How to take a picture of the night sky on Xiaomi: the complete guide

Xiaomi’s modern smartphones have long since ceased to be just communication devices, becoming powerful tools for mobile photography. Many users do not even suspect that their Mi or Redmi is able to capture the Milky Way if you approach the process correctly. Standard automatic mode often does not cope with low light, but manual settings allow you to unlock the potential of the matrix.

To get a good shot of the sky, it is critical to understand the physical limitations of your gadget’s optics. A small smartphone array collects less light than a professional camera, so it requires longer exposure and complete immobility. In this article, we’ll look at how to turn your Xiaomi into an astrophotographic tool.

You'll learn about the hidden features of the camera, the right location, and the software algorithms that work magic in the dark. You don't have to be a professional to take the first shot that will make friends jealous. You have to be patient and technically knowledgeable.

Preparation of equipment and choice of location

The first and most important step is to find a place with minimal light, and city lights create a dome of light that completely hides the stars, making it pointless to shoot. 20-30 Explore the real potential of the night sky.

The second critical element is fixing the device, and any tremor of the hands that you hold for a long time will turn the dots of the stars into blurred lines, and the ideal solution is to use a tripod with a universal clamp for a smartphone, and if you don't have a tripod, you can point your phone at a fixed object, a rock, a parapet, or a sandbag.

⚠️ Warning: When you install your smartphone in cold air at night, watch for condensation on the lens. A sharp temperature drop can fog the lens through the lens 10-15 minutes of shooting, spoiling the entire series of frames.

It is also worth checking the battery power in advance, as the cold and screen work quickly put the battery down. It is recommended to carry a superbank, especially if you plan to shoot in RAW format or use high-bitrate video modes. A frozen phone can turn off at the most inopportune moment.

Configure Pro mode in a standard application

Xiaomi’s standard Mi Camera or Google Camera camera app has a powerful manual mode, denoted as Pro. This is where the tools needed to control exposure are located. Automation here is powerless as it seeks to brighten the frame by creating digital noise instead of the blackness of the sky.

You have to manually set the shutter speed. To take a picture of stars, the optimal value would be a range of 15 to 30 seconds. Longer exposure would cause the stars to turn into short tracks because of the Earth's rotation, rather than remain dots, a phenomenon called the 500 rule in photography.

The sensitivity of the matrix, or ISO, also requires attention. Don't push it to the maximum, otherwise the photo will be covered with color noise. The optimal range for modern Xiaomi sensors is between 800 and 1600 units. Try to take a test frame and assess the level of digital grain.

• 📸 Focus: Switch to manual (MF) Then move the slider to the extreme position (infinity), then slightly back.
• ⏱ Exposure: Set the value within the limits 15-30 stag-star.
• ☀️ White balance: fix the value around 3500-4000K for the natural color of the night sky.
• 🔇 Timer: Be sure to include the delay of the descent in 3-5 seconds to avoid shaking from pressing.

Using Long Exposure Mode on Xiaomi

Owners of Xiaomi and Redmi Note flagship models have access to a special Long Exposure mode, which is often hidden in the “More” menu, which uses artificial intelligence algorithms to combine many frames, allowing you to get vivid pictures even without a tripod, although its presence is still preferable.

The algorithm works by creating a series of images with different exposures and then overlaying them. This effectively removes digital noise and pulls details out of the shadows. Unlike pure manual mode, here the smartphone decides how to process light flows, which makes life easier for beginners.

But it's worth remembering that software processing can sometimes go overboard, making the sky unnaturally bright or adding artifacts. For creative tasks, this can be a plus, but for realistic astrophotography, it's better to use a hybrid approach: shoot a series in Long Exposure, and then process the source materials.

Shooting in RAW format for post-processing

To get a professional result, you need to shoot in RAW format. In the Xiaomi camera settings, this format can be called.dng. Unlike compressed JPEG, the RAW file contains raw data from the matrix, storing all information about color and light.

This gives you a tremendous advantage in post-processing, so you can pull shadows without losing detail in the lights, and remove noise without losing the sharpness of the stars. The standard JPEG that the phone produces is already compressed and processed with noise reduction algorithms, which often results in a plastic-like sky.

Processing these files requires special applications such as Lightroom Mobile or Snapseed. RAW-files weigh much more and take up a lot of space, so take care of the free space in the memory of the device in advance.

Problems of focusing in the dark

The most common mistake in shooting stars is to focus incorrectly, and in total darkness, autofocus can't find contrasting boundaries and starts to "scour" without being obsessed with sharpness, making the stars look like blurred spots.

The solution is to manually focus. Point the camera at the brightest object in the frame (bright star, distant lantern or moon), tap the screen to capture the focus, and then switch the slider to manual mode, fixing the position.

There's a professional life hack: turn on the camera's settings with the feature "Peaking" that illuminates the contours of objects that are in focus with a bright color (usually red or green), and when the stars become small colored dots, the focus is captured perfectly.

💡

Use 2x or 3x zoom when focusing on a bright star, and a larger image on the screen will help you adjust the sharpness more accurately, after which the zoom can be removed for framing.

Common Errors and How to Resolve Them

Even with perfect settings, you can get a marriage if you ignore external factors. Often users forget to turn off the flash, which, when shooting at night, only illuminates the foreground and creates a parasitic light on the lens. The flash should be turned off always.

Another common problem is the use of digital zoom, where fingers approaching the image on the screen is just a crop of the matrix, which drastically reduces quality and increases noise, and you only zoom optically if your phone has a telephoto lens, or you can frame a finished shot.

⚠️ Warning: Do not wipe the camera lens with a cloth in the cold. Static electricity and micro scratches from frozen dust can permanently damage the quality of the optics. Use a special liquid and let the phone warm up.

Avoid shooting against the wind if the phone is on a light tripod. Even microscopic vibrations from the wind in 20 seconds of exposure will make the picture sluggish. Press the tripod with something heavy or use your body as wind protection.

💡

The main enemy of night photography on a smartphone is not a bad camera, but motion. Any vibration during exposure destroys the detailing of stars.
