How to take a picture of the night sky on the phone shaomi: a professional approach

Nightly shooting of the starry sky on a smartphone is often perceived as the lot of expensive flagships, but modern devices Xiaomi and Redmi can do wonders even in low light. Many users mistakenly believe that to get a quality picture of the Milky Way requires a SLR camera, but the image processing algorithms MIUI and HyperOS work magic, allowing you to capture the cosmos from the palm of your hand.

The key is not just the hardware of the matrix, but the proper use of manual settings that are hidden from the eyes of the average user in automatic mode. You will have to learn how to control shutter speed, light sensitivity and focus to turn dark noise into clear stars, stabilization in this process plays a secondary role, giving way to rigid fixation of the device.

In this article, we will take a closer look at the process of preparing, tuning and direct shooting so that you can get a result that even professionals are not ashamed to show. Forget about the blurred frames and the illuminated spots – now we will learn to write with light using only the capabilities of your Xiaomi smartphone.

Choosing the Right Time and Place for Astrophotography

The first and most critical step is to find a location, and the city light creates a powerful light in the sky, turning stars into barely visible points or completely hiding them. 15-20 mile long enough to stop light noise from dominating the natural glow of stars.

It is important to consider the phase of the moon: the full moon acts as a powerful spotlight, blurring the contrast of the Milky Way. The ideal time to shoot is the new moon period or when the satellite is low above the horizon. Use specialized astrophotography applications to plan the position of the galaxy in advance.

⚠️ Warning: Never go out on a night shoot alone in unfamiliar places. explore the route in advance, bring a power bank and warm clothes, as the process can take several hours.

Weather conditions also dictate their rules. High humidity can create a foggy haze that will scatter the light of the stars, making the sky white. Atmospheric transparency is a key factor, and often after rain or in frosty winters, the air becomes cleaner, which favors the detail of the image.

Equipment required for stable shooting

The main enemy of night photography is any movement, even microscopic movement. You can't take the night sky off your hands because of the long shutter speeds needed to store light. You'll need a reliable tripod or an alternative support that is guaranteed to stay in the wind.

If you don't have a professional tripod, you can use a sandbag, a rock, or you can lean your phone against a stationary object, putting a fabric in order to level the horizon, and the main thing is to ensure that the gadget is absolutely still throughout the exposure, which can last from 4 to 30 seconds.

• 📷 Tripod with a reliable clamping for a smartphone.
• 🔌 External battery (Power Bank) in case of long shooting.
• 🧤 Thin gloves to control the screen in the cold season.
• 🔦 Red flashlight, so as not to disrupt night vision and not to shine in the frame.

You also need to get a remote control or use a self-start timer. Pressing your finger on the screen causes vibration, which will inevitably lubricate the frame when you start exposure. Bluetooth button or timer for 3-5 seconds will solve this problem.

Camera setup: transition to professional mode

The standard automatic Night mode often aggressively suppresses the image, turning stars into soap spots. To get a quality result, switch to PRO (Professional) mode. In the Xiaomi camera interface, it is usually located on the top menu or in the list of additional modes.

In this mode, you have complete control over the sensor, and your task is to balance the amount of light you capture with the amount of digital noise, and the automation won't help, because it doesn't know that you're shooting stars, not street lamps.

💡

Use RAW mode in your professional shooting settings if you plan to further process it in Lightroom, which will save you as much color and light data as possible.

Note the save format. If you're new, start with a high-quality JPEG, but for serious work, you'd better set up saving in RAW (DNG) right away. This format saves uncompressed data from the matrix, giving you a huge margin when you post-process it.

Manual setting of parameters: ISO, shutter speed and focus

The most important step is to adjust the exposure. ISO is responsible for the sensitivity of the matrix. For the night sky on Xiaomi smartphones, the optimal range is between 800 and 3200. Raising ISO above 3200 is often pointless, since digital noise will completely “eat” the part.

Shutter speed (denoted as S or T) determines the time the matrix collects light. Stars are optimal for 10 to 30 seconds. However, remember: the longer the shutter speed, the greater the risk of smear due to the rotation of the Earth. On phones without tracking, stars can turn into short tracks when shuttered for more than 25 seconds.

Focus is critical. Autofocus in the dark won't work. Switch focus to manual mode (MF) and move the slider to infinity position (mountain icon). However, on many smartphones, infinity is not at its extreme, but a little earlier. Take a test shot of a bright star and adjust the focus so that the dot is as small as possible.

⚠️ Attention: Don't trust your phone's screen 100%. The brightness of the screen can distort the perception of focus. Use zoom 5x-10x when pointing at focus for maximum accuracy.

Comparison of shooting modes on different Xiaomi models

Different smartphone models handle night scenes differently. Xiaomi's flagship 13/14 Pro series have larger sensors and optical stabilization, allowing for less noise shooting. Budget models of the Redmi Note series require more ISO tuning.

Older models don't have to despair. Even on older devices, you can get a decent result if you lower your ISO to 800 and increase your shutter speed, offsetting the light with time. The MIUI Camera algorithms are constantly updated, improving performance even on old hardware.

Use of third-party software and applications

Xiaomi’s regular camera app is functional but has limitations, such as being able to force noise cancellation that cannot be turned off, and for advanced users, it’s recommended to consider installing apps like Open Camera or Manual Camera RAW.

These applications allow you to completely disable the software processing, give you access to the focal length in millimeters and provide a histogram in real time. The histogram is the astrophotographer's best friend, showing if the picture is overlit and if there are details in the shadows.

Installing third-party software requires permissions to access the camera, but the result is worth it. You get full control of the Bayer pattern and you can squeeze the maximum it is physically capable of out of the matrix without artificial intelligence interference.

Post-processing: how to improve the picture

A raw file (RAW) from a phone's camera can look pale and gray. That's OK. Real magic happens when you process it. Use the mobile versions of Lightroom or Snapseed for correction.

First of all, work with contrast and clarity. Carefully raise the Texture or Structure to emphasize the stars. Be careful with the Noise slider: removing it completely will make the sky plastic, leave some graininess for naturalness.

• 🌑 Raise the Shadows to reveal details of the Milky Way.
• ✨ Add Clarity to highlight star clusters.
• 🎨 Adjust the white balance by shifting it into the cold spectrum (4000K-4500K).

Don't overload it. The sky shouldn't be bright blue or purple unless it's an artistic idea. The natural colors of space are shades of black, gray and dull yellow glow of the galactic center.

💡

The quality of night photography depends on 50% of shooting and 50% of competent post-processing. RAW-file.

Frequent mistakes when shooting stars on the phone

One common mistake is using digital zoom, where you can pinch the image and cut the pixels, drastically reducing the quality, and shoot on the main module (1x) and then frame it.

Also, users often forget to wipe the lens before shooting, and during the day, the greasy spots are invisible, but at night they create powerful glare from any light source, spoiling the entire frame. Always carry a microfiber with you.

⚠️ Warning: Turning on a flash in nighttime shooting is useless for stars, but can illuminate the foreground or reflect off nearby objects, spoiling the atmosphere of the frame.

Ignoring the horizon is another problem. The curved horizon in the sky image immediately catches your eye and destroys the composition. Use the grid in the camera settings (Settings → Grid 3x3) to align.
