Additionally, modern continuous ring lights allow for precise control of bright light without the harshness of a traditional ring flash, giving you more flexibility in various settings. The best ring lights even come with adjustable brightness levels and fill lighting features to help balance between natural light and artificial lighting, ensuring a seamless blend of both.
Another benefit is that most modern ring lights come with continuous lighting capabilities, thanks to LED technology. This means that you can adjust the brightness and color temperature of the light, ensuring that your subject is illuminated in the most flattering way possible. LED ring lights also tend to last longer and are more energy-efficient compared to traditional studio lights or ring flashes.
A ring light is exactly what it sounds like: a circular lighting device that surrounds the camera lens or is positioned in front of the subject. This unique shape allows the light to illuminate the subject evenly, which reduces shadows and creates a flattering, soft light.Â
Originally used in medical and dental photography, ring lights have gained immense popularity in recent years, especially among content creators and portrait photographers. Whether you're shooting a YouTube video, capturing a perfect selfie, or filming a live stream, ring lights offer an easy way to achieve professional-quality lighting with minimal effort.

Ground based infrared observatories, using advanced techniques such as Adaptive Optics are providing fascinating views of the infrared Universe viewed through our atmosphere's infrared windows. Mauna Kea Observatories Although these observatories cannot view at other infrared wavelengths, they can observe the near-infrared sky almost anytime the weather permits, providing valuable long term studies of objects in space. New missions are being planned to get above the atmosphere to observe the infrared Universe with better resolution than ever before. SOFIA, an airborne observatory, is schedule to start operations in 2004. SIRTF (the Space Infrared Telescope Facility) will be NASA's next great observatory in space. In the next decade, you will probably hear much news about discoveries being made in infrared astronomy, as we now can see beyond our atmosphere's infrared windows!

The main reason why ring lights are so popular is that they provide a natural-looking fill light that enhances the subject without creating harsh shadows. Unlike other light sources that can be too bright or uneven, ring lights distribute light in a circular pattern, which creates a soft, even glow. This is particularly helpful in portrait photography and video shoots, where harsh lighting can make a subject's face appear flat or washed out.
From the table below, you can see that only a few of the infrared "windows" have both high sky transparency and low sky emission. These infrared windows are mainly at infrared wavelengths below 4 microns. Infrared Windows in the Atmosphere Wavelength Range Band Sky Transparency Sky Brightness 1.1 - 1.4 microns J high low at night 1.5 - 1.8 microns H high very low 2.0 - 2.4 microns K high very low 3.0 - 4.0 microns L 3.0 - 3.5 microns: fair 3.5 - 4.0 microns: high low 4.6 - 5.0 microns M low high 7.5 - 14.5 microns N 8 - 9 microns and 10 -12 microns: fair others: low very high 17 - 40 microns 17 - 25 microns: Q 28 - 40 microns: Z very low very high 330 - 370 microns very low low Basically, everything we have learned about the Universe comes from studying the light or electromagnetic radiation emitted by objects in space. To get a complete picture of the Universe, we need to see it in all of its light, at all wavelengths. This is why it is so important to send observatories into space, to get above our atmosphere which prevents so much of this valuable information from reaching us. Since most infrared light is blocked by our atmosphere, infrared astronomers have placed instruments onboard, rockets, balloons, aircraft and space telescopes to view regions of the infrared which are not detectable from the ground. As a result, amazing discoveries about our Universe have been made and hundreds of thousands of new astronomical sources have been detected for the first time.

Most of the infrared light coming to us from the Universe is absorbed by water vapor and carbon dioxide in the Earth's atmosphere. Only in a few narrow wavelength ranges, can infrared light make it through (at least partially) to a ground based infrared telescope. The Earth's atmosphere causes another problem for infrared astronomers. The atmosphere itself radiates strongly in the infrared, often putting out more infrared light than the object in space being observed. This atmospheric infrared emission peaks at a wavelength of about 10 microns (micron is short for a micrometer or one millionth of a meter). So the best view of the infrared universe, from ground based telescopes, are at infrared wavelengths which can pass through the Earth's atmosphere and at which the atmosphere is dim in the infrared. Ground based infrared observatories are usually placed near the summit of high, dry mountains to get above as much of the atmosphere as possible. Even so, most infrared wavelengths are completely absorbed by the atmosphere and never make it to the ground. From the table below, you can see that only a few of the infrared "windows" have both high sky transparency and low sky emission.

For larger projects or professional setups, consider investing in larger ring lights. These provide a broader range of illumination, which can be crucial for capturing more complex scenes or working in dimly lit environments. Larger lights also offer better control over the lighting, making it easier to manage shadows and ensure that every detail is well-lit.
The Universe sends us light at all wavelengths of the electromagnetic spectrum. However, most of this light does not reach us at ground level here on Earth. Why? Because we have an atmosphere which blocks out many types of radiation while letting other types through. Fortunately for life on Earth, our atmosphere blocks out harmful, high energy radiation like X-rays, gamma rays and most of the ultraviolet rays. It also block out most infrared radiation, as well as very low energy radio waves. On the other hand, our atmosphere lets visible light, most radio waves, and small wavelength ranges of infrared light through, allowing astronomers to view the Universe at these wavelengths. Most of the infrared light coming to us from the Universe is absorbed by water vapor and carbon dioxide in the Earth's atmosphere. Only in a few narrow wavelength ranges, can infrared light make it through (at least partially) to a ground based infrared telescope.

When it comes to photography, videography, or content creation, good lighting can make all the difference. It can enhance your subject, create mood, and eliminate harsh shadows that may ruin your shot. Enter the ring light, an essential tool for many photographers, videographers, and content creators who need reliable, balanced lighting. But how exactly do you use a ring light to get those perfectly lit shots?

The Earth's atmosphere causes another problem for infrared astronomers. The atmosphere itself radiates strongly in the infrared, often putting out more infrared light than the object in space being observed. This atmospheric infrared emission peaks at a wavelength of about 10 microns (micron is short for a micrometer or one millionth of a meter). So the best view of the infrared universe, from ground based telescopes, are at infrared wavelengths which can pass through the Earth's atmosphere and at which the atmosphere is dim in the infrared. Ground based infrared observatories are usually placed near the summit of high, dry mountains to get above as much of the atmosphere as possible. Even so, most infrared wavelengths are completely absorbed by the atmosphere and never make it to the ground. From the table below, you can see that only a few of the infrared "windows" have both high sky transparency and low sky emission. These infrared windows are mainly at infrared wavelengths below 4 microns. Infrared Windows in the Atmosphere Wavelength Range Band Sky Transparency Sky Brightness 1.1 - 1.4 microns J high low at night 1.5 - 1.8 microns H high very low 2.0 - 2.4 microns K high very low 3.0 - 4.0 microns L 3.0 - 3.5 microns: fair 3.5 - 4.0 microns: high low 4.6 - 5.0 microns M low high 7.5 - 14.5 microns N 8 - 9 microns and 10 -12 microns: fair others: low very high 17 - 40 microns 17 - 25 microns: Q 28 - 40 microns: Z very low very high 330 - 370 microns very low low Basically, everything we have learned about the Universe comes from studying the light or electromagnetic radiation emitted by objects in space. To get a complete picture of the Universe, we need to see it in all of its light, at all wavelengths. This is why it is so important to send observatories into space, to get above our atmosphere which prevents so much of this valuable information from reaching us. Since most infrared light is blocked by our atmosphere, infrared astronomers have placed instruments onboard, rockets, balloons, aircraft and space telescopes to view regions of the infrared which are not detectable from the ground. As a result, amazing discoveries about our Universe have been made and hundreds of thousands of new astronomical sources have been detected for the first time. Due to the rapid development of better infrared detectors and the ability to place telescopes in space, the future is extremely bright for infrared astronomy. Ground based infrared observatories, using advanced techniques such as Adaptive Optics are providing fascinating views of the infrared Universe viewed through our atmosphere's infrared windows. Mauna Kea Observatories Although these observatories cannot view at other infrared wavelengths, they can observe the near-infrared sky almost anytime the weather permits, providing valuable long term studies of objects in space. New missions are being planned to get above the atmosphere to observe the infrared Universe with better resolution than ever before.
