The Skill of Mobile Photography on Xiaomi Redmi 9

The budget smartphone segment has long ceased to be synonymous with mediocre image quality, and the Xiaomi Redmi 9 has become a prime example of how affordable technology can surprise with capabilities. Owners of this device often underestimate the potential of the main matrix at 13 megapixels, believing that serious shots need a flagship. However, the correct configuration and understanding of the principles of processing algorithms allow you to squeeze the maximum from even modest iron.

In this guide, we'll not only explore the basics, but also the hidden features of the MIUI Camera interface that are hidden from the eyes of the average user. You'll learn how to stabilize exposure, use manual settings for creative tasks, and trick the system into writing more details in the shadows. The quality of your photos depends not so much on the price of the gadget as on the ability to control the light.

Interface and basic camera settings

When you first start the Camera app, you see a minimalist interface where most of the functions are hidden behind the additional menus. To get a quality result, you need to immediately go to the settings through the hamburger menu in the upper right corner. It is important to turn off the model watermark if you plan to publish a photo in a portfolio, and check the resolution. By default, it can be set to a value other than the maximum.

The framing grid is a special focus, and the 3x3 grid helps you follow the rule of thirds, which makes the composition more harmonious instantly, and you can also activate the horizon level mapping in this section, which is critical for taking architecture and landscapes so that the lines of buildings don't fall down.

⚠️ Attention: “Improving” function» (AI Cam is on by default and aggressively saturates colors. For natural skin tones, it is better to turn it off when taking portraits, otherwise faces may become unnatural orange.

Setting the aspect ratio also affects the final file. Social media is the best format for 4:3, which uses the entire matrix area. If you choose 16:9, the camera will simply crop the top and bottom of the frame programmatically, resulting in a loss of useful resolution and detail.

Shooting modes and use cases

Modes menu swipe hides an arsenal of tools for different conditions. The standard Photo mode is suitable for 80% of situations, but in specific conditions it is better to switch to specialized algorithms. For example, Portrait mode on Redmi 9 uses software blurring of the background, since the device does not have a telephoto lens. The bokeh effect is created mathematically, so it is important to monitor the contrast between the object and the background.

Documents is the perfect way to capture documents and text fields, and it automatically aligns perspective, removes glare, and increases contrast, making it readable, eliminating the need to look for a flat light or hold your phone exactly parallel to the sheet.

In low light, the regular Night mode does wonders, but it requires immobility. The algorithm takes a series of different exposures and glues them together. If you flinch, the grease artifacts appear in the photo, so when you use night mode, you better elbow against your body or put your phone on a hard surface.

Professional mode and manual settings

For those who want to have complete control over the image creation process, the Xiaomi Redmi 9 has Pro mode, where you can set your exposure settings yourself, ignoring automatic algorithms, and is an indispensable tool for shooting in difficult light conditions where automation is wrong.

The key here is shutter speed. By increasing shutter speed (like 1/4 or 1/2 second), you let more light per matrix. This allows you to take vivid pictures in the evening without using a flash, but requires absolute camera immobility. Long shutter speeds require a tripod.

ISO regulates sensor sensitivity. On budget matrices like Redmi 9, high ISO values (above 800) make strong digital noise. In Pro mode, try to keep ISO at a minimum (ISO 100), compensating for the lack of light with longer shutter speed or aperture (although the aperture is fixed here).

The main secret of Pro-mode: focusing on infinity (mountain icon) allows you to take clear pictures of the starry sky, if you use long shutter speed and tripod.

White balance (WB) in manual mode allows you to adjust the color temperature of the scene. If the photo is too blue, move the slider towards warm colors. If yellow is towards cold colors, this gives a more accurate result than post-processing.

Shooting video on Redmi 9

The smartphone is capable of recording video at 1080p at 30 or 60 frames per second. For dynamic scenes such as sports or running, it is preferable to choose 60 fps, which will ensure smooth movement. However, in low light, it is better to switch to 30 fps, since the matrix will have time to capture more light per frame, reducing the amount of noise.

Stabilization in Redmi 9 software (EIS) works effectively when walking, but can cause a “jelly” effect when sudden movements. To record vlogs or reviews, it is recommended to use external microphones connected via a 3.5 mm connector or USB-C, since the built-in microphone is very noisy wind and echo.

⚠️ Note: For long-term recording of video in 1080p/60fps CPUs may overheat, which will cause the recording to automatically stop. take breaks or remove the case for better cooling.

There is also a 120 fps and 240 fps slow motion mode, but it is only available in low resolution 720p. Picture quality is noticeably worse here, so use timelapses only for art inserts, not for detailed recording of events.

Secrets of improving the quality of pictures

Even with limited optics, you can get great shots if you follow the simple rules of composition and lighting. First, always wipe the lens before shooting. Fat fingerprints create a soapy image and glare from light sources that are not software-enabled.

Second, use exposure correction. Touch the screen to focus, and a slider will appear next to the focus square. Lower it down to darken the frame. This will preserve the detail in the light areas (sky, white walls) and add drama, avoiding the red lights that often occur on Redmi 9 matrices.

Third, avoid digital zoom. Approaching the image with your finger ("pick") just cuts the center of the matrix and stretches it, turning the photo into a set of pixels, better to approach the object or take a picture from full distance, and then crop it in the editor — the quality will be higher.

💡

Use HDR manually in contrasting scenes (such as a person in front of a window). Automatic HDR can work slowly, and manual mode immediately balances light and shadows.
