How to improve the camera on Xiaomi Redmi 9: secret settings

Budget smartphone segment is often criticized for mediocre quality of photography, but Xiaomi Redmi 9 was a pleasant exception, having managed to offer the user a versatile camera with a basic module of 13 MP. Despite the fact that the hardware of the device is limited in cost, the software allows you to squeeze out of the sensor much more than it is laid down by default. Correct calibration and understanding of image processing algorithms can turn ordinary pictures into quality photos for social networks.

In this article, we will not only take a closer look at the standard settings available on the menu, but also at more advanced methods, including the use of third-party software and engineering modes. You no longer have to put up with a soapy picture in low light or blurry details in the background. MIUI provides powerful tools that often remain hidden from the eyes of the average user.

Before you get into complex manipulations, it's important to understand the basic principles of how your device's camera works. The quality of the final image depends on a combination of factors: lens cleanliness, lighting, hand stability and, of course, HDR and noise reduction software algorithms. The key to Redmi 9 is proper exposure management, since the dynamic range of the sensor is physically limited. Let's start with the fundamental steps that every owner must take.

Basic preparation and purity of optics

The first rule of mobile photography that ignores 90% of users is the cleanliness of the lenses. The Redmi 9 camera features a protruding block of lenses that are instantly covered with greasy fingerprints when in your pocket or on your desk. These microscopic pollution scatter light, creating a fog effect, glare from streetlights and reducing overall sharpness of the frame.

Use a soft microfiber to wipe glass before every important shot. Don't rely on the edge of your clothes, because coarse fabric fibers can leave micro scratches on the oleophobic coating, which will only worsen the quality of your optics over time. A clean lens is the easiest way to instantly increase sharpness and contrast without changing the settings.

Also worth checking is the presence of a protective film on the body in the area of the camera. Factory stickers are often low in transparency and can create double reflection of light. If you notice glare inside the lens, carefully remove the residue of the glue or film using isopropyl alcohol.

⚠️ Warning: Never use aggressive household chemicals, acetone or alcohol in its pure form to wipe the camera lenses. This can destroy the anti-reflective coating and permanently damage the quality of the images.

After physical training, we go to software settings, and the standard Camera app has a lot of parameters hidden that are optimized by default for speed, not quality, and we need to change that balance in favor of detail.

Configuring the parameters of the built-in application

Open the camera app and go to the settings menu by clicking on the three bars in the upper right. First of all, pay attention to the aspect ratio. The default is often 4:3, but for social networks it is sometimes more convenient 16:9. However, for maximum quality and use of the entire matrix area, it is recommended to leave 4:3, since this is the native resolution of the sensor without digital crop.

The next important thing is resolution. Some versions of MIUI firmware may have an optimized mode by default. Make sure you choose the maximum resolution available (usually 13 MP for the main module). It's also worth activating the HDR Improvement function. Unlike automatic mode, manually selecting HDR allows the algorithm to better handle shadows and light areas, which is critical for contrasting scenes.

• 📸 Grid: Turn on the grid display (rule of thirds) in the settings, this will help to properly fram the picture at the time of shooting.
• ⏱️ Timer: Use a 3 or 5-second timer to remove the camera shaking when you press the down button, especially when shooting from a tripod.
• 🔊 Shutter sound: You can turn off the sound if you want, but remember that in some regions (Japan, Korea) this is impossible due to legal restrictions.

So, you'll pay special attention to Pro mode, which is built into the standard app, and it lets you manually control ISO, shutter speed, and white balance. This may seem daunting to the novice user, but this is where the potential for nighttime photography lies.

Use of PRO mode and manual settings

Pro mode gives you full control of exposure. The main parameter here is ISO, the sensitivity of the matrix to light. On Redmi 9, try to keep the ISO at a minimum (usually 50 or 100) in daylight. Increasing the ISO inevitably leads to digital noise that eats away at the detail and makes the picture grainy.

Shutter speed (designated S or Time) regulates the time that light hits the array. Short shutter speed (1/1000) freezes movement, but requires a lot of light. Long shutter speed (1/10 or longer) allows you to shoot in the dark, but requires absolute immobility of the phone. For long shutter speed, be sure to use a tripod or encircle the phone against a stationary object.

White balance (WB) allows you to adjust color temperature. Auto balance is often mistaken in artificial lighting, making the frame yellow or blue. In Pro mode, you can manually set the value in Kelvins or choose preset (sun, cloud, incandescent lamp) to produce natural colors.

Practice manual exposure control. Point the camera at the object, click on the focus icon and slider next to reduce brightness (EV), which will make the colors richer and remove the lights in the sky, which is especially important for landscape photography.

Secrets of night photography and work with light

Night shooting on budget smartphones is always a compromise. However, the Xiaomi Redmi 9 features a night mode that uses a multi-layered frame addition algorithm. To get the best result, turn on "Night Mode" explicitly, even if the phone offers automatic switching.

The main enemy of night photography is movement. When you use night mode, the phone takes a series of different exposures and combines them, this process takes 2-4 seconds. At this time, the phone should be fixed. Hold your breath and elbows against the body or use a tripod.

Avoid using flash for night portraits.built-in LED-flash on Redmi 9 gives a hard, flat light that knocks out the details of the face and creates a red-eye effect.

Experiment with light sources. Reflected light is always softer than straight light. Try shooting in store windows or under street lights, using them as a source of drawing light for your subject.

Third-party applications for empowerment

Xiaomi’s standard camera app, while functional, sometimes overly aggressively processes images, adding excessive sharpness and noise cancellation. Installing third-party software can dramatically change the way we process images. RAW-matrix.

One of the best solutions is the Google Camera (GCam), which has its ports working wonders with budget sensors, Google's HDR+ algorithms deliver dynamic ranges comparable to flagships, and the Redmi 9 (MediaTek Helio G80) has stable ports of 7.x or 8.x.

Another powerful tool is the Open Camera app. It's completely free, it's open source, it allows you to record sound from external microphones, and it also gives you access to video bitraids and manual settings that are hidden in the drain. For video, it's the best choice.

⚠️ Note: When installing GCam ports from unverified sources, there is a risk of malware device infection. Use only trusted forums (e.g., trusted forums, 4PDA or XDA Developers and files from well-known developers.

Also worth mentioning are post-processing apps like Snapseed or Lightroom Mobile.A shot taken on Redmi 9 often requires light contrast correction and saturation to look truly professional.

System optimization and data storage

The quality of the photo depends not only on the camera settings, but also on the overall performance of the system. If the phone's memory is full, the processor can not quickly process. RAW-data, leading to delays and potential reduction in noise reduction.

Clean the camera app cache regularly. Go to Settings → Apps → All apps → Camera → Memory → Clear the cache. This won’t delete your photos, but will reset temporary files that may have accumulated errors.

To store your photos, use a compression format that balances quality and size. If you're planning a serious processing, you can try to enable RAW save (if supported by the selected software), but for normal needs, a quality JPEG is quite sufficient. Remember to reserve the photo in the cloud to make room.

💡

Use a microSD card only to store your photo archive, not to shoot. The speed of writing to cheap cards may not be enough for 1080p video, which will lead to frame skipping.

Also make sure that MIUI memory optimization is enabled in the system. Close heavy applications before the camera starts to free up RAM for the image processing buffer.
