Sun Goes Down

Sunset always being a beautiful object for who enjoy the beauty of nature. I try to catch the sunset picture from different angle. not really bad i think for an amateur photograph :)

Observation of Sunlight

Sunlight is very bright, and looking directly at the Sun with the naked eye for brief periods can be painful, but is not particularly hazardous for normal, non-dilated eyes. Looking directly at the Sun causes phosphene visual artifacts and temporary partial blindness. It also delivers about 4 milliwatts of sunlight to the retina, slightly heating it and potentially causing damage in eyes that cannot respond properly to the brightness. UV exposure gradually yellows the lens of the eye over a period of years and is thought to contribute to the formation of cataracts, but this depends on general exposure to solar UV, not on whether one looks directly at the Sun. Long-duration viewing of the direct Sun with the naked eye can begin to cause UV-induced, sunburn-like lesions on the retina after about 100 seconds, particularly under conditions where the UV light from the Sun is intense and well focused conditions are worsened by young eyes or new lens implants (which admit more UV than aging natural eyes), Sun angles near the zenith, and observing locations at high altitude.

Viewing the Sun through light-concentrating optics such as binoculars is very hazardous without an appropriate filter that blocks UV and substantially dims the sunlight. An attenuating (ND) filter might not filter UV and so is still dangerous. Unfiltered binoculars can deliver over 500 times as much energy to the retina as using the naked eye, killing retinal cells almost instantly (even though the power per unit area of image on the retina is the same, the heat cannot dissipate fast enough because the image is larger). Even brief glances at the midday Sun through unfiltered binoculars can cause permanent blindness. One way to view the Sun safely is by projecting its image onto a screen using a telescope and eyepiece without cemented elements. This should only be done with a small refracting telescope (or binoculars) with a clean eyepiece. Other kinds of telescopes can be damaged by this procedure.

Scenery of Sun Phenomenon ( Autumal Equinox)

I just shoot this pic several minutes ago. My office was stirred by this phenomenon. Many people go to outside and try to shoot it So do i.. :)

Although the sun hitting my skin, it didn't make my spirit down because i just wanna take it and post to my blog, so that all of you can also see the beautiful of nature.

what is autumal equinox?
here is the explanation i read from wikianswer

The date (near September 22 in the northern hemisphere) when night and day are nearly of the same length and Sun crosses the celestial equator (i.e., declination 0) moving southward (in the northern hemisphere). In the southern hemisphere, the autumnal equinox corresponds to the center of the Sun crossing the celestial equator moving northward and occurs on the date of the northern vernal equinox. The autumnal equinox marks the first day of the season of autumn.

Shining sun

I try to take a sun photo in the middle of the day.
i wonder what kind of view that i can see because i can't see anything when i try to shoot it.
finally, i got it.
A beautiful view of the shining sun.

Sunset

Although when the sun will disappear at the end of the day, it always give a beautiful sight to fill us with wonder.

Barrier

Although the dark clouds floated across the sun,it will not prevent the sun to keep on rising.
Keep trying whatever the barriers are, just across it to reach your dreams.

colorful day

As the sun rising and radiating a warm cosy glow, it's time to you to fill your day
with colorful day.Always try to make your life better than yesterday.
