How is ag 1 used in photography

Their work is routinely published in magazines and newspapers. Fashion photography showcases and glamorizes fashion clothing, shoes, and accessories to make them more desirable to consumers. It is commonly published in magazines and online. People may choose this niche over different types of photography because of the opportunity to be highly creative in making photographs eye-catching and appealing.

Fashion photographers take a lot of full body shots and work in an array of locations, from fashion shows to studios with full lighting setups to city streets and open fields. They utilize many of the same skills as portrait photographers and must practice good teamwork and communication when working with shoot stylists, creative directors, and models.

By catching athletes, coaches, and even fans at the perfect moment, sports photographs can depict the passion, drama, and emotion that fuels sporting events. Sports photographers also usually use long, heavy lenses for zooming in on the action. Interesting angles can help make your work stand out in this competitive genre. Like it sounds, still life photography features inanimate objects—natural or manmade.

Still life photography can be artistic or commercial. It is commonly used in stock photography as well as product advertising. Each individual image tile is based on a 3. Tiles in the NAIP collection are natural color red, green, and blue bands or color near infra-red red, green, blue, and near infrared bands and may contain as much as 10 percent cloud cover per tile. The U. The JPEG format is a compressed file with embedded georeferencing information.

The lossy compression makes the file size smaller by reorganizing the data, but it also slightly degrades the imagery. APFO has stringent imagery compliance guidelines, and all deliverables are inspected using automated and visual methods to ensure accuracy and compliance with specifications. NAIP transitioned to an absolute accuracy specification beginning in , which tied the imagery to ground control points rather than existing orthorectified imagery.

Beginning in , all states flown adhered to this specification. The collections are located under the Aerial Photography category. Natural color aerial photographs acquired by a 35mm camera systems over 33 counties in eastern South Dakota. Digital images of orthorectified aerial photographs with a pixel resolution of 1-meter or finer from across the United States.

These products, as well as the agricultural methods used, may vary from one part of the world to another. Start of Agriculture Over centuries, the growth of agriculture contributed to the rise of civilizations.

Before agriculture became widespread, people spent most of their lives searching for food—hunting wild animals and gathering wild plants. About 11, years ago, people gradually learned how to grow cereal and root crops, and settled down to a life based on farming.

Scholars are not sure why this shift to farming took place, but it may have occurred because of climate change. When people began growing crops, they also began herding and breeding wild animals. Adapting wild plants and animals for people to use is called domestication. The first domesticated plant was probably rice or corn. Chinese farmers were cultivating rice as early as BCE. The first domesticated animals were dogs, which were used for hunting.

Sheep and goats were probably domesticated next. People also domesticated cattle and pigs. Most of these animals had once been hunted for hides and meat. Now many of them are also sources of milk, cheese, and butter.

Eventually, people used domesticated animals such as oxen for plowing, pulling, and transportation. Agriculture enabled people to produce surplus food. They could use this extra food when crops failed or trade it for other goods. Food surpluses allowed people to work at other tasks unrelated to farming.

Agriculture kept formerly nomadic people near their fields and led to the development of permanent villages. These became linked through trade. New economies were so successful in some areas that cities grew and civilizations developed.

The earliest civilizations based on intensive agriculture arose near the Tigris and Euphrates Rivers in Mesopotamia now Iraq and Iran and along the Nile River in Egypt. Improved Technology. For thousands of years, agricultural development was very slow. One of the earliest agricultural tools was fire. Native Americans used fire to control the growth of berry-producing plants, which they knew grew quickly after a wildfire. Farmers cultivated small plots of land by hand, using axes to clear away trees and digging sticks to break up and till the soil.

Over time, improved farming tools of bone, stone, bronze, and iron were developed. New methods of storage evolved. People began stockpiling foods in jars and clay-lined pits for use in times of scarcity. They also began making clay pots and other vessels for carrying and cooking food.

Around BCE, farmers in Mesopotamia developed simple irrigation systems. By channeling water from streams onto their fields, farmers were able to settle in areas once thought to be unsuited to agriculture. In Mesopotamia, and later in Egypt and China, people organized themselves and worked together to build and maintain better irrigation systems. Early farmers also developed improved varieties of plants. It was stronger than previous cereal grains; its hulls were easier to remove and it could be made into bread.

As the Romans expanded their empire, they adapted the best agricultural methods of the people they conquered. They wrote manuals about the farming techniques they observed in Africa and Asia, and adapted them to land in Europe.

The Chinese also adapted farming tools and methods from nearby empires. A variety of rice from Vietnam ripened quickly and allowed farmers to harvest several crops during a single growing season.

This rice quickly became popular throughout China. Many medieval European farmers used an open-field system of planting. One field would be planted in spring, another in autumn, and one would be left unplanted, or fallow. This system preserved nutrients in the soil, increasing crop production.

The leaders of the Islamic Golden Age which reached its height around in North Africa and the Middle East made agriculture into a science. Islamic Golden Age farmers learned crop rotation. In the 15th and 16th centuries, explorers introduced new varieties of plants and agricultural products into Europe. From Asia, they carried home coffee, tea, and indigo, a plant used to make blue dye.

From the Americas, they took plants such as potatoes, tomatoes, corn maize , beans, peanuts, and tobacco. Machinery A period of important agricultural development began in the early s for Great Britain and the Low Countries Belgium, Luxembourg, and the Netherlands, which lie below sea level.

New agricultural inventions dramatically increased food production in Europe and European colonies, particularly the United States and Canada. One of the most important of these developments was an improved horse-drawn seed drill invented by Jethro Tull in England. Until that time, farmers sowed seeds by hand.

By the end of the 18th century, seed drilling was widely practiced in Europe. Many machines were developed in the United States. The cotton gin, invented by Eli Whitney in , reduced the time needed to separate cotton fiber from seed. At about the same time, John and Hiram Pitts introduced a horse-powered thresher that shortened the process of separating grain and seed from chaff and straw. Along with new machines, there were several important advances in farming methods.

By selectively breeding animals breeding those with desirable traits , farmers increased the size and productivity of their livestock. Cultures have been breeding animals for centuries—evidence suggests Mongolian nomads were selectively breeding horses in the Bronze Age. Europeans began to practice selective breeding on a large scale beginning in the 18th century. An early example of this is the Leicester sheep, an animal selectively bred in England for its quality meat and long, coarse wool.

Plants could also be selectively bred for certain qualities. In experiments with pea plants, Mendel learned how traits were passed from one generation to the next. His work paved the way for improving crops through genetics. New crop rotation methods also evolved during this time. Many of these were adopted over the next century or so throughout Europe. For example, the Norfolk four-field system, developed in England, proved quite successful. It involved the yearly rotation of several crops, including wheat, turnips, barley, clover, and ryegrass.

This added nutrients to the soil, enabling farmers to grow enough to sell some of their harvest without having to leave any land unplanted. Most of the world was not affected by these developments, however. Agricultural Science In the early s, an average farmer in the U. How did this great leap in productivity come about?

It happened largely because of scientific advances and the development of new sources of power. By the late s, most farmers in developed countries were using both gasoline and electricity to power machinery. Tractors had replaced draft animals and steam-powered machinery. Farmers were using machines in almost every stage of cultivation and livestock management.

Electricity first became a power source on farms in Japan and Germany in the early s. By , most farms in the U. Electricity lit farm buildings and powered such machinery as water pumps, milking machines, and feeding equipment.

Today, electricity controls entire environments in livestock barns and poultry houses. Traditionally, farmers have used a variety of methods to protect their crops from pests and diseases.

They have put herb-based poisons on crops, handpicked insects off plants, bred strong varieties of crops, and rotated crops to control insects. Now, almost all farmers, especially in developed countries, rely on chemicals to control pests. With the use of chemicals, crop losses and prices have declined dramatically. For thousands of years, farmers relied on natural fertilizer —materials such as manure, wood ash, ground bones, fish or fish parts, and bird and bat waste called guano—to replenish or increase nutrients in the soil.

In the early s, scientists discovered which elements were most essential to plant growth: nitrogen, phosphorus, and potassium. Later, fertilizer containing these elements was manufactured in the U. Now, many farmers use chemical fertilizers with nitrates and phosphates because they greatly increase crop yields.

However, pesticides and fertilizers have come with another set of problems. The heavy reliance on chemicals has disturbed the environment, often destroying helpful species of animals along with harmful ones.

Chemical use may also pose a health hazard to people, especially through contaminated water supplies. Agricultural scientists are looking for safer chemicals to use as fertilizers and pesticides. Some farmers use natural controls and rely less on chemicals. Farming in Water Agriculture includes such forms of cultivation as hydroponics and aquaculture. Both involve farming in water.

Hydroponics is the science of growing plants in nutrient solutions. Just one acre of nutrient solution can yield more than 50 times the amount of lettuce grown on the same amount of soil. Aquaculture—primarily the cultivation of fish and shellfish—was practiced in China, India, and Egypt thousands of years ago. It is now used in lakes, ponds, the ocean, and other bodies of water throughout the world. Some forms of aquaculture, such as shrimp farming, have become important industries in many Asian and Latin American countries.

Climate change and improved technology are altering the way freshwater and ocean fisheries operate. Global warming has pushed warm-water species toward the poles and reduced the habitats of cold-water species. Traditional fishing communities in both developed and developing countries find the number of fish dwindling.

Bottom trawling has affected ocean ecosystems. In bottom trawling, enormous nets are strung from fishing boats and dragged at the bottom of the ocean. The nets catch halibut and squid, but also stir up sediment at the bottom of the ocean. This disturbs the marine life plankton and algae that forms the basis of the food chain. Genetic Modification For centuries, people have bred new types of plants and animals by random experimentation.

During the s and s, scientists developed new strains of high-yield wheat and rice. They introduced them into Mexico and parts of Asia.
