How to Take a Star Photo and Star Wallpaper Photos
Many of us have been interested in seeing an interesting and beautiful sky photo taken at night. Anyone who has a camera wants to take such a photograph. Let's start to explain.
The most difficult part of the question is how to take a night sky photo or take a photo of the stars. Even if we try to focus such a shot, the camera will try to focus continuously, but in the end we won't find the focus point or sharpen in some way. The only reason for this is that there is no light and no contrast necessary for focusing in the night.
- Take a Star Photo Environment:
City lights reflected in the night sky in the city is a major obstacle to taking photos of the sky. First of all, we have to go outside the city and go to a place without quite a light. Again, because of this reason, the location of the car should be away from the headlight lights. A vehicle passing the headlights on at the time of the shooting, all our efforts are in vain.
For this, if we want to see many stars bright, we must be away from the thick layer of atmosphere that we are under. For this, the first way is to reach the highest possible elevation and capture the moment when it has the least moisture as much as possible. If you have noticed, the observatories are in the positions where we have the conditions mentioned above.
It is also very important in shooting time. Even though it seems to us that the sun has set, it will have an angular reflection of sunlight on the atmosefer, which will cause less stars to be visible due to the light there. For this reason, it is necessary to shoot at least 4 hours after sunset. If we think we are going to shoot in the summer, we can say that the hours between 1:00 and 4:00 are the most appropriate.
The full moon in the sky is a disadvantage in terms of star visibility, when we are shooting we will choose the days when the moon is crescent, and we will have a chance to get a better image if we shoot on the internet based on moonrise and sunset times.
- Take a Star Photo Equipment:
Stars Photo ğ shelf then shot the two most important equipment for lenses and tripods . It's important that the lens has a wide angle. 18 mm. Starting with the lenses we have almost most of us. But if possible 10-20 mm. shooting with wider angle lenses will give better results. Tripod'nun will do long exposure to shake, quality and robust structure is very important otherwise all our efforts will be wasted.
In another matter, we should bring a laptop to us if possible so that all this effort is not wasted . In the test shooting, we must quickly check that the focus is correct on the big screen, especially small objects such as stars may appear to be in focus even though they are misplaced in the small screen of our machine.

Exposure Time (Snapshot):
We connect the camera to the tripod and set it to the desired sky position and bring the shooting position to manual mode. The exposure times for 10-15 seconds and 20 seconds are enough time for shooting. Longer periods can be seen in a nice photo, causing the moving track of the stars to appear because of the rotation movement of the world.
Nowadays, the entry level DSLR machines, as of the writing date of the article , provide an average of 800-1600 ISO values which provide clean photos for these shots . In long exposures, it is appropriate that the ISO value is one step above the value of our camera which gives a clean image in normal shooting, but it is still useful to find these values by testing. In general, high iso values will cause star-like sandblasting in photographs, while lower ISO values will cause fewer stars to appear.
During filming NR (noise reduction) that the blasting open reduction function ( On ) or off ( Off ), not your expectations and your choice according to the settings you choose. NR (noise reduction) open the noise to bring becomes less visible you will get a clear picture, but during the time of shooting the photo NR (noise reduction) for to continue the process, NR (noise reduction) while reducing sharpness to process noise will reduce as you get a little.
It is important to use the clearest possible diaphragm in terms of light reception. For this reason, my personal opinions and experiences with f: 2.8 value 11-16mm or wide angle lenses at these values is the most suitable for this type of photos. Lenses starting with 18mm will give us the maximum value of f: 3.5 .
Take a Star Photo Focus:
This is the most difficult part of our machine, we definitely forget autofocus. Bring your lens to manual focus, open it in live view and press ( + ) to find a bright star and magnify the image on the screen, manually scroll through the screen. After a few attempts, we can make long exposure when we find the right focus.
In some key sources, it is said that bringing the focus ring to infinity is sufficient for very long distances, but this setting method can often be misleading. Nevertheless, you can rely on the images you get from Live view to rely on your eyes.
Taking Photos as Raw : Taking pictures in Raw format is another important issue. In most parts of the frame, the information contained in the photographs in which a black image is formed is also so low. As an example, the same day it will also be set up with a JPEG photo format at 7-8 Mb while shooting at night, while the size of this value is 1-2 Mb in advance and even in some cases these Kb may fall to the level. For this reason, we must make our night shots as Raw + Jpeg . In this way, we can get a cleaner black background, much brighter stars, and also sharper pictures when we process photos on our computer.
The first thing that comes to our mind for shooting is to draw a sky vertically but it is usually our frame; forest, a hut, rocks, valley, etc. Placing objects like that allows us to achieve much more beautiful results. If you are going to draw the sky in Ille, the Milky Way is the point where we can reach the best result. Because the most star of the Milky Way will see the frame. In the meantime, if there is a car or shed in our framing, you can be sure that shining a flashlight with these objects will give great results during shooting.
- Take a Star Photo Last
but not least : We are going to go to a secluded place outside of the city. It is important to have a friend with us, if possible, and also take into account other risks that will not come to mind, and discover the possible risks to discover the place we will shoot in the daytime.
Star Exposure / How to Get a Star Photo?
It's always interesting to see things we can't see in the photo , see things slow down and make long exposures. One of these different photo types is star exposure . How are the stars exposed? Star exposure is one of the most interesting photography techniques among the beginners. It is not as difficult as it is thought to actually conceal the traces of stars .
Before the bride goes to star exposure, let's look at the equipment we need and the impact of environmental conditions. Let's start with a solid tripod that wo n't shake in the wind . Because the slightest movement of our machine causes us to lose the sharpness in our photo, and to obtain a photo. That's why a solid tripod is at the top of our needs. I got the net star photos using Manfrotto's 055XProb + 494RC2 header model. It would be easier for our lens to have a wide angle lens (18 to 55 olm for the start). A compatible control to the machine during shooting again is also taking its place among the equipment we need. If we give a little detail, we may need a compass to find the direction of the polar star .
If we take the area to be shot, there should be no light pollution . Therefore, a location away from the settlements should be selected and this should be checked in daylight before the shooting. Even a street lamp nearby, or any light source, may cause a distortion of our photo.
Looking at the lunar calendar, we must choose a time period where the moon is not visible in the sky. The exposure of the moon in the sky prevents our exposure time to be low, the less exposure time, the avoidance of the stars we want. We have to make sure that the sky is clear and cloudless. Even if the weather is a bit cloudy, it is a sign that the circular star streaks will be formed. Selecting periods in which the weather is hot to photograph stars causes our machine to become more warm. This can damage our camera, especially its sensor.
How Should Our Shooting Settings Be?
We place our tripod and machine in the area we have already determined. We start by bringing the shooting mode from the dial of the machine to the çekim manual ran . We then proceed by setting the ediy ISO ayar setting to the lowest value (eg 100iso). Because we do not need high iso values because of our long exposure, we do not want to increase this grain further, since we will get a highly grainy photo. Our snapshot setting is ane bulbWe change the value to unut and forget the control mode of the machine. Here, instead of pressing the shutter button, shooting with the controller eliminates the risk of flickering and framing of the camera during shutter release. It is also preferred to remove the mirror lock to avoid vibrations. In addition, when the shutter speed is in the bulb mode, if we do not have the control, it means that the remaining time is equal to the required value. Our snapshot can be in 45 minutes, 1 hour exposure depending on the time we prefer in bulb mode. It is usually 45 minutes, except for machines with full frame sensor, which is quite sufficient for the sensor to warm up. And by doing everything right, it will enable us to obtain the desired square.
The aperture setting should be as clear as possible. Ideal values are 4 to 5.6, but you can also make changes to the brightness of the stars according to the brightness of the stars. You can use the metering mode as the metering mode . " Long exposure troubleshooting grain " setting to bring the closed position will be useful to extend the recording time of our photo.
One of the most important parts in the shooting settings is the ability to focus. If your lens has an infinity sign on the focus ring, your job is easy, but if you have a kit lens like 18 -55 , you have to do this manually by zooming into a light (a flashlight) a few meters away from yourself. Then adjust the frame by zooming without distortion .
Now everything is ok, to determine the remaining frame and press the button of our control. Whether the polar star on the ceiling of our world in full confrontation with clear and precise circular star traces, or an object (house, tree, car, club, etc.) by taking a different photo, if we want our frames without the polar star in the non-circular star traces can be included. If we place an object in the frame, we have to illuminate the object with an external flash so that that part of the photo is not under-exposed, dark. If you don't have a flash, you can also make successful frames using the light painting technique.
Finally, if you do not want to wait for up to 45 minutes of exposure for a single frame, you can have the same photo with a shutter speed of 30 seconds, in the same aperture range, and by taking iso up to 1600 or 3200, and taking about 100 or more pictures. Although I don't support this technique much, it won't be a problem for your machine. You must always shoot in RAW format without forgetting.
It is not enough to press the shutter button to take star pictures with the DSLR camera . A few tips to photograph the stars in the sky will make your work easier.
Choosing Time and Place for Take a Star Photo
A dark space is needed to capture a beautiful star photo . For this to be outside the city as well as the Full Moon does not make your job easier. When you go out to your apartment's balcony you'll see a lot of stars outdoors, when you go away from the city lights, you'll see the number of stars and brightness in the sky. The biggest proof of this is that when people looked at the sky when the earthquake ceased, people tried to connect it to a supernatural event.
In fact, when we look at the sky in a dark darkness, there are 320 billion stars in our galaxy, but we can see only 4,000 of them. But be sure to take a picture of more stars than the human eye can see with the right DSLR camera settings.
Correct Equipment for Take a Star Photo
After finding a dark space without a full moon, the camera came to the camera. It is an ideal choice for photographing wide-angle lens stars , especially indispensable for space photographers . If your budget is appropriate, take a wide-angle aperture open wide angle lens . As the biggest secret of the star photographs, long exposure is required, I recommend taking a solid tripod that will not waste your effort . The tripot you take should be easily rotated to the sky and not affected by the wind. It may be impossible to turn some tripods into the sky or to certain angles.
In a photographer's bag going to take a photo at night ; no need to have flash for external flash, compass, backup memory card, backup battery and composition. Especially, keep the flashlight with you as a complementary element.
Polar Star
If you look at the star photos on the Internet, all the stars are in action, the only constant star that draws a trace is the Polar Star . The reason for this is that the Pole Star is the same as the axis of the world and never replaces it. Before the compass was discovered, the sailors would find their way with the help of stars, and the star of the most important direction was the Polar Star. Don't think the other stars are moving. In long exposure, the main reason the stars move is the rotation of the earth around its axis.
In order to take the Polar Star to the center and shoot the stars , with the help of a compass, find the pole star and set up the tripod and turn the camera towards the Polar Star. Pull the ISO value as high as possible and take a short 15-30 second shot. Look at the photo you're taking and adjust the frame of your second photo better and shoot with long exposure.
I recommend that you turn the camera off if the NR feature is on, because if the NR feature is on, the camera will send the memory card to the memory card by limiting the picture to the memory card when the picture is taken. If you can't see the image immediately on the screen after the long exposure is finished, your NR is highly likely.
Shooting Adjustment
Now let's make a nice setting and take a picture. We reduce the ISO settings. We set the shutter speed to ve B: - Bulb mode, F: 2.8, F: 3.5 and F: 4 are enough for aperture adjustment. Do not forget to pull on RAW. White balance gi Tungsten ra, the AUTO white balance is close to the daylight value so that the image comes in orange. After turning off all the lights on your side, press the shutter button.

Tips for taking a star photo!
Professional shooting techniques “Food photo Profesyonel
Photographing the sky and stars with your DSLR camera is easy when you take a look at a few points Dol According to Canon, it is possible to photograph billions of stars including a suitable lens and floating stars in a dark environment without a Full Moon!
When we look at the sky at night we see many stars. The number of stars you can see even with the naked eye is about 4 thousand, away from the city lights and in a dark place. However, there are about 320 billion stars in our galaxy. The closest star to the Earth is the Sun, which is 150 million km away and reaches the light in 8 minutes. The Polar Star, which is 2450 times larger than the Sun, is 430 light years away. And these stars are photographed and photographed with huge telescopes, and you can photograph them with a DSLR camera that you can use easily.
As you can see the stars in the sky motionless as you see it, you can also make the stars look like they are turning in the sky due to the long movement of the Earth around its axis and the movement around the sun.
1 - Dark space is enough
The most important point of taking a star photo is finding a good place. The darker the space to be shot, the greater the number of stars that can be photographed. Usually away from the city lights, deserted and preferred to shoot in the nature before the shooting day before the weather is always light, both security and the observation should be made for the observation.
2 - Watch the full moon!
After finding the shooting place, you will be healthy to determine the shooting date according to the status of ”Moon Çekim. You can choose the moon when the moon was never born, sank in the early hours or was born late. Because especially when the moonlight illuminates the sky in full moon time, the stars will be hard to see and the exposure time will decrease considerably. In addition, cloudless weather should be preferred.
3 - Wide-angle lens indispensable
After selecting the venue and selecting the shooting day, the order is coming to equipment preparation. Wide-angle lenses, which are indispensable for landscape photography, are also indispensable equipment for photographing stars. Especially those with an open diaphragm bir You may need a solid foot that will respond to the pressure of the machine and the lens for a few minutes, and that will not be affected by the wind, as the exposure times will be longer. And you need to take your cable shutter or remote control to start and finish our exposure.
In addition, there must be a flashlight or headlight in your bag. You may need a spare battery, a spare memory card, a compass, or even an external flash between the equipment you take with you.
4 - Shooting the Polar Star
It is often the most preferred in star trail exposures to attract the rotation of other stars around the Polar Star. Since the Polar Star is almost in the same direction as the earth's axis, it does not move throughout the day and always shows north. Other stars are also fixed in the sky. As the Earth rotates around its axis and moves around the sun, the stars appear to be turning in the sky. The extension of the Earth's axis of rotation in the north, that is, the hemisphere in which we are, passes through the Polar Star; only the Polar Star in the sky is fixed. We can see from the half sphere that we are rotating by drawing circles around the Polar Star of other stars.
After finding the pole star with the help of a compass, you can open the three feet at low level, then rotate the lens of the machine you put on, you can manually adjust the lens to endless focus.
Before you start shooting long exposure, you can increase the ISO value for both sharpness and framing control and take a short 20-30 second shot. You can review the image in detail on the LCD screen and pass the long exposure after that.
This short exposure is another feature other than the framing control. If you cannot see the image on the LCD monitor at the end of the 20 second exposure and exposure, your machine's üy Noise Reduction b (NR) feature is turned on. The NR feature reduces the noise in the picture and writes it to the memory card. Therefore, it is almost a waste of time because cleaning is done until the shooting time. Therefore, you should disable all features such as leri High ISo Speed Noise Reduction D, ”Long Exposure Noise Reduction“ and ”Active D-Lightning ın.
If your framing is smooth and clear, all the features of your machine are closed, if the tripod is firmly pressed, you can start shooting by checking the machine for the last time and turning off your lanterns. First of all, you need to drop the ISO again. In the alı B ver -Bulb mode, the aperture setting should be the most open F value in the lens setting. F / 2.8, F / 3.5 and F / 4 will be sufficient. Although you will always have the RAW format, it is recommended that you set the white balance to ıza Tungsten Fotoğraf. The AUTO white balance causes the sky to appear close to orange, giving Kelvin values close to daylight. After you have set the remote control to the shooting setting, all we have to do is press the button of the remote control by turning off all your light sources.
Probably the best thing is to rotate the stars around the pole star, but it's also possible to get different images with different frameworks. For example, you can get a very different image if you rotate the frame you're shooting by 180 degrees to the opposite side. Because there is no southern star, the stars turning right with the Pole Star turning to the right and the stars turning to the left intersect with each other in the opposite direction.
What should you do if you want to photograph the image or even the Milky Way after viewing the star marks with a long exposure? The equipment you can use for this is also very convenient. and the 2.8 aperture lenses are ideal for viewing the Milky Way. If you are using a lens with 4 apertures, you should keep exposure longer. The disadvantage of keeping long is that the stars are transformed into a comma view rather than a point. That's why the number 500 is divided into mm of the lens you are shooting, and shooting for about two seconds is ideal for photographing stars like dots. Instead of the low iso you can use for star traces, this time you should use a high ISO. According to the light pollution around 800 and above ISO can prefer.
6 - What is toast technique?
You may not always find the pitch that you want, you may not be able to extend the star marks. In these cases, you can use the Toast Technique. This technique is created by overlapping the photos taken with the editing program. As you take a Milky Way photo using the Time lapse control, 30-second pictures are taken with no aperture and high ISO (usually 400 and 800) without interruption. You can use the free edit programs that you can easily find from the internet to combine.
What most of us see and wish for is a star-shift; In fact, the length is actually about 1 mm in length of comet dust from the ground 80 km above the ground in contact with the air flashes. On rare occasions, however, the remains of comets pass very close to the Earth. Perseid, Leonid, Geminid meteor showers are among the most famous. It is possible to watch almost 100 meteors per hour in the Perseid meteor shower which is the busiest in August 12-13. Since their lights are very small, it is not possible for them all to be photographed.
For meteor shots, you can learn the direction of meteorites and use the toast technique by turning the frame in that direction. Thanks to the high iso, it is easier to capture the meteorites that are less light and then you can combine all the photos to create a star trail.
