The most anticipated solar eclipse in 2020 is here. Please keep this shooting guide!
June 21, 2020, the summer solstice, the most important celestial phenomenon of the year: the solar ring eclipse will hit. This annular solar eclipse started in Africa, passed through the Middle East, South Asia, and entered our country. In our country, it will pass through Tibet, Sichuan, Guizhou, Hunan, Jiangxi, Fujian and Taiwan.
This annular solar eclipse is the only one in China in the next 10 years. If you miss it, you will have to wait until June 2030, so the opportunity is not to be missed.
An annular solar eclipse can be seen in the area within the red line, while partial eclipses of varying degrees can be seen in other areas. Solar eclipses are generally divided into three time points: first loss, eclipse and return. The first loss is when the solar eclipse has just started, the eclipse is even the sun’s shadow reaches its maximum, and the principle of recovery is the complete end of the solar eclipse. Due to the rotation of the earth, the eclipse time corresponding to different regions is also different.
is such a rare celestial phenomenon, what is a good way to photograph it? What are the precautions? What kind of equipment should I prepare? Master the following tips, and you will surely be able to take photos of the solar eclipse that satisfy you.
[choice of shooting equipment]
1. Dimming filter
Except during the short period of sunrise and sunset, in most cases, it is not suitable for people to observe and photograph the sun directly with the naked eye or camera. We need to use a filter called “Bad Film”, which can effectively reduce light, making it possible to shoot solar eclipses.
In addition to the “Bad film”, chrome-plated glass or the ND100000 light reduction filter is also a good choice. Both filters need to be placed on the front of the lens. The use of sunglasses and low power reduction mirrors can not effectively reduce light.
Special attention is that, without any filter loaded, directly observing the sun through the telescope with the naked eye will cause blindness in both eyes. Shooting the sun directly through the telephoto lens will also burn out the camera CMOS. Therefore, everyone must not take it lightly to avoid unnecessary losses.
There are many ways to take photos of the solar eclipse, and different lenses have different shooting effects. Using a wide-angle lens, you can take a group photo of the solar eclipse and the landscape, or take the whole process of the solar eclipse, and then superimpose multiple sheets to form a solar eclipse string. In this case, Canon EF16-35mmf2.8LIIIUSM lens is a very good choice. The lens covers a wide focal length and excellent picture quality, which can be very convenient to combine with the landscape composition.
If you want to take close-ups of the solar eclipse, then you need a Canon EF100-400mmf/4.5-5.6LISIIUSM lens, which not only has a long focal length and is extremely portable. The lens is only 1,570g. As heavy as an astronomical telescope, it will be much lighter when traveling in pursuit of a solar eclipse. And its resolution and sharpness are also excellent, and it can capture the wonderful details of the solar eclipse.
When choosing a camera, we need to take into account the continuous shooting speed, pixels and image quality, because the eclipse phase of a solar eclipse is only a short period of tens of seconds, while the scene of Belle Bead is only a short Seconds.
To capture the changes of the solar eclipse every moment, we need a body with a faster continuous shooting speed. In addition, high pixels are also important. Higher pixels mean more details, and can be appropriately recomposed. EOS5DMarkIV and EOSR are good choices for shooting solar eclipses. It has both continuous shooting performance and high image quality, making it more stable and reliable when shooting such fleeting spectacles.
[Photography APP helps make shooting plans]
Use some photography apps to help us take good pictures of the solar eclipse. You can use Plaint, the Chinese version of Qiaoshe, to make plans for this eclipse.
On this software, we can see the time of each node of the solar eclipse at a specific location, the sun’s trajectory and other important information.
[How to focus on the sun]
When shooting a solar eclipse, we often encounter problems with focusing on the sun. At this time, the autofocus function often fails effect. The focus point is near infinity, but the specific location must be after the Bard film is installed, through the camera’s live view function, magnify 10 times, fine-tune the focus ring, and select the minimum and sharpest sun. This focusing method is somewhat similar to shooting the starry sky.
It is worth noting that due to temperature changes, the camera and lens are exposed to the hot sun for a long time, which will also cause the focus to shift. Therefore, before the eclipse phase, you need to focus again to ensure that the focus is accurate during the eclipse phase.
[Different angle shooting methods]
Telephoto lens shooting day Eclipse close-up
When shooting a solar eclipse close-up, we need to use the longer focal length and shorter exposure time possible. When the weather is clear, we must use the Bard film to shoot, and the shooting parameters are based on the clear and overexposed sun.

is different from the total solar eclipse, the ring eclipse In the eclipse phase, it is difficult to determine in advance whether to use the Bard film. It is affected by the sun’s altitude, eclipse and weather conditions. It is best to consider removing the Bard film when the sun is not glare to the naked eye. Otherwise, if you are not careful, the CMOS of the camera may be damaged after removing the Bard film.
It is worth noting that due to the influence of the earth’s rotation, the exposure time cannot be too long during fixed shooting, otherwise the sun’s movement will make the picture unclear. At this time, you can consider using an equatorial mount for tracking and shooting. Exposure time. In the eclipse phase, you can also adjust different exposure parameters for HDR shooting to get more details.

If the area is cloudy or cloudy , And occasionally the sun appears. When the sun is not dazzling and dim, you can also use the camera directly without using the Bard film. Because the clouds at this time have a natural light reduction effect.
Wide-angle lens to shoot the whole process of the solar eclipse Orientation for preliminary preparations, and then determine the shooting plan and composition according to the landscape.

The whole process of shooting the solar eclipse, we need to take a close look at the first loss, the beginning of the eclipse, the extreme eclipse, The time point of end and recovery of the ring eclipse. From the initial loss to the beginning of the ring eclipse, and from the end of the ring eclipse to the recovery stage, the Bard film must be used. In the eclipse phase, you can take a picture with and without the Bard film.
When shooting with a Bard film, our shooting parameters are based on the clear and unexposed sun. If the Bard film can be removed, the shooting parameters are similar to those at dusk. The time interval for taking each photo can be 30 seconds or 2 minutes. In this way, the whole process can be recorded through continuous exposure.
In post-processing, we need to select multiple photos taken at the same interval according to the composition requirements for superimposition processing. The superimposed film can use photos taken during the eclipse, and the superimposing software can use Starstax or Startrails.
3. Use a medium-focus or wide-angle lens to shoot food directly

When shooting food with a medium focal or wide-angle lens, you may be able to shoot without considering the use of Bard film To the photo of Shishi. The shooting parameters are similar to dusk, but the exposure time is as short as possible. Due to the weather, the shooting parameters are not fixed, and multiple exposures may be used to obtain higher tolerance and detail.
[Photographing a solar eclipse through the principle of small-hole imaging]
In addition to photographing the sun directly, we can also observe and photograph indirectly eclipse. For example, using the principle of small-hole imaging, prepare two pieces of white paper, one piece of white paper is put on a neat circular small hole, and the other is placed behind the small hole, so that the sunlight is projected on the paper, and the paper can be seen The crescent projected on the surface.
Observe the solar eclipse through small hole imaging
During a solar eclipse, we can also shoot in the tree-lined road, and the gaps in the shade of the trees will become natural small holes. The small bright spot under the shade of the tree is the small hole image of the sun.
[About the weather]
The last and most important factor is the weather. From the current situation, the best observation sites on the solar eclipse zone are the Ngari area in Tibet and the Litang area in Sichuan to the Qamdo area in Tibet. Although the weather is the most unpredictable, but observing the sun is not absolutely demanding on the meteorological environment. Sometimes there are thin clouds, which will add color to the photos. If the weather at the location is sunny, you can take photos of the eclipse skewers and close-ups. If the weather is cloudy, you can also take a close-up of the partial eclipse through light-transmitting clouds.
Learn the shooting skills, quickly pick up your camera, and wait for June 21st to shoot your large solar eclipse!
