Советы по съёмке ночного неба








Есть в этом какая-то магия, когда ночью выезжаешь за город, и перед тобой открывается ночное небо со всем его многообразием звёзд и галактик.
В этой статье мы расскажем, как фотографировать ночное небо на смартфон с применением Galaxy S20 Ultra, чтобы сохранить волшебство в кадре.
Оснащённая сенсором 108Мп и технологией nona-binning, благодаря которой матрица получает больше света, камера на Galaxy S20 Ultra способна создавать красивые ночные фотографии.

Перед выходом из дома

Запланируйте съёмку, зная, какой объект собираетесь снимать, а также оптимальное время и место. Если вы хотите сфотографировать луну, лучше дождаться новолуния. Не забудьте взять с собой фонарик и внешний аккумулятор для смартфона.

На месте

1) Установите оборудование. Для создания качественного снимка ночного неба потребуются длительная экспозиция или низкая скорость затвора. Вам понадобится штатив и дистанционный спуск затвора или таймер, чтобы обеспечить стабильную работу камеры при съёмке на длительной экспозиции.

2) Используйте Pro Mode: автоматические настройки на вашей камере не подходят для съёмки Млечного Пути. Переключитесь в режим ручной настройки для управления ISO, выдержкой и другими параметрами, чтобы отрегулировать освещение и режим для каждого кадра.

3) Настройте выдержку: её можно использовать для получения различных стилистических результатов на фото. Например, если ваш затвор остаётся открытым достаточно долго, вы запечатлеете вращение Земли, что приведет к появлению «следов» от звёзд на изображении. Отрегулируйте скорость затвора и либо получите статические изображения ночного неба, либо используйте более длинную выдержку, чтобы передать на фото перемещение небесных тел.

4) Настройте баланс белого. Этот параметр цветовой температуры вашего изображения и используется для того, чтобы белые объекты выглядели белыми и на фотографии. Для съёмки звездного неба вам, скорее всего, понадобится баланс белого между 3500 и 4500 кельвинов.

5) Отрегулируйте ISO: ISO – это показатель светочувствительности датчика изображения. Чем выше значение ISO, тем выше чувствительность к свету, что облегчает создание ярких кадров даже ночью. Но это также может привести к зернистости или шуму на фото. Отрегулируйте ISO в зависимости от окружающей среды, чтобы снизить уровень шумов до минимума, и при этом позволить датчику собрать достаточно света для получения качественного снимка.

Как сохранять фотографии

В режиме Pro убедитесь, что снимки сохраняются в формате RAW. Вы можете активировать эту функцию в приложении «Камера», выбрав «Настройки»> «Сохранить параметры»> и нажав на «Сохранить копии в формате RAW». Файлы в этом формате лучше подходят для постобработки, чем JPG или PNG, так как сохраняют больше информации о снимке.

Capturing the Galaxy on Galaxy – Smartphone Photography that Shoots for the Moon

A night sky scattered with sparkling, gem-like stars provided the canvas for this stunning photo of the Milky Way, which is from the official Samsung UK site. Incredibly, this photo took neither specialized equipment nor a professional photographer to shoot, but only required the Samsung Galaxy S20 Ultra and two office workers—Hyuck-ki Lee and Seok-joon Hong from Samsung’s Mobile Communications Business. Below, we explore their journey into the realm of astrophotography, and find out how the pair managed to capture the grandeur of the Milky Way with the Galaxy S20 Ultra.

A Young Man’s Journey to Becoming a Self-Made Astrophotographer

When Hong first started pursuing photography as a hobby, he used a film camera that he had received from his father. As he visited more and more shooting destinations, he found himself becoming increasingly immersed in the world of photography. In 2013, he and Lee traveled to Tanzania, where Hong got his first taste of astrophotography.
“I’ve always been interested in astronomy, and I even built my own telescope in high school,” Lee related. “I love how, with astrophotography, one day you can be shooting the moon from your living room, and the next you may be capturing a celestial phenomena that has never been caught on camera before. However, the idea that you could capture the night sky in all its glory with only a smartphone was a new concept to me.”
Glimpsing the stars shining bright on a pitch-black night is impressive enough, but actually trying to capture the sight with your camera can prove tricky. First, finding a spot to shoot that is unaffected by the light pollution caused by cities and large towns can prove difficult. Second, if you don’t remain alert and attentive, you risk missing the fleeting moment to get just the shot you’ve been waiting for. Third, you have no choice but to lug your heavy camera gear to whichever far-flung shooting destination you may have chosen.
But Hong and Lee report that the Galaxy S20 Ultra is going a long way towards alleviating those challenges. “Utilizing the camera on the Galaxy S20 Ultra has saved me from a lot of the difficulties that I thought were unavoidable,” said Hong. “A Galaxy S20 Ultra and a sturdy tripod are all a beginner astrophotographer really needs.”

How to Take Stellar Pictures on a Smartphone

The images of the night sky that the pair captured from the valleys and foothills between Jeollabuk-do and Gyeongsangbuk-do were so dazzling that it was hard to believe they were taken with a smartphone camera. “Even when a photograph is taken of the same thing, from the same place, at the same time, different photographers can produce varying products based on their differing perspectives and intentions,” Lee reported. “In many cases, differences in composition and angle combine to create a completely different piece of work.”
While taking photographs, it is also important to be familiar with your equipment and make the most of the features it offers. “The Galaxy S20 is definitely superior in terms of portability,” said Hong. “It also has the advantage of offering Pro Mode, which allows you to take photos manually and gives you more control over your settings, and ultimately the final results. I will definitely keep taking the S20 out into the field because of how it complements my DSLR camera.”
The Galaxy S20 Ultra offers improved low light photography and stability, producing extraordinary nighttime shots with minimal blur and noise. “Capturing good images of the night sky requires long exposure times­, and the Galaxy S20 Ultra is very well-suited to this kind of photography,” emphasized Lee. “Equipped with a 108-megapixel sensor and nona-binning technology for better low light performance, the camera on the Galaxy S20 Ultra is capable of capturing beautiful night-time photos.”
Hong and Lee also offered tips for those looking to try their hand at astrophotography. Lee recommended that burgeoning photographers start off simple, saying, “Static shots of constellations and the moon are easy to shoot, so are a good place to start. Make sure that you focus on the beauty of what you are trying to capture instead of the resulting pictures, and you will be rewarded with splendid pieces of work.”
“These days, chances for socialization are few and far between,” Hong commented. “So, for those looking to pass the time by getting into photography, I strongly recommend taking trips to remote areas with the Galaxy S20 Ultra. You don’t need a high-end DSLR camera to take great-quality pictures of constellations these days. You can also use astronomy apps to help you find constellations to take pictures of as well. From there, simply take out your Galaxy S20 Ultra and start creating special memories with your loved ones.”

How to Take Exceptional Night-time Photos with the Galaxy S20 Ultra

Before You Go
The best time to photograph the Milky Way is on a moonless night. A good flashlight and a backup phone battery are musts.

When You Get There
1) Set Up Your Equipment
When shooting in low light, you will need a tripod and either a remote shutter or timed shutter. The camera needs to be kept as still as possible to allow it to take in light.

2) Use Pro Mode
Most cameras aren’t automatically set up to take pictures of the stars. Switch from automatic to manual mode in advance so that you can then adjust settings like the ISO and shutter speed yourself between each shot.

3) Fine-tune the Shutter Speed
Apply a slow shutter speed, as your shutter needs to be open longer than normal in order to receive enough light for the shot. If you leave the shutter open long enough, you will capture star trails.

4) Adjust the White Balance
The White Balance setting adjusts the color temperature of your camera, ensuring that things that look white to your eye actually show up as white in the final product. A white balance of between 3500 and 4500 generally proves suitable for astrophotography.

5) Manage ISO Sensitivity
Your ISO setting determines the image sensor’s sensitivity to light. The higher the ISO, the brighter the photos. However, a higher ISO setting can cause unwanted noise and blocky pixels.

Tip for Saving Photos
While in Pro Mode, make sure to save photos as the RAW file type by navigating to Settings and turning on the ‘Save RAW copies’ feature. Photos saved as RAW files offer more editing options than those saved as JPGs or PNGs.
