Mid-price smartphones often sacrifice optical quality for the sake of savings, but Xiaomi Redmi Note 9 Pro became a real exception in this race. The device received a revolutionary system of four modules for its class, combined with intelligent artificial intelligence algorithms. Users who rated the features AI Quad Camera, received a tool that can compete with the flagships of previous years.
Shooting with this device has ceased to be just capturing the moment and has turned into a creative process controlled by neural networks. The developers paid special attention to the main 108-megapixel sensor, which, in combination with software, allows you to squeeze the most out of every frame. You will have to figure out how to properly configure the settings to get professional results without using third-party applications.
Camera system architecture and the role of artificial intelligence
System Redmi Note 9 Pro built around a powerful 108-megapixel Samsung HM2 sensor, which is the heart of the entire optical design. It is this module that is responsible for detailing in sufficient lighting conditions, allowing you to cut out small objects from the frame without losing quality. However, high pixel density alone does not guarantee great pictures, so engineers have implemented advanced algorithms AI Scene Detection.
Artificial intelligence analyzes the scene in a split second, determining what exactly you are shooting: a portrait, landscape, text or a night city. Based on this analysis, exposure, white balance and color saturation are automatically adjusted. If you're shooting food, the system will enhance warm tones, and when shooting the sky it will add depth and contrast.
- 📸 AI Scene Recognition Recognizes up to 30 different shooting scenarios automatically.
- 🧠 The neural network optimizes noise reduction, preserving skin textures and object details.
- 🎨Mode AI Color allows you to highlight the main subject, making the background black and white.
It is important to understand that enabling the function AI Camera in the settings, changes the processing algorithms for each image. Without this module, photos look flatter and dynamic range is significantly reduced. To get the most out of the device, you should leave automatic correction active in most modes, with the exception of professional manual control.
Detailed overview of auxiliary modules and their application
In addition to the main sensor, in the block AI Quad Camera There are three additional modules, each of which solves specific problems. The 8MP wide-angle camera with a 118-degree field of view is ideal for capturing architecture and large groups of people in tight spaces. This module is often underestimated, but it allows you to capture much more space than standard optics.
The 5 MP macro module opens up opportunities for capturing small details: leaf textures, water drops or jewelry. The depth of field here is minimal, which creates the effect of professional background blur even at open apertures. However, for this sensor to work, you need to bring the phone as close to the object as possible, maintaining a distance of 2-4 centimeters.
A 2 MP depth sensor works in tandem with the main module, creating a map of the distance of objects. This is critical for the operation of the mode Portrait Mode, where the background around the model is programmatically blurred. Without this sensor, the blur would look artificial, with errors at the edges of hair and clothing.
- 🔍 Macro Lens Allows you to focus on objects as close as 2 cm.
- 🌊 Wide-angle camera
118°indispensable for panoramic nature shots. - 👤 Depth sensor provides natural bokeh when shooting portraits.
108 MP mode settings and fine-tuning quality
Activating the 108-megapixel mode requires going to a separate section of the camera menu, as by default the phone groups pixels into 9-in-1 groups to improve light sensitivity. To get maximum detail, you need to go to Modes → 108 MP and make sure the resolution is set to maximum. In this mode, the pictures are huge in size, reaching 15-20 megabytes each.
When shooting in high resolution, it is important to use a tripod or a stable surface, as any micro-shift can lead to blur. Pixel stitching algorithms take longer to process than standard processing, so you shouldn't move your phone immediately after pressing the shutter. You will see a loading progress bar showing the progress of the file being saved.
Basic parameters for manual control
Even in automatic mode, it is worth paying attention to several key parameters that affect the final image. It's best to check white balance manually in mixed lighting to avoid unnatural green or blue casts.
The file format also plays a role: the choice between JPEG And RAW determines the possibility of subsequent processing. RAW files save all the information from the sensor, but require specialized software on a computer or tablet to unlock their potential.
| Parameter | Default value | Recommended value | Effect |
|---|---|---|---|
| ISO | Auto | 100-400 (daytime) | Minimum noise |
| Excerpt | Auto | 1/1000 s (sport) | Freeze motion |

- I don't know how to choose
⚠️ Attention: When shooting in 108 megapixel mode, the battery drains much faster, as the processor processes a data array 9 times larger than usual.
Low light shooting and night mode
Night photography on Redmi Note 9 Pro based on technology AI Night Mode, which combines multiple exposures into one frame. This allows you to pull out details from the shadows without the appearance of characteristic digital noise. To activate, just select the “Night” mode or wait until the camera itself offers it in low light.
The processing process takes from 2 to 5 seconds, depending on the amount of light. During this time, you cannot move the device, otherwise artifacts or blur will appear in the photo. Image stability algorithms work effectively, but physical stillness guarantees better results.
- 🌙 Night Mode Automatically increases shutter speed to capture more light.
- 🌌 AI Noise Reduction removes grain while maintaining clear outlines of buildings.
- 💡 Mode
Long Exposureallows you to create effects of light trails from cars.
Particular attention should be paid to shooting night portraits, where the face is illuminated with a flash or screen, and the background is processed separately. This creates the effect of studio shooting even outdoors. It is important not to overload the scene with artificial light in order to maintain the natural atmosphere of the night.
Secrets of night photography
To get the perfect night photo, find a place to rest your elbows or use a wall as a stand. Hold your breath as you release the shutter.
Video recording: possibilities and limitations
Video capabilities Xiaomi Redmi Note 9 Pro include recording in 4K resolution at 30 frames per second, as well as 1080p at 60 frames. Image stabilization is powered by electronic IS (EIS) algorithms that crop the edges of the frame to compensate for shake. This allows you to shoot dynamic scenes while walking or running without much “shaking”.
However, using 4K mode requires a high speed memory card and phone storage speed. If the memory card does not meet the speed class, recording may be interrupted or interrupted in parts. It is recommended to use cards of class U3 or higher for comfortable operation.
Sound recording also has its own characteristics: the built-in microphone picks up the voice well, but in windy weather extraneous noise may appear. Using an external microphone via the 3.5mm jack will significantly improve the quality of the audio track.
Video recording modes
There are several modes specifically optimized for different scenarios. Slow Motion allows you to slow down the action by 4 times, and the mode Time-Lapse Speeds up time for capturing sunsets or moving clouds.
☑️ Preparing to record a video
⚠️ Attention: Recording in 4K heats up the body of the device. When shooting for longer than 15 minutes, the phone may automatically reduce the frame rate or stop recording to protect components.
Professional Pro mode and manual settings
For those who want complete control over the shooting process, there is a mode Pro. Manual settings for ISO, shutter speed, focal length and white balance are available here. This is an indispensable tool for artistic photography, where automation does not always cope with non-standard situations.
For example, when shooting a starry sky, you need to set the shutter speed to 10-15 seconds and the minimum ISO to avoid noise. In normal mode, the camera will not provide this opportunity, since the algorithms will try to “improve” the picture, making the stars blurry spots.
- ⚙️ Manual Focus Allows you to shoot through glass or mesh.
- 🎚️ Settings
WB (White Balance)saves from color distortion under artificial light. - 📉 ISO manually controls the noise level in the frame.
In Pro mode, use the histogram to control exposure. If the graph is pressed to the right edge, it means that the image is overexposed and details in the highlights are lost.
