What's All The Fuss About City Landscape Photos

This article attempts to open up some of the reasons city landscape photography is becoming popular and why it is that much different from normal photography. City landscape photography is indeed special but is it all that different after all? Let's go into this bit by bit and find out.

When we visit a city for the first time most of us are willing to spend a lot of money on books or postcards that contain city landscape photos. Often, just looking at city landscape photos might determine that you go and visit that city. Its obvious that city landscape photography is captivating for most of us.

City landscape photography might be also regarded as the art of selling that specific place, that city, of sharing its beauty to people all around the world, of encouraging them to visit that place and (why not?) spend money there.

Making a city landscape photo is not very difficult. Of course, you need the proper equipment and you must have a clear idea of what you intend to suggest in your photo and what is it that you want to capture. You also have to choose the viewpoint; sometimes elevated viewpoints are a clear advantage in city landscape photography. You must also think about what kind of light is best in expressing your idea and how the weather should be. You might need a lot of time for taking a single excellent photo, especially if the weather is unstable, because it might be difficult to naturally obtain the best light or the proper shadows.

If you simply want to capture something that would be representative for the city, then you can just photograph the most famous places in the city, such as the London Bridge in London, the skyline in Manhattan or The Eiffel Tower in Paris. But the disadvantage in photographing these classical tourist sights is that its almost impossible to create an original work, as there are thousands of these city landscape photos already taken.

If you intend to attract tourists with your city landscape photos, you need to cosmeticize the image (imagine Broadway with papers thrown on the ground) and present it in the desired manner: postcard, poster, exposition, etc. City landscape photography becomes an art when its purpose is not selling anything, but just showing the beauty of those places. Black and white or sepia photos are sometimes much more interesting and suggestive than the colored ones.

When you photograph a city landscape, you basically try to catch the essence of the place youre immortalizing. There are two ways to achieve this. You can photograph single buildings or large areas of buildings or you can photograph people in that city in their daily activities. The city has an important role in the development of the individuals living there, and the individuals influence different aspects of the city, in return. This is why it is interesting to capture the interaction between the city and the people living there.

City landscape photos might also have other purposes, such as a charity purpose. For instance, you can photograph homeless children in Bucharest (Romania) if you want to draw attention to the fact that they exist and should not be ignored, but indeed they should be helped to integrate into society. Thats a photographic contribution.

When you choose the places you want to photograph, you must think of the significance those places have for the city inhabitants. It is not difficult to observe that places with great importance for the ones who live in the city (from cultural, historical, social or economical points of view) are also significant for tourists. If all the Parisians walk on Champs Elise, then tourists will walk on Champs Elise. Therefore its likely, a beautiful city landscape photo of that boulevard will have the power to attract more tourists there.

Considering that a pictures worth a thousand words, it is obvious that city landscape photos are one of the best ways to represent a city. Is it enough to look at a city landscape photo of New York that I will then want to go and visit that city, if thats what the photographer wants me to feel? On the contrary, after seeing a carefully thought-out photo with street children in Bucharest, it is unlikely that I will have a desire to visit NY at that very point in time, but I might be impressed and saddened by that image of Bucharest and want to help them in some way. Having said that, this is not the same with all people but you will be amazed at the power a photographer can have with city landscape photo skills. Think carefully about the image before shooting away.

Space Sunshade May One Day Reduce Global Warming

Global warming is a reality and increasingly its consequences are upon us. We may think that global warming does not affect us but the fact is it has already started to have disastrous consequences. Flash floods, droughts, receding icebergs, cyclones are some of the manifestations of global warming. Although we are aware and worried about it and trying our best to control it but no significant impact could be seen.

Scientists have come up with new strategies to tackle the problem. Now a scientist has suggested an ambitious idea to contain global warming. Put sunshades in space. Thats right. University of Arizona astronomer Roger Angel suggests putting sunshades in space and has detailed his idea in a paper Feasibility of cooling the Earth with a cloud of small spacecraft near L1 in the Proceedings of the National Academy of Sciences. He suggests launching a constellation of trillions of small free-flying spacecraft a million miles above Earth into an orbit aligned with the sun, called the L-1 orbit.

This spacecraft would form a long, cylindrical cloud and would have a diameter about half that of Earth, and about 10 times longer. It is suggested that about 10 percent of the sunlight passing through the 60,000-mile length of the cloud, pointing lengthwise between the Earth and the sun, would be diverted away from our planet. This would result in uniformly reduced sunlight by about 2 percent over the entire planet and would balance the heating of carbon dioxide in Earth's atmosphere.

The use of space shade was first mooted by James Early of the Lawrence Livermore National Laboratory in 1989.

"The earlier ideas were for bigger, heavier structures that would have needed manufacture and launch from the moon, which is pretty futuristic," Angel said. "I wanted to make the sunshade from small 'flyers,' small, light and extremely thin spacecraft that could be completely assembled and launched from Earth, in stacks of a million at a time. When they reached L1, they would be dealt off the stack into a cloud. There's nothing to assemble in space."

Angel proposes to design lightweight flyers made of transparent film pierced with small holes and would be two feet in diameter, 1/5000 of an inch thick and weigh about a gram, the same as a large butterfly. He suggests using MEMS technology mirrors as tiny sails that tilt to hold the flyers position in the orbiting constellation.

The weight of all flyers would be 20 millions tons. But conventional rocket launch system at $10,000 a pound would be too prohibitive. His alternative would cost only around $20 a pound.

He suggests deploying a total 20 electromagnetic launchers launching a stack of flyers every 5 minutes for 10 years. The electromagnetic launchers would use hydroelectric power but even if it uses coal-generated electricity, each ton of carbon used would reduce the effect of 1000 tons of atmospheric carbon.

Once propelled beyond Earths atmosphere the flyer stacks would be steered to L-1 orbit by solar-powered ion propulsion, pioneered by European Space Agency's SMART-1 moon orbiter and NASA's Deep Space 1 probe.

"The concept builds on existing technologies," Angel said. "It seems feasible that it could be developed and deployed in about 25 years at a cost of a few trillion dollars. With care, the solar shade should last about 50 years. So the average cost is about $100 billion a year, or about two-tenths of one percent of the global domestic product."

He added, "The sunshade is no substitute for developing renewable energy, the only permanent solution. A similar massive level of technological innovation and financial investment could ensure that.

"But if the planet gets into an abrupt climate crisis that can only be fixed by cooling, it would be good to be ready with some shading solutions that have been worked out."
