Shooting a smartphone night light has long been considered the domain of professional cameras with huge zoom lenses, but today’s flagships and even the mid-range Xiaomi, Redmi and POCO lineup are equipped with artificial intelligence algorithms that allow you to capture craters and seas without additional equipment.
In this article, we will discuss why automatic mode often turns the Earth’s satellite into a white spot, and how to use manual exposure settings correctly, you will learn what ISO parameters and shutter speeds are necessary for a clear picture, and whether you should use a tripod to get a professional result.
We’ll look at not only the standard camera app, but also specialized tools that unlock the potential of your device’s matrix.Preparation for shooting begins long before you hit the downhill button, so it’s important to consider weather conditions and the position of the moon in the sky.
Why the Moon is a White Spot
The main problem with automatic mode is that HDR and nighttime imagery algorithms attempt to artificially illuminate dark areas of the frame. The camera sees the black sky and decides that it needs to raise the brightness, causing it to overexpose the bright object, the moon. The surface details are simply burned out by light, turning into a uniform white circle.
In addition, autofocus systems are often lost in the dark, trying to find contrasting boundaries. If there are no clear foreground objects in the frame, the lens can walk without fixating on infinity, which is why manual focusing is key to obtaining a sharp image of a satellite.
⚠️ Note: Using digital zoom (two finger pinches) without an optical approximation drastically reduces quality.Try to use only optical zoom, if you have one in your model.
Understanding the physics of the process helps avoid errors. The moon is illuminated by the sun, so it's bright enough to be captured at a short exposure, unlike stars or the Milky Way. Your job is to trick smart algorithms into operating in a mode suitable for a bright object against a dark background.
Preparation of smartphone and equipment
The smartphone screen is the brightest object in view at night, and its glow can knock down exposure settings and interfere with viewing. It is recommended to reduce the brightness of the display to a minimum or turn on a special mode for working in the dark if it is available in your MIUI or HyperOS shell.
Stabilization is the second critical point, and even the microscopic tremors of the hands when you use a telephoto lens will lubricate the frame, and if you don't have a professional tripod, you can point your phone against a railing, a rock, or use a sandbag, and make sure that the device is completely still when you're shooting.
- 🔋 Charge the battery to 100% as nighttime camera operation and screen usage quickly land the battery.
- 🧼 Wipe your optics with microfiber to remove the greasy traces that create glare from the moon's bright light.
- 🌡️ Let the phone cool if it was warm to avoid fogging the lenses when out in the cold air.
It is also worth checking if there is free space in memory. shooting in maximum resolution or in RAW format takes up significantly more space than regular shots. Clean the gallery in advance or make sure that the memory card has sufficient volume.
☑️ Checklist before exit
Set up a standard Xiaomi camera
Xiaomi smartphone owners are lucky because the standard camera app already has a powerful Pro mode built in. Switch to the mode menu and select Pro (or Manual), which gives you full control over the sensor parameters, which is necessary for correct exposure.
First, set your focus. Press the AF icon and turn it into the MF (Manual Focus) position. Move the focus slider to the far right, to the mountain or infinity icon, which ensures that the focus is fixed to a distant object.
Next, you need to adjust the exposure pair. Set the ISO value to a minimum (usually 50 or 100). This will reduce the sensitivity of the matrix and remove digital noise. Shutter speed (S or Time) should be selected experimentally, starting with values of 1/125 or 1/250 seconds. If the moon is still too bright, reduce the shutter speed (for example, to 1/500).
| Parameter | Recommended value | Impact on the photo |
|---|---|---|
| ISO | 50 - 100 | Reduces noise, makes the sky black |
| Excerpt (S) | 1/125 - 1/1000 | Freezes traffic, removes light. |
| Focus (MF) | Infinity | Provides maximum sharpness |
| White balance | 4000K - 5000K | Makes the Moon Color Natural, Not Yellow |
Be sure to turn off the flash and various beauty effects that can interfere with the image processing process, and it is also recommended to set a timer for 3-5 seconds or use voice control to avoid shaking the phone when you press the screen.
💡
Use a Bluetooth headset or wired volume button headphones as a remote descent. This will eliminate any physical touch of the smartphone.
Use of PRO mode and manual settings
Xiaomi's Pro mode bypasses the limitations of automatic intelligence. When you set the parameters manually, the camera stops trying to "improve" the image by storing the original data from the matrix, which is especially important for shooting contrasting objects.
Notice the histogram, if it's available in your interface. The graph should not be on the right edge, which is evidence of overlighting. The ideal exposure for the moon is when a bright spot has clear boundaries and visible texture, rather than blending into the background.
⚠️ Attention: If you change the zoom, the focus may be lost. Always check the position of the slider. MF After you have brought the image up.
For owners of telephoto-zoom phones, switch to the lens with the highest focal length (usually designated as 2x, 5x or 10x) before setting up exposure. The digital zoom inside Pro mode also works better than normal, thanks to more flexible data processing.
If the standard Pro mode seems difficult to you, try taking a series of shots with different shutter speeds (bracketing), and then select the best frame or combine them in the editor. This will increase the chances of getting the perfect result the first time.
Third-party astrophotography applications
The standard functionality is sometimes not enough, especially on budget models Redmi or POCO, where algorithms can be cut down, and in such cases, Google Play apps like Open Camera, ProCam X or Manual Camera: DSLR come to the rescue.
Open Camera is completely free and allows you to access the Camera2 API, which gives you full control of the hardware. In the application settings, you need to activate support for the Camera2 API, if not done by default, this will open access to manual control of shutter speed and focus even where the standard camera hides them.
- 📸 Open Camera: The Best Free Option With Open Source and Support RAW.
- 🌟 ProCam X: user-friendly interface and advanced tools for working with histogram.
- 🎞️ Manual Camera: Emulation of the SLR camera interface for the usual control of settings.
Using third-party software, you can also save your images in RAW (DNG) format, which contains raw data from the matrix, which provides a huge post-processing opportunity, and you can pull the details from the shadows and lights on your computer using Lightroom or Photoshop.
Why do you need a RAW format?
Post-processing and image improvement
Even a perfect source often requires minimal fine-tuning. Upload your photo to any curve and level editor, such as Snapseed or Lightroom Mobile. First, reduce the light tones (Highlights) and white to show the details in craters.
Then add a little contrast and structure (or clarity) to the surface, which will emphasize the topography. Be careful with saturation: The moon should not be bright yellow or orange unless you specifically shot it near the horizon, where the atmosphere is coloring the light.
And the imagery is also important, so you can remove the black space around the satellite, and leave it as the centerpiece of the composition, and if the image is noisy, use noise reduction tools, but don't overdo it to make sure that the texture is not plastic.
For advanced users, there is a method of stacking, or you can take a short video of the moon or a series of 50-100 photos, then in a program on a PC (for example, AutoStakkert) combine the best shots, which will significantly improve the detail and remove atmospheric distortion.
💡
The main secret of high-quality lunar photography is not the number of megapixels, but in the correct exposure (low ISO, short shutter speed) and absolute immobility of the camera.
