How to focus on the starry sky with SLR?

How to shoot the starry sky with a SLR camera

I am very responsible to tell you that AF is absolutely not allowed when shooting the starry sky, only MF must be used. When shooting the starry sky, the shutter speed should not be slower than 1 s, otherwise it will cause obvious star orbit. Therefore, we must use high ISO to shoot the starry sky, and the aperture should be as large as possible, preferably fixed focus (full opening will not be too fleshy, and the amount of light will be sufficient). When MF is in focus, the starry sky must be slightly out of focus, right! You can't let the lens focus at infinity, or the stars will make the sky full of noise. Think for yourself. A tripod is a must. Color temperature? Adjust at will. In any case, you must use the original output and process it later. There is no fixed standard until the color temperature is adjusted to satisfaction.

The starry sky portrait must use an external flash to fill the light, and cannot flash directly. Soft box or reflective umbrella must be equipped.

How to shoot the starry sky with a SLR, what problems should I pay attention to?

Extend the exposure time of the camera as long as possible.

We all know that the speed of light is fast, but it takes time to travel. Some star galaxies are very far away from our earth, and their light will take a long time to spread to the earth. Therefore, extending the exposure time can make the camera capture more light and shoot bright stars.

For example:

Shooting the starry sky in a big city, even if you can't see a star with the naked eye, you can shoot at least dozens of stars after more than one minute of exposure. And you can capture an amazing number of stars by time exposure shooting at the top of the mountain in the wild.

In addition, if you want a more beautiful effect, you can also superimpose your own photos, and the effect will be dazzling by 0.0~

How to shoot the starry sky with SLR

1, tripod iso 100 with stable shooting starry sky trajectory, manually focus to infinite aperture 8 or 1 1 (many lenses 8 are the best aperture). The shutter starts at 10 second, and the test of 15 20 becomes slower and slower until you take a photo that you agree with. 2, pure shot starry sky stable tripod iso 1600 or below (1600 or above, the noise is obvious, especially Nikon, the noise is more than Canon) Aperture 8 or 1 1 Adjust the shutter to shoot more according to the values in the frame, compare the best shutter, and then start creating.

How to set up a SLR camera to shoot the starry sky? The venue is on the mountain.

1. camera settings: put the camera firmly on the tripod, plug in the cable releaser, and adjust the camera to the position of door B. If the camera has the function of lifting the mirror in advance, we will try to open it. Regarding the use of B-door and the use of reflector pre-elevation, the operation of different brands of cameras is slightly different. Please refer to the camera manual.

2. Lens setting: If it is a digital SLR camera, adjust our autofocus lens to the M position, that is, the manual focus position, and screw the focus ring to infinity. Most of the lenses of film cameras are manually focused, and the focus ring is directly adjusted to infinity.

3. Foreground application: When shooting starry sky works, never look for some prospects in the picture. A tree, a temple, a road on the ground, etc. Can be a bright future. It's not nice to shoot the starry sky alone, even if there is a little prospect, it will make the picture perfect.

4. Use of fill light: Some foreground remains dead and black after long exposure. When the photographer is not showing the silhouette effect, he can fill the foreground picture with a high-light flashlight and car headlights for one or two minutes before the end of the exposure, which can make the foreground picture more layered.

5. Parameter settings: ISO 100- 10000, aperture 1.4 to aperture 5.6, shutter from tens of seconds to two hours.

6. Detailed explanation of parameters: Maybe you don't quite understand the above parameters, so I will focus on explaining why the above parameters are used.

Iso: The low iso of starry sky shooting is prepared to increase exposure time, make the picture delicate and reduce noise. Long exposure will lengthen the trajectory of stars and form circles and semicircles, while high iso is prepared to reduce exposure time. In the case of shooting stars, you should use high iso to reduce the exposure time, so that the stars will not pull out of the track. Some people think that high iso will make the picture noisy. In fact, when your machine is not very old, the picture noise is completely acceptable.

Aperture: Isn't it necessary to shoot the scenery with a small aperture? Why use such a large aperture as 1.4-5.6? In starry sky shooting, in fact, the aperture does not control blur and depth of field, because we have set it to infinite focus, and the depth of field is already very deep. The main function of the aperture here is to control the thickness of the star trajectory. The larger the aperture, the thicker the trajectory of the stretched star we see. If the aperture is small, not only the exposure time is long, but also the lines of the star trajectory will be very thin, so that the picture is not shocking.

Shutter speed: the long shutter speed is the star orbit of the circle, and the short shutter speed is the star. How to show these effects is shown in the picture through the combination of shutter speed, aperture and iso.

Tripod essential

The data in the book are: aperture coefficient of clear night sky 1 1, 1 ~ 10 second, ISO 100.

Personally, I think we can try door B, with a larger aperture coefficient.

In composition, I have read a good one. Take the silhouette effect of the mountain and highlight the beauty of the night sky under the starry sky with the ups and downs (or precipitous) of the mountain (but it is best not to have clouds). If this is the case, the metering point should be aimed at the night sky (because it is necessary to ensure the brightness of the night sky and the silhouette effect of the pure black mountains)

The other is my own idea, shooting the sky through the branches in the Woods. You can choose a place where the branches form a frame around the photo to cover the sky, and the whole night sky is exposed in the middle. In this case, the branch needs to be considered in the metering, and the branch needs to show its proper outline. If there is enough light, the branches can be photographed more clearly. This kind is best in autumn, after some leaves fall. Otherwise, too many leaves may completely cover the night sky.

Nikon's D200 effect can definitely take good photos.

A few digressions: I've always wanted to shoot the starry sky, but living in the city, I can't see the magnificent starry sky at all. Rogue ~ ~ if you can really shoot, send it up. Let me see. Please.

If you can't answer the question, you can ask it in the shadow, where there are more experts. (individual)

Entry SLR can shoot starry sky

In fact, shooting the starry sky does not require many high-end machines, and the low-end entry-level SLR can meet it.

Generally speaking, it is easier to show charm with a wide-angle lens when shooting stars.

Because it is shot at night, the light is very dark and the exposure time is long, so you must have a tripod.

Pay attention to stay away from the city lights and avoid light pollution when shooting, so as to shoot a clean starry sky.

Use small aperture, manually focus to infinity, use tripod and cable to release, and use exposure delay if necessary. .

Since it is new to you, there is no need to get a good shot. It's best to wait until you know your needs before buying a better lens. Now buy a machine directly and practice your hands first.

If it is a low-end model, Nikon d3200+ 18- 105, D5100+18 =105, Canon 600d+18-/kloc-.

If you want a better fuselage, you can buy Nikon d7000+ 18- 105 and Canon 60d+ 18- 135.

What if I can't focus on the starry sky at night? Ask the great god for guidance!

Infinite distance is enough. Use your hands.

How does Canon 760d shoot the starry sky? Why can't it focus?

First of all, you should prepare a tripod and wire control. Shoot on a clear night. It's best to adjust the aperture of the lens to the maximum to let more visible light in. It is not easy to focus at night, so focus manually with MF on the lens. I have an experience, generally manual diagonal, turn to the end, and then a little later, you can get it. Shutters usually take a long time. It is recommended to be around 8 seconds. Don't drive for 30 seconds, or longer, it will make the track of the stars look like a star track.

When shooting the starry sky with a SLR, does the lens have to be screwed to infinity? But there is no sign of infinity on my lens.

No, telephoto end or wide-angle end will do. Use tripod, high ISO, long exposure.

How to set the focal length to infinity when shooting starry sky?

What did you shoot with? If it is a SLR camera, there is an infinite mark on the lens. Just twist it to that marked position, turn it a little to the left, or focus on the brightest star, depending on the performance of your lens.
