How to shoot the wonderful starry sky

In our daily life, we all know some parenting knowledge more or less. Here, I have compiled some related contents about how to shoot the wonderful starry sky for you. Welcome to share, I hope it will help you.

How to shoot the wonderful starry sky

First, the preparation of equipment In addition to the camera and lens, you should bring a tripod/cable arranger/two full-power batteries/flashlights; If you can't find the stars and have a weak sense of direction, you should also bring a compass.

1. compass (compass is also acceptable): First, find the right direction and determine the shape of the star track in the composition. Facing due north, you can shoot a circular star orbit centered on Polaris; Facing the northeast or northwest, you can shoot fan-shaped star trajectories. As for why this phenomenon occurs, I won't go into details here. Please read the relevant junior high school geography textbook.

2. Tripod/cable release: The stable combination of tripod and tripod head is as important as camera and lens. If the camera moves during a long exposure, you will lose all your efforts. Cable release is mainly used to lock door B. If you don't know what door B is, or your camera doesn't have door B, please don't look down.

3. Two fully charged batteries: one for the camera and one for backup, because it takes a long time, one hour, even several hours, or until dawn to shoot the orbit of the star. You should always observe the power, and then decide your exposure time or change the battery.

4. Flashlight: On a windy and dark night, a flashlight is everything. It can help you find your way home, fill the light, focus and so on. You don't need a camera, but you must bring a flashlight.

The exposure time lasts about one hour, and a circular star orbit is obtained by using a 14mm lens, f3.2, iso 100, facing due north.

Second, choose the right weather and time to get the best image. It is the best condition to ensure the success rate of shooting to choose sunny nights around April and 28th of the lunar calendar, to go to villages and hilltops far away from the city and not see your fingers. Can I shoot at other times except the lunar calendar 1 month and March? Yes When you have considerable experience, you can use multiple exposures and hundreds or more photos to synthesize a rare work.

From night to dawn, a picture was synthesized after exposure in sections, and a picture recorded the struggle for three hours.

Third, focusing and composition 1, composition: it is not difficult to focus and composition in the dark. First, set the ISO of the camera to 6400 or even higher, then play it back with the camera display screen after shooting, check the position and layout of the scene, and adjust the composition repeatedly. After finishing the composition, you must remember to restore ISO to the normal value of 50-200.

2. Lens focusing: First of all, focus on infinity. For the use of wide-angle lens, this is a short-range and simple focusing method. In order to focus on the foreground or nearby scenery more accurately, first illuminate the focused scenery with a flashlight and complete the focusing with the brightest reference (manual is recommended).

Fourth, set up the camera and complete the long exposure shooting.

1, camera setting: First, turn off the long noise reduction setting, because the noise reduction time of the camera is as long as the exposure time. For example, the exposure time is 60 minutes, and the noise reduction time of the camera also takes 60 minutes, which takes a total of 2 hours. Generally, it is difficult to support a single battery on board. If the power is cut off in the middle, the consequences will be very serious. Don't take any risks. Let's put the noise reduction work in the later stage.

2, lens settings: use a large aperture, the thicker the star track, the thinner the star track with a small aperture, and set the aperture as large as possible; F2.8——f4 is the best, so as to ensure sufficient light and obtain significant star trails.

3. Exposure time: The longer the exposure time, the longer the trajectory. Can also be divided into several short exposure, late Zhang Hecheng. If your camera doesn't support long exposure, or you have enough post-production ability, you can try multiple exposures.

4. Multiple exposures: First of all, you need a cable releaser that can automatically control the exposure time, shooting number and shooting frequency, and set it to automatically shoot one at an interval of 1 second; Each exposure time is 2-4 minutes, and the number of shots is 30. You can also get a star track work with a total exposure time of 60 minutes. Be sure to remember that the ISO setting should be improved by 500-800, so don't say the reason, and you will know after several failures.

The length and thickness of the star orbit can be controlled by the focal length and aperture of the lens, and the fan-shaped star orbit can be obtained in the northwest and northeast directions. Use a 24 mm moving lens.

Verb (abbreviation of verb) The shooting skills of the Milky Way and Nebula have mastered the shooting of the orbit of stars. The shooting of the Milky Way Nebula is pediatrics. Having a good high-sensitivity camera is omnipotent. CANON5D2 (now 5D3 is better) is recommended.

1. Use the same equipment and accessories as shooting the orbit of stars. ISO is set to 1600-3200 or higher, and the exposure time is controlled between 50 seconds and 30 seconds. The shorter the exposure time, the clearer the nebula. Of course, your camera needs better noise control ability.

Photographing the Milky Way Nebula is the opposite of photographing the orbits of stars. High sensitivity means shortening exposure time. When the exposure time is long, there will be obvious tracks and the Milky Way will be atomized, so the shorter the exposure time, the better.

2. Shooting the Milky Way Nebula requires higher atmospheric transmittance and environmental darkness. The samples in this paper are all taken in high altitude areas or grasslands, away from light and air pollution.

Photographic skills of shooting beautiful starry sky

Step 1: Prepare

First of all, you need to find the right location under the right conditions, so as to increase the chances of taking wonderful photos. I live in a city in northern England, and I can hardly see the starry night sky. You need to go to a remote place, away from the light pollution in the city. Choosing a sunny night will also help. Check the weather forecast in advance, of course you don't want to be blocked by thick clouds.

It is very important to keep the camera completely still during a long exposure, so you must use a stable tripod. Cable release is also useful to avoid touching the camera during exposure. Any slight vibration will affect the exposure effect. When you start to press the shutter, one trick is to cover the lens with a piece of dark cardboard, and once the camera stabilizes, take it off.

Step 2: Clear the photo

Because the earth is spinning, it is difficult to take clear pictures of the starry sky unless you have professional telescopes and other equipment. The longest exposure time should be limited to about 15 seconds, without obvious tremor. In order to get a clear picture of the starry sky, you need to choose a clear night. Choose the aperture as large as possible, such as f/2.8, and set the shutter speed between 15 and 20 seconds. You also need to set the sensitivity. In order to control noise, ISO 100 or 200 is ideal. But for accurate exposure, you may need to increase the sensitivity.

Step 3: Star Orbit

The first thing to understand when shooting the starry sky is that the earth is turning, which means that the stars will move after you shoot. This is the so-called "star orbit" effect, as you can see in the chart. In order to capture the picture of the star orbit, set the aperture as large as possible, from f/ 1.8 to f/4, and set the focal length to infinity, and then aim the camera at Polaris, which will remain stationary while other stars will revolve around it.

Also, you need to set the sensitivity. Initially, the sensitivity was ISO 100. In order to increase exposure, sometimes you need to give in to noise. The exposure time varies according to the light projected by the moon. If it is a new moon, the exposure time is about 1 hour; For half a month, the exposure time is controlled at 20 minutes. This is just an attempt to use the existing light. But remember, the longer the exposure time, the longer the star track appears.

Step 4: Equipment

Remember to bring some basic items, which will make your whole shooting smoother. First of all, a flashlight will make it easier for you to set up your camera and find a flat place to put your tripod. Don't leave the shutter open when you press it. Secondly, if you shoot for a long time, bring one or two spare batteries. Third, you can use a stopwatch or timer to check the exposure time without touching the camera. Finally, if you feel tired or very tired, a chair or bench is quite useful.

Step 5: Go out to practice at night.

Shooting the stars is very tiring, especially an exposure takes a long time. However, when you take the photos you want, it is also worthwhile. You can also go out to shoot the moon at night. This is a good practice opportunity, which can help you master some basic essentials.

It is difficult to capture the pictures in the starry sky with a camera, but once you master some basic exposure setting skills, you will find it less difficult. What you need to do is to keep practicing and use composition to find the right conditions. After one or two attempts, you will take good photos.
