A tripod is necessary, because the sky was dark when the total solar eclipse occurred, almost like a moonlit night! Because of the rotation of the earth, the sun is always moving when shooting, so it is best to use a gear pan/tilt. To take one or two photos, you need to adjust the tripod head and put the sun in the center of your field of vision. If you have a gear tripod, you can configure an equatorial tripod, that is, the angle between the central axis and the ground is equal to the local latitude, and the central axis faces north. In this way, you can track the sun by turning a knob.
During the partial solar eclipse, never use the lens to direct the sun. You need to cover the lens with a dimming film to reduce the light entering. In recent years, Budd membrane is easy to buy. It is cheap, easy to use and has a good effect. There are two densities of Bard film on the market, which can be shot at a density of 3.8 and observed at a density of 5.0.
Exposure rate:
The exposure of different subjects is different, and the height of the sun and the transparency of the atmosphere will affect the exposure. Here is a total solar eclipse exposure meter for your reference. When shooting, you should look at the histogram of the shot photos and decide how to adjust the exposure.
Following the joy brought by the Olympic total solar eclipse on August 1 day last year, this month, that is, on July 22nd, China will usher in another grand astronomical landscape. The once-in-a-century total solar eclipse can be seen in China, and China will become the host country of the longest total solar eclipse in 2 132 years. I want to see the total solar eclipse again in China, and I won't see it again until 2035. The once-in-a-lifetime astronomical landscape not only excites astronomy enthusiasts, but also makes curious people pay attention to this phenomenon, so it is inevitable to shoot the solar eclipse.
However, shooting a solar eclipse is very different from shooting a general landscape photo. We need to make great efforts in shooting skills and preparation in the early stage of shooting, and we don't want to miss the once-in-a-century eclipse landscape shooting. In addition to preparing shooting equipment and appliances a few days before the eclipse, taking protective measures and understanding the principle of the eclipse phenomenon will help us better find the shooting time and leave the most wonderful moment. Next, talk about the principle of solar eclipse, and comprehensively talk about various precautions and shooting techniques for shooting solar eclipse.

Shooting an eclipse requires calculating the shooting time. The total solar eclipse belt of this total solar eclipse passes through most urban areas of the Yangtze River Basin in China, and the occurrence time of total solar eclipse in major cities is shown in the table above.
Every time there is a solar eclipse, it always attracts countless movie friends to take pictures. Judging from the works of netizens over the years, all forms of total solar eclipse are recorded, and the equipment is not important. With a little patience, it will surely take a good photo of the total solar eclipse. The longest total solar eclipse in thousands of years will happen tomorrow. I believe there will be more and better works in front of you.
Introduction of solar eclipse principle
Today, the solar eclipse is a well-known astronomical landscape. However, in ancient times, this was an ominous omen. I believe many friends still don't know much about the principle of solar eclipse. For watching or photographing solar eclipse, understanding the principle of solar eclipse is helpful to better grasp the observation time. Before we start our photography skills of solar eclipse, let's briefly explain the principle of solar eclipse.
Eclipse diagram
Eclipse means that the moon revolves around the earth and moves between the sun and the earth. If the sun, the moon and the earth are in a straight line, then the moon blocks the sunlight that hits the earth, and the shadow behind the moon just falls on the earth. At this time, an eclipse will occur. The sun is covered by a circular shadow. When it gets dark, the brightest stars and planets can be seen in the sky. After a few minutes, the sun gradually appeared from the edge of the shadow of the moon, and the light and the last contact began to appear. Because the moon is smaller than the earth, only people in the shadow of the moon can see the solar eclipse.
Total lunar eclipse occurs when the moon blocks all the sun, partial solar eclipse occurs when the moon blocks part of the sun, and annular solar eclipse occurs when the moon blocks the central part of the sun. The duration of the total solar eclipse shall not exceed 7 minutes 3 1 sec. The longest time of annular eclipse is 12 minutes and 24 seconds. China has the oldest solar eclipse record in the world, and there have been exact solar eclipse records for over 0/000 years BC.
Introduction of domestic attractions of total solar eclipse on July 22
As a once-in-a-century total solar eclipse in China, it is particularly important to know the time and place of viewing in advance. Although the total solar eclipse can be seen in most parts of China, the area where the total solar eclipse can be seen is mainly in the Yangtze River basin. The total lunar eclipse zone is relatively wide, with a length of over 65438+100000 km and a width of 250 km. Over 40 cities including Chengdu, Chongqing, Wuhan, Hefei, Hangzhou, Shanghai and Nanjing can watch the total solar eclipse after passing through the densely populated Yangtze River valley in China. The public in other parts of China can also see the partial solar eclipse.

This total solar eclipse is the longest in more than 2000 years. It takes more than two hours from the initial loss to the last contact, and the longest total solar eclipse in China can last for six minutes, which is very rare. The total solar eclipse lasted more than two hours. From 8: 00 am on July 22nd, 1 1, friends in China can watch the solar eclipse one after another, from the initial loss to the two-hour recovery.

Eye protection points of diet on viewing day
The intensity of sunlight is much higher than that of common illuminators, so eye protection must be done during the solar eclipse, and special protective glasses are essential when watching the sun. High-intensity sunlight is absolutely not allowed to be watched directly with the naked eye. Watching the sun for a long time may damage the cornea. You can't watch it with sunglasses. Ordinary sunglasses are only used for shading, and they can't resist the direct sunlight. Therefore, watching the solar eclipse still needs various direct and indirect methods to deal with it.
Eclipse observation glasses
The easiest way to watch the eclipse is to buy goggles. Related products can be clicked: goggles for watching solar eclipse. Of course, if you think this method is expensive, you can also watch the solar eclipse indirectly with the ink basin method. Pour the ink into the basin and watch the solar eclipse through the reflected reflection. Of course, this method will still feel that the intensity of sunlight is a bit high. For more novel ways to watch the solar eclipse, you can click here: skills to watch the solar eclipse. No matter what method you use, protecting your eyes is the most important.
Equipment preparation for shooting solar eclipse
Shooting a solar eclipse is not much better than taking ordinary landscape photos. Because of the strong sunlight, ordinary photographic equipment cannot avoid the tragic experience of overexposure, so some special auxiliary equipment has to be used when shooting the solar eclipse. On the contrary, the requirements for cameras are not very high. Both SLR and consumer cameras can record solar eclipses.
Solar filter is the most critical auxiliary tool for shooting solar eclipse. Budd film is the most commonly used solar eclipse shooting filter, which can reduce exposure by 10 thousand times. Through Bader film, the sun's rays are greatly weakened, making the sun reveal its original color: neutral white. Filtering out infrared rays also makes it safer to observe the sun with the naked eye.
Commonly used solar filter: Bader membrane
Because Budd film is the most commonly used solar filter for observing solar phenomena, the chances of buying fake and inferior products are greatly increased. Fake Budd film can't achieve the desired effect, and more importantly, it may damage both eyes and lead to blindness, so it must be identified when buying.
Key points of authenticity identification of Budd's films;
1, directly facing strong light (sunshine is the best), fake and inferior Budd films generally have many scratches or film perforations.
2. The genuine Bader film is made of ultra-thin aluminum film, with strong metallic foil texture and thicker inferior aluminum film.
3. The domestic price of 120 can buy A4-sized genuine Bader film. If it is significantly lower than this price, it can be considered as a fake.
As for shooting equipment, with the help of solar filters, the requirements for cameras are greatly reduced, and all kinds of shooting equipment can be used. Digital SLR cameras, consumer digital cameras and film cameras can all complete the shooting work. It is best to shoot close-ups with a telephoto camera, which can reach a focal length of more than 500 mm. If you want to record the whole process of solar eclipse, you can use wide angle for multiple exposures, which requires the support of a digital camera with multiple exposures. Using a film camera, it is easier to take photos of this eclipse. You also need to use a tripod to stabilize the camera.

Shooting skills of total solar eclipse
After the equipment for shooting the total solar eclipse is ready, several preparatory work should be done. On the day before the eclipse, you should choose the place to shoot the eclipse. Of course, the equipment should be set in advance, the camera battery should be fully charged, the memory card should be emptied in advance, and the focal length should be fixed before shooting. This requires the accumulation of usual experience, and it is necessary to repeatedly and patiently adjust the focal length to the best. If there are sunspots on the sun, we can focus on the edge of sun gear, if we can't observe them.
Set up the equipment in advance before shooting the eclipse.
There are several themes in the shooting of the solar eclipse. If you only have a wide-angle lens, you might as well shoot a group of total solar eclipse Sugar-Coated Berry, which requires multiple exposure cameras. If you shoot with a digital camera, you can also use post-synthesis. The key point is to fix the camera position by interval exposure. During the period from the initial loss to the last contact of the total solar eclipse, it is necessary to use the solar filter to control the exposure, while during the total solar eclipse, it is necessary to remove the filter to complete the exposure.
The total solar eclipse can be filmed in many stages, and the classic one is to capture Bailey beads. At the beginning or end of the total solar eclipse, sunlight is transmitted from the gap in the mountains on the edge of the moon. When the narrow crescent-shaped light edge passes through the rough valley on the moon, the sun shines through the gap on the surface of the moon and becomes a string of small beads. These light spots are called "Bailey beads". Bailey beads attract people's attention because they are dazzling and short-lived. But this phenomenon only lasts for a second or two, so catching Bailey beads is the most challenging one in the total solar eclipse shooting. When taking a snapshot, be careful not to forget to take off the sun filter. At this time, the sun has been blocked by the moon, so there is no need to use a filter to reduce exposure.
Except for the sun, a special protagonist who needs special treatment, other shooting techniques are like landscape photography, and it is most important to wait patiently for the most beautiful moment.

Exposure skills of solar eclipse photos
In addition to full preparation, we should also pay attention to exposure when shooting the eclipse. Because the shooting equipment you use is different, and the dimming efficiency of solar filters is different, there is naturally no uniform standard. Before the official shooting, it is necessary to adjust the shooting to obtain the appropriate exposure parameters. Digital cameras have obvious advantages in this respect. For users of film cameras, they need more experience, and they can also be debugged through the exposure reference table provided by us. Exposure value of solar eclipse photography can refer to: exposure meter of solar eclipse photography.
Total solar eclipse corona
Because this is a total solar eclipse, the exposure parameters can be adjusted according to different shooting contents. At the same time, remember that when a total solar eclipse occurs, the sun's rays will be blocked by the moon, so you can shoot directly without using a solar filter. To capture Bailey beads quickly, it is best to use continuous shooting, and the exposure can be increased appropriately; Chromosphere exposure time should be fast; And shooting the corona from fast to slow is1/more than 8000 seconds-1 second.
There are different exposure requirements for shooting various solar eclipse landscapes. As long as you try several times before the eclipse and adjust the exposure value, you can usually take satisfactory photos.
abstract
There is a rare opportunity for celestial photography. I believe that the longest total solar eclipse in a thousand years will make the national film photographers excited, and it is inevitable to shoot a total solar eclipse. As a special landscape photo, we need more preparation, more patience and more exposure experience. In this paper, the related skills of solar eclipse shooting are explained in detail, which is believed to be helpful to the cinematographer's desire to shoot solar eclipse. I also hope that tomorrow's total solar eclipse will satisfy everyone's curiosity about the astronomical landscape and leave a wonderful moment that has never happened in a hundred years.
