Sensors in digital cameras are not overly sensitive to UV light such as a movie, but the use of the UV filter will increase the color contrast of the images. The main function of the UV filter to protect the lens from scratches and impact. So if you do not use another filter, let alone the UV filter mounted on the lens.
2. Filter Neutral Density (ND). This filter is gray with various levels of concentration. Useful to reduce the intensity of light reaching the sensor. So it can shoot a longer exposure time. If you want to shoot slow speed during the daytime, ND filter is mandatory equipment.
3. Graduated ND filters. An ND filter with a density change gradually as gradation from dark to light. This filter is very useful for landscape photography in bright daylight. At the time of use, the more dense installed above, function to reduce the light from the sky and maintain the light from the mainland in order to obtain images with uneven illumination with blue sky.
4. Polarizer filter. Serves to reduce light reflection from non-metal surfaces. Very useful for shooting through the glass, such as shooting fish in aquariums or historical objects in the museum. This filter also improves contrast and color, as well as reduce light scattering. The effect was most apparent when used to photograph the clear sky with white clouds. Polarizer is very influential effect on the photo and can not be obtained through a digital process. There are 2 kinds of polarizer: linear polarizer with a straight line direction and circular polarizer (Pol Cir or CPL) which has the direction of the line of circular-polarizer viscosity can be adjusted by turning the front ring.
5. Filter Macro or Close Up. Function to change the focal length to allow for shooting an object with a very close distance. Also serves as a magnifying glass (magnifying glass). However, the use of a macro filter will take effect, such as lighting down 1-2 stops, reduced sharpness and DoF is narrower.
6. Filter Infra Red (IR). IR filter will pass infrared light and hold another spectrum of light. Basically, the camera sensor is designed to not be sensitive to IR light, thus causing the need for the use of IR filters lighting in a long time or a slow shutter speed.
7. Artistic filters or color. Provide shades usually associated with certain mood. For example, giving the impression of a cold blue color, while the color orange will give a warm impression. Yellow filter will enhance the contrast of the color of the sky and clouds. Currently, these shades can be added through the digital imaging process that is rarely used color filter

A long-term study and a large scale, in which involved more than 83,000 women showed that drinking 2 cups of coffee a day can cut the risk of stroke 20 percent lower than those who drank little or no coffee at all.

Suggestion: Drink between 2 to 4 cups of coffee per day, including moderate category. But if you suffer from insomnia, anxiety and fatigue, just drink one glass only.

2. Pomegranate juice

Lately, the pomegranate juice reputation soar and mesmerize nutrition researchers. Why not, the experts from the University of California found that the antioxidant capacity of pomegranate juice three times higher than red wine and green tea. Even early research suggests, regular consumption of pomegranate juice may lower cholesterol, reduce arterial plaque (a risk factor for heart disease), and increases blood flow to the heart.

Suggestion: If possible, avoid additional sweetener when making pomegranate juice.

3. Red wine (red wine)

Red wine contains many compounds that can protect heart health, including resveratrol. Resveratrol has antioxidant properties that can protect blood vessels in the heart and help prevent the formation of blood clots. Some evidence also showed that consumption of red wine in moderate amounts can increase HDL (good cholesterol).

Suggestion: For women, it is recommended no more than 1.5 cups per day. As for the men, no more than 2 cups.

4. Black tea

Black tea is produced through the fermentation process after the leaves are harvested and dried. This processing change the chemical composition of the leaves, so as to produce a powerful antioxidant that helps support cardiovascular health. Black tea has been shown to reduce the risk of stroke, reduce LDL (bad) cholesterol, improve blood vessel function, and increases blood flow in the coronary arteries.

Tip: The longer you dip the tea, the greater the benefits derived phytochemicals. Therefore, serve tea with hot water will be much better while maintaining antioxidant content is maintained. Drinking several cups of black tea every day can help reduce the risk of heart disease.

5. Green tea

A 2004 study suggests that drinking green tea in large amounts can prevent the risk of coronary artery disease. There are many studies linking green tea consumption with lower cholesterol, prevention of blood clots and stroke.

Suggestion: Drink 1-3 cups of green tea a day.

6. Water

Dehydration can contribute to multiple risk factors for coronary heart disease, including gore. When you're dehydrated, blood would be more viscous. This condition causes your heart to expend more energy to pump blood throughout the body. In fact, chronic dehydration can cause hypertension (high blood pressure).

Suggestion: Many experts recommend at least a day a person should drink 8-10 glasses of water (for adults). But the number of recommendations that should be taken not to apply to every person and every condition. To be sure, do not let your body get dehydrated. You can also add juice or lemon juice into warm water to add flavor as well as decay and obtain the benefits of antioxidants.

Outlook not affected the decrease in the Real Sector

Bank Danamon chief economist Anton Gunawan, said the decline in Indonesian debt outlook by rating agency Standard & Poor's (S & P) will not have an impact on economic growth in Indonesia. "If later slowed his growth was not because of ratings, but there are other factors, such as policy horticulture and later rising fuel policy," he said when contacted by Tempo, Monday, May 6, 2013.

He explains the decrease in outlook by S & P is more affected than the financial to the real sector. Seen from declining Composite Stock Price Index (CSPI) after the results were announced this rating. "Our economy is no improvement, the S & P is late, a bit odd. Weighting of the risk they are considered to increase the views of policies rather backwards. However, the effect only until this week. Next week is not, "said Anton.

Anton added a drop outlook is also not so affected the company. According to him, there are the results of the Japanese agency which is used as a reference by investors from Japan and outside Japan to invest in Indonesia. "Investment grade Rating from Japan enough to help investors in Indonesia," he said.

In addition to the rating, another reference to outside investors to infuse capital, the opportunity to earn a high return. To obtain the opportunity, they look like the easiness of adequate infrastructure, tax treatment, labor pressures are low, and the level of corruption is small. "It is used as a reference by investors. Rating is just one variable, "he said.

The same statement also expressed by economist of Standard Chartered, Erick Sugandi. According to him, the downgrade by S & P more than the financial impact on the real sector. "It's only temporary. I guess this week was able to get back to normal, "he said when contacted by Tempo, Monday, May 6, 2013.

According to him, the market also needs projection. Issues such as these can be used. This is the time to make the JCI shaken, which is down 1.4 per cent at the close of last week.

As for the real sector, Erick said he would not have the slightest impact. "Foreign Investment logged in Indonesia because the market still has potential with the achievement of the government in the form of infrastructure development albeit slowly, but it is progress," said Erick.
