Xiaomi’s advanced camera modules allow users to capture the grandeur of the night sky without the use of cumbersome professional technology. Built-in image processing algorithms coupled with high-quality optics allow for spectacular images of the Milky Way and individual star clusters right out of their pocket. However, automatic shooting modes often fail to cope with the lack of light, requiring the photographer to have a deep understanding of exposure settings.
To achieve the best result, you need to abandon the standard mode of “Auto” and switch to the advanced features of the “Camera” application. In this article, we will discuss in detail how to turn your Xiaomi into a powerful tool for astrophotography, what shutter speed parameters and ISO are critical, and why you can not do without a tripod in this case.
The success of night photography depends not only on the technical characteristics of the gadget, but also on the right choice of location and time. Understanding the physical processes that occur during long exposure will help you avoid common mistakes, such as digital noise or lubrication of objects. Let's dive into the world of night photography and unlock the potential of your device.
Choosing the right place and time to shoot
The first and most important step is to find a location with minimal light pollution. Urban illumination creates a lightning effect, making the stars virtually invisible to the matrix of the smartphone. The ideal option is to travel outside the city where the horizon is not blocked by buildings and the air is clear of smog.
The time of the shooting is also crucial: it is best to plan a photo shoot for the new moon or when the moon is low above the horizon, so that its light does not interrupt the glow of the stars. Astronomical night, when the sun is deepest below the horizon, provides the best conditions for fixing weak light sources.
⚠️ Avoid shooting in foggy or cloudy weather, as the moisture in the air will reflect city light, creating a “light dome” effect that will completely destroy the contrast of the shot.
Use specialized applications or web resources to track the phases of the moon and map light pollution, which will help you plan your trip in advance and choose a date when the conditions will be most favorable for your experiments with the camera.
Cold nights often contribute to a cleaner image with less digital noise, as the camera matrix heats up less during long-term operation.
Equipment required for stable shooting
The main enemy of night photography is the camera's jitters. Even the minimal movement of the smartphone during the shutter opening will lubricate the image, turning the stars into blurry spots. Therefore, using a reliable tripod is a prerequisite for taking sharp pictures.
If a professional tripod is not available, you can use any fixed supports: sandbags, stones or special phone mounts that allow you to fix the device on the railings or trees.
- 📸 Tripod or tripod: provides a rigid fixation of the smartphone in any position.
- 🔋 External battery: long shooting and screen operation in bright frost quickly plant the battery.
- 🧤 Thermal gloves: allow you to control the touch screen without cooling your hands in the cold.
- 🔦 Red flashlight: helps to navigate in the dark, without disturbing night vision and not highlighting the frame.
An additional benefit would be the presence of a remote control or the use of a self-start timer. Pressing the screen of a smartphone to start shooting can cause a micro-vibration that will spoil the frame, so remote control or a 3-5 second delay in start will solve this problem.
⚠️ Note: Do not rely on image stabilization (OIS/EIS) when shooting from a tripod, as in some Xiaomi models it can, on the contrary, introduce parasitic fluctuations with the complete immobility of the body.
Manual camera mode setting (Pro Mode)
To control the shooting process, you need to switch the camera to manual mode, which is denoted by the MIUI interface as "Pro" or "Pro." This is where you get full access to control the sensor parameters, which is critical for low-light shooting.
First, turn off all automatic enhancements and scenario modes. Your task is to give the camera a raw image with maximum detail. Focus should be put into manual mode (MF) and move the slider to infinity, but due to the peculiarities of the optics of smartphones, it is often necessary to slightly return it back to the stars become dots, not circles.
Why doesn't autofocus work at night?
The key is shutter speed. To shoot stars without tracks (lubrication due to the rotation of the Earth), the rule is "500." Divide the number 500 by the focal length of your lens (the equivalent of 35 mm) to get the maximum shutter speed in seconds. For most smartphones, this value is between 10 and 30 seconds.
The ISO parameter is responsible for the sensitivity of the matrix. Increase it until the stars are clearly visible in the preview, but watch for the appearance of digital noise. The optimal range for modern flagships Xiaomi is often a value of 800 to 3200 units.
💡
Use the RAW (DNG) format in your camera settings. It stores much more information about light and color, which has huge benefits when you process the image later on on your computer.
Specifics of using night mode
Many users are wondering if you can use automatic Night Mode, and the latest versions of the HyperOS shell and MIUI have improved their algorithms significantly, and this mode can give a decent result for social networks without complex post-processing.
Night mode takes multiple images with different exposures and glues them together using a computational photo to suppress noise. This is convenient if you don't have a tripod, but you can point your phone against a stationary object. However, for serious astrophotography, manual tuning is still preferable.
Some models, such as the Xiaomi 13 Pro or Xiaomi 14 Ultra, have a special “Long Shutter” or “Starry Sky” mode that automatically adjusts the settings for shooting the Milky Way.
Table of optimal settings for different conditions
To organize knowledge, consider recommended parameters for different shooting scenarios, remember that these values are starting points, and the creative process requires experimenting with a particular instance of your device.
| Script | Excerpt (sec) | ISO | Focus | Format |
|---|---|---|---|---|
| Bright stars (without the Milky Way) | 10-15 | 400-800 | Manual (infinity) | JPEG / RAW |
| Milky Way (wide angle) | 20-25 | 1600-3200 | Manual (bright star) | RAW (DNG) |
| Cityscape at Night | 2-5 | 100-200 | Auto/Manual | JPEG |
| Light tracks (cars) | 15-30 | 50-100 | Hand-held | JPEG |
Note that when you increase the ISO, the dynamic range of the image decreases. If there are bright light sources in the frame (lights, moon), they can turn into white spots without details. In such cases, it is better to underexpose the frame (make it darker) to keep the details in the lights, and the shadows stretch out during processing.
The use of RAW is especially relevant for scenes in the Milky Way, where every detail of the color and structure of galactic dust is important. The standard JPEG aggressively compresses data, losing important information.
☑️ Checklist before shooting
Post-processing and noise reduction
Shooting stars on a smartphone is only half the way, and the second, equally important, part is processing the material, and the manual images often look pale and require corrections in black and white levels, as well as increased saturation.
For processing RAW-So, the files on the device are great for applications like Lightroom Mobile or Snapseed, which allow you to work with curves, adjust color balance and, most importantly, apply noise reduction.
Noise reduction algorithms should be used carefully. Excessive smoothing will turn stars into soap spots, depriving the image of detail. The perfect balance is achieved when noise in the dark areas of the sky becomes barely noticeable, but the stars retain their sharpness.
- 🌌 Exposure correction: carefully raise shadows to reveal details of the Milky Way.
- 🎨 White Balance: Shift the Temperature to the Cold Side to Increase the Deep Space.
- 🔍 Clarity and structure: Add a little sharpness to highlight stars against the sky.
If you shoot in JPEG format, editing options will be limited, as the file is already compressed and processed by the camera algorithms, in which case the focus is on color correction and framing.
⚠️ Warning: When processing, avoid the appearance of "artifacts" around bright stars that can occur with aggressive contrast and clarity increases.
