Professional camera setup Xiaomi Mi 8

The Xiaomi Mi 8 was a true bestseller of its time, thanks in large part to the advanced photography system inherited from the company's flagship models. However, to get studio-quality shots, it's not enough to just point the lens at the subject and press the downhill button. Standard MIUI algorithms often recycle the image, adding excessive noise cancellation or unnatural blurring that not everyone likes.

Deep tuning unlocks the real potential of 12-megapixel modules with optical stabilization and dual zoom. In this article, we will explore how to switch to manual control, adjust exposure correctly, and avoid the typical low-light shooting errors. You will learn how to manage focal length and white balance the way professionals do.

Owners of the device often do not realize that the hidden features of the interface can significantly improve texture detailing and color reproduction. Some hidden features may require the activation of developer mode or installing third-party modules. Let's move on to practical steps to optimize the performance of your camera.

Basic interface settings and framing grids

Before you start to get into the complex manipulation of ISO and shutter speed, you need to get the main interface in order. The standard viewfinder is often overloaded with unnecessary elements that distract from the composition of the frame. The first thing you should do is to include a framing grid that is based on the rule of thirds, the fundamental principle of building a harmonious image.

To do this, launch the Camera app and click on the menu icon (three horizontal bars) in the upper right corner. In the list that opens, select Settings. Find Grid or Grid Lines and activate the switch. Now, when you hover the camera over the subject, you will see nine equal sectors, which will help you place the horizon strictly parallel to the edges of the frame, and the main objects at the intersection of the lines.

You should also pay attention to the "Shut Sound" setting, which in some regions where privacy laws apply, you can't turn that sound off software without changing the region in your settings, but if your smartphone allows, turning off the sound will help you to make quiet reporting.

Activation and fine tuning of Pro-mode

The only real control over the image is the manual mode, which is called Pro in the MIUI shell. Unlike the automatic mode, where the artificial intelligence decides which shutter speed to choose, here you get full access to the matrix. To switch, swipe the bottom panel of modes to the right all the way to the end, or select "More" and find the "Pro" icon.

In this mode, you can set the WB (white balance), ISO (sensitivity), S (sustainability), AF (focus) and T (telephoto lens) settings. Changing the white balance allows you to adjust the color temperature of the scene. If the picture goes into blue, the slider shifts towards the yellow spectrum, and vice versa. This is critical when shooting indoors in mixed light.

ISO is responsible for sensor sensitivity. In good light conditions, always keep it at a minimum (usually ISO 50 or 100) to avoid digital noise. An ISO increase is only necessary in the dark, but remember: the higher the value, the more grain will be in the photo.

💡

Use a tripod when shooting in Pro-mode with long exposure, which will keep the ISO at a minimum, keeping perfect detail even at dusk.

Controlling shutter speed (S) opens up creative possibilities. Short shutter speed (e.g. 1/1000s) allows you to freeze the movement of a running person or drops of water. Long shutter speed (1/4s or longer) blurs movement, creating the effect of silky water or light plumes from car headlights.

Working with HDR and Night Mode

The high dynamic range (HDR) technology in the Xiaomi Mi 8 works by creating multiple frames with different exposures and then combining them. This allows you to save details in both light areas of the sky and dark shadows. In newer versions of MIUI, HDR mode is often turned on by default (Auto HDR), but it can be activated forcefully through the top menu of the viewfinder.

Night Mode is a story in its own right, and it uses machine learning algorithms to add up a lot of frames taken at different shutter speeds, and to get the best result, you have to hold your smartphone absolutely still. 3-4 So, any shaking of your hands will lubricate the final image.

⚠️ Warning: When using night mode in extremely low light, do not use zoom. Digital zoom in this mode catastrophically reduces the quality of the final image, turning it into a set of color noises.

It's also worth mentioning the Mirror Magic feature, or Portrait Improvement, which is often built into the night modes of the front camera. It smooths the skin, but can remove important textures. For realistic shots, it's better to minimize the intensity of this effect or turn it off completely in beauty settings.

Focus and Expo Measurement setting

The Xiaomi Mi 8 autofocus system features Dual Pixel technology, which provides fast and accurate focusing even in low light. However, in complex scenes, automation can err by focusing on the foreground instead of the main object.

Touch the screen at the point you want to make it clearer, and next to the focus square, you'll see a slider that adjusts the exposure (sun), and you'll pull it down and you'll darken the frame, which often helps to make the colors more saturated and contrasting, especially when you're shooting sunsets or bright objects.

For static objects such as documents or goods, the “Push to Focus” feature is useful. In the camera settings, you can choose the focus mode: frame-by-frame (AF-S) or continuous (AF-C). For most scenarios, frame-by-frame is better, since it prevents the camera from constantly “scouring” for an object.

Image preservation and resolution formats

By default, the Xiaomi Mi 8 shoots in JPEG format with an aspect ratio of 4:3, which corresponds to the full size of the matrix. However, in the settings, you can change the ratio to 16:9. It is important to understand that when you choose 16:3, the camera does not use the entire sensor area, but simply trims the top and bottom of the frame, reducing the final resolution of the photo.

For users planning to further process images in graphics editors, the RAW format may be interesting. This format saves raw data from the matrix without using compression and noise reduction algorithms. RAW files take up much more space (about 20-25 MB versus 3-5 MB for JPEG), but give great freedom in color correction and exposure.

To activate shooting in RAW, go to Pro mode and at the top of the screen click on the RAW icon. It will light up in yellow to confirm activation. Now all pictures taken in this mode will be saved in DNG format, which is read by most professional editors.

Solving Common Problems: Blurring and Noise

One of the frequent complaints of Xiaomi Mi 8 owners is the excessive blurring of details, especially around the edges of the frame, which is the result of aggressive noise reduction algorithms, and you can partially solve this problem by turning off Image Improvement in the camera settings, if this option is available in your firmware version.

Another problem is the "soap" with digital zoom. Xiaomi Mi 8 features a 2x optical zoom that switches the camera to a second module. All values between 1x and 2x, as well as above 2x, are digital zoom that just crops and stretches the picture. To maintain quality, it's better to shoot on the main camera and crop the shot later in the gallery than use a zoom slider.

⚠️ Attention: Frequent use of zoom in a camera application can lead to overheating of modules and temporary decrease in the performance of the image processing processor.

If the photos are systematically dark even during the day, check if the protective film is not glued to the area around the lenses. Some users, trying to protect the screen, accidentally overlap the light sensor or part of the optics, which knocks the automatic exposure.

Use of third-party applications for shooting

The standard MIUI camera app is functional, but sometimes third-party developments give more control. One of the best Android solutions is the Google Camera (GCam). Google Camera ports for Xiaomi Mi 8 work wonders with dynamic range and night shooting using Google's HDR+ algorithms.

Installation of GCam requires downloading APK-The file is adapted specifically for the Snapdragon 845 processor installed in the Mi 8. After installation, you also need to download the configuration file (.xml), which prescribes the correct settings for the Sony sensors installed in your device.

Another great alternative is the Open Camera app. It's completely free, open source, and allows you to fine-tune the bitrate of video, support for external microphones, and manual focus control, which sometimes works more accurately than in a stock camera.

💡

Installing a ported version of Google Camera (GCam) is the most effective way to instantly improve the quality of night shots and HDR on Xiaomi Mi 8 without getting root rights.
