording permanent images by the action of light projected by a lens in a camera onto a film or other light-sensitive material. It was developed in the 19th century through the artistic aspirations of two Frenchmen, Nicéphore Niepce and Louis-Jacques-Mandé Daguerre, whose combined discoveries led to the invention of the first commercially successful process, the daguerreotype (1837). In addition, two Englishmen, Thomas Wedgwood and William Henry Fox Talbot, patented the negative-positive calotype process (1839) that became the forerunner of modern photographic technique. Photography was initially used for portraiture and landscapes. In the 1850s and '60s, Mathew B. Brady and Roger Fenton pioneered war photography and photojournalism. From its inception, two views of photography predominated: one approach held that the camera and its resulting images truthfully document the real world, while the other considered the camera simply to be a tool, much like a paintbrush, with which to create artistic statements. The latter notion, known as Pictorialism, held sway from the late 1860s through the first decade of the 20th century, as photographers manipulated their negatives and prints to create hazy, elaborately staged images that resembled paintings. By the 1920s and '30s, a new, more realistic style of photography gained prominence, as photographers such as Paul Strand, Edward Weston, and Ansel Adams began to pursue sharply focused, detailed images. The Great Depression and two world wars inspired many photographers, including Walker Evans and Dorothea Lange, to pursue documentary, often socially conscious photography. Inspired by such work, many photojournalists, including Alfred Eisenstaedt and Margaret Bourke-White, also emerged during this period. In the second half of the 20th century, the urban social scene became a subject of much interest to photographers, as did celebrity portraiture and fashion photography. At the turn of the 21st century, photographers took advantage of digital capabilities by experimenting with enormous formats and new manipulative techniques. As technological advances improve photographic equipment, materials, and techniques, the scope of photography continues to expand enormously.
