How did the starry sky and the Milky Way be photographed?

  We often see the gorgeous stars and galaxies in Weibo, public accounts, and posts, admiring the coquettishness of the universe. In fact, you can also take a photo of your own starry sky and galaxy, or even a starry sky and galaxy dressed up with aurora. The technique of photographing the starry sky and the Milky Way is far simpler than you think, but it requires high equipment and environment. Today, I will take you to fully understand how the starry sky and the Milky Way are taken.

How did the starry sky and the Milky Way be photographed?

The environmental conditions required for shooting are very high.

   Let’s talk about the shooting time. We shoot night scenes. The best time is the moment when the sun just sets on the horizon, and the sky is not completely dark yet. There are colors or blues. Glorious. But shooting the starry sky and the Milky Way can easily be affected by other lights. That is, it is best that the sky is completely dark, and the moon should not affect the shooting as much as possible. Generally speaking, you have to wait until midnight.

  The weather is very simple. A clear sky is the best, and an environment with few clouds is also OK. As long as the weather is cloudy, smog, rain and snow, etc., you can go home and rest.

   Next is the shooting environment. The best place to photograph the starry sky and the Milky Way is in the wilderness, which is to avoid artificial light pollution caused by cities, towns, and villages, which is to avoid the appearance of lights. So we see that domestic photographers like to go to Xinjiang, Tibet, Inner Mongolia and other places to shoot in no man’s land. Because other light sources will cover the faint starlight, the scene in the picture is not so shocking.

   Continue, prepare for shooting. The first is to use “starry sky and moon phases” apps to query the time trajectory of the moon, the position of the Milky Way, and so on. This is very important to avoid not being able to capture anything.

   Then the preparation of photographic equipment. A very stable tripod is necessary. As for how high the price can be, it is up to everyone. Cameras, SLRs, and micro-single cameras are all good. The larger the sensor’s frame, the better the effect. Generally, full frame is enough. The best combination of lens, large aperture and wide angle, such as 24mmF1.4 lens, 16mmF1.4 lens and so on.

  The sensor has a large frame. In order to better control noise when used in high-sensitivity, the wide-angle lens can shoot more stars, and the large aperture is in order to capture the faint starlight, so this combination is required.

  How to adjust the camera parameters during shooting

  The most critical step is to adjust the parameters before the shutter.

  The parameter part is nothing more than the three options of aperture, shutter, and ISO. The rest of the parameters are the same as the head-up. In addition, some operations on the lens will be clear to everyone. The camera mode is recommended to use M gear, manual gear.

   aperture, use the maximum aperture of the lens, such as F2.8, F1.8, F1.4, etc. As mentioned above, this is to make the lens perceive weaker starlight.

  Shutter, generally takes 15-20 seconds. It doesn’t take 30 seconds, because the star trails will appear after 30 seconds of exposure. Of course, if you don’t mind, 30-second exposure is also possible. If you want to take a single star track photo, you can use the B door with a shutter release to shoot for 20-30 minutes to have the effect, or stack it up. I will share this with you in a separate article.

  ISO, this is more complicated, it depends on what format camera you are using. For APS-C format, ISO 1600 or lower is recommended. If you use full frame, it is recommended to use between ISO 1600-6400. For example, 5D4 level can use ISO 1600, and 1DX level can use ISO 6400. The ISO does not have to be in this range, you can also try it yourself. The high ISO you use depends on your camera’s noise control ability. Because a long time exposure will add to the appearance of noise.

   The other is the lens. The lens needs to use manual focus mode. Generally, the focal length of the lens can be adjusted to infinity. Some lenses need to be adjusted to infinity and then screwed back a little bit, because some lenses will be out of focus at infinity.

   The next thing is to press the shutter and wait for the harvest The photo is out. It is difficult and difficult to shoot the starry sky and the Milky Way. It is not easy to say it. The important thing is to be familiar with your equipment and to understand the meaning of each parameter adjustment. In addition, it takes luck to be able to take a successful starry sky and galaxy photo.
