Sumit Kumar Bhalotia: Types of Photography

   Sumit Kumar bhalotia: Nature Photography

It is a combination of different types of photography techniques which provides the viewer a message in the form of art. It’s all about the right angle, correct lighting and great lens. For different types of photos, the lens has to be changed accordingly. You can see a lot of people taking pictures on their cameras and mobile phones, if you want your photo to stand out from the rest, then you should have some knowledge of different types of photography. Sumit kumar bhalotia describing some different types of photography here. Let us look through the different types of photography styles to inspire you.

 Landscape Photography

If you love photography and have the tendency to stop and look at the beautiful scenery around you and freeze nature in one picture, you are definitely a type of photographer interested in the type of photography called landscape photography.

Portrait Photography

One of the oldest types of photography is portrait photography. It can range from shooting your family members to friends to pets. It is often called portraiture and this type of photographer abounds.

Aerial photography

Aerial photography is that kind of photography where pictures are captures from a higher altitude such as planes, air balloons, parachutes and skyscrapers. These pictures provide a larger view of the subject and its background.

Architectural Photography

This type of photography deals with taking shots of structures, houses and buildings from different angles. The main purpose of architectural photography is to create a positive impact on potential real estate buyers.

 Wedding Photography/Event Photography

It is said that a newcomer in professional photography begins his/her career by practicing a wedding orevent photography. But that does not mean that this type of photographer does not require and any skill. A person dealing in this type of photography has to be an expert in portraiture and extremely good editing skills. The demand for wedding photography or event photography is more.

Sports Photography

This genre of photography specializes in capturing a decisive moment in an event of sports. Sports photography is one of the difficult types of photography. It requires practice along with the various equipments.

Wildlife Photography

The genre of photography that focuses on animals and their natural habitat is called wildlife photography. Animal behaviors in wild are also capture by wildlife photographer. Mostly these pictures are captured to be printed in journals or exhibitions. Many people practice this type of photography. Apart from a good camera, several lens, strong flashlight, you need patience to click the right picture.

Antarctic ice loss increased dramatically

           Antarctic ice loss increased dramatically

 You may have heard about global warming. It seems that in the last 100 years the earth’s temperature has increased about half a degree Celsius. This may not sound like much, but even half a degree can have an effect on our planet. This higher temperature may be causing some floatingicebergs to melt, but this will not make the oceans rise. Icebergs are large floating chunks of ice. In order to float, the iceberg displaces a volume of water that has a weight equal to that of the iceberg.

Recently in one study it is found that Melting of floating ice shelves around the continent is accelerating, potentially unlocking extra sea level rise from larger ice sheets jammed behind them. The ice around the edge of Antarctica is melting faster than previously thought, potentially unlocking metres of sea-level rise in the long-term, researchers have warned.

A team of US scientists looked at 18 years’ worth of satellite data and found the floating ice shelves that skirt the continent are losing 310km3 of ice every year. One shelf lost 18% of its thickness during the period.

The loss of ice shelves does not contribute much directly to sea level rise. But they act like a cork in a bottle at the point where glaciers meet the sea – jamming the flow of ice from the massive ice sheets of east and west Antarctica.

Over the past decade the loss of ice shelf volume in Antarctica increased from 25km3 to 310km3 every year.

It is unclear whether the loss of ice is directly related to man-made climate change or a cyclical change in ocean currents. But the extra sea level rise from ice sheets will exacerbate the rise caused by the expansion of oceans as the world warms.

Professor David Vaughan, director of science at BAS, said the findings would help scientists to make more accurate predictions about future sea level rise.

The western coast ice shelves contributed the majority of the ice loss. The rate of loss increased by 70% in the last decade. Two shelves in this region could completely disappear within a century. Conversely, there were some areas in east Antarctica where the shelves stayed stable or grew slightly. Vaughan said the regional variations were predicted by previous studies.

Holland said it was important not to confuse floating ice sheets, which can be up to 2km thick, with the much thinner sea ice. The one metre thick layer of sea ice around Antarctica has been expanding in recent decades, which some scientists think is because of increasing polar winds, which push the ice further out.

ALS treatment found in three proteins

Amyotrophic lateral sclerosis (ALS), often referred to as “Lou Gehrig’s Disease,” is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.

Were ALS comes from and how it progresses are mysteries that continue to vex medical science. But recent research at Sweden’s KTH Royal Institute of Technology has found three proteins that could shed some light on the mechanisms behind this deadly disease. In the search for treatments and earlier diagnoses of ALS, scientists are focused on biomarkers, or biological characteristics that reflect a physiological change in the body during or after an illness. A typical example of a biomarker is troponin, which is secreted into the blood when a heart muscle is damaged following a heart attack. There are currently no reliable markers for ALS, or amyotrophic lateral sclerosis, a progressive neurodegenerative diseasethat destroys the nerve cells that control muscle movement, causing muscles to become weak and then paralyzed. ALS affects all skeletal muscles, including those used for breathing and swallowing.

Häggmark explains that one protein, NEFM, is a structural component of neurons in the central and peripheral nervous system. If found in blood plasma, it could indicate nerve fiber death as a result of ALS.

RGS18, on the other hand, is a cell signaling protein. The increase of this protein may reflect its leakage from the degenerated muscles in these patients, the study states.

The third protein, SLC25A20, is a mitochondrial protein thereby representing a cellular structure that that has previously been shown as linked to ALS.

 Häggmark says the ongoing study will include examining “disease specificity” of the markers, that is, whether what they find in ALS is also relevant for other neurological degenerative diseases, such as multiple sclerosis.
