Xiaomi’s Boke: What it is and how to get the perfect effect

Xiaomi smartphone owners often notice a specific artistic effect in photos taken on camera that gives them a professional look. This effect is called bokeh, and it has become the standard for modern mobile photography, allowing you to separate the main subject from the background. In Xiaomi and Redmi devices, the implementation of this mode may differ depending on the version of the MIUI or HyperOS operating system, as well as the hardware capabilities of a particular camera module.

Understanding background blur can help you take better images without using expensive mirror optics. AI algorithms built into firmware analyze the depth of a scene in real time, creating the illusion of a shallow depth of field. However, to get a truly high-quality result, the user needs to know not only the theoretical foundations, but also the practical nuances of working with the camera software.

In this article, we will explore what lies behind the term “boke,” how to use portrait mode correctly, and what settings are hidden in the camera menu, learn to avoid common mistakes, such as incorrectly highlighting the contours of an object, and learn how to adjust the blur force after the photo is taken, which will turn your smartphone into a powerful tool for creating content.

Physical nature of the effect and digital imitation

The term "boke" comes from a Japanese word meaning "blurring" or "fog," and in classical photography, it describes the pattern of blurring objects outside the field. In traditional photography, this effect is achieved due to the physical properties of the lens: wide aperture and focal length. The larger the physical aperture (less than f), the more blurred the background, creating a soft, pleasing glow around the light sources.

In Xiaomi smartphones, the physical aperture is often fixed or limited in range, so the main job is taken by computational photography. The camera uses data from multiple lenses (main and telephoto lens or depth sensor) to build a depth map of the scene. Based on this map, the software artificially blurs the pixels, simulating the operation of a wide-angle lens with an open aperture.

⚠️ Attention: Digital bokeh is always an imitation, so when shooting complex objects (hair, transparent objects, grids) artifacts can arise. The algorithm can not always accurately determine the boundary between the object and the background, which leads to "cutting" edges or unnatural blurring.

Modern models like the Xiaomi 13 Pro or Xiaomi 14 Ultra are equipped with large sensors and variable apertures, which allows you to get an optical bokeh close to professional. However, even in the budget models of the Redmi Note series, algorithms work quite efficiently if the lighting conditions and distance to the object are met.

💡

For best bokeh effect, try to keep the distance between the subject and the background at least 1-2 meters. The further the background, the stronger and more natural the blur will be.

How to Enable Portrait Mode on Xiaomi

Activating portrait mode is the first step to taking bokeh photos. The camera interface in the MIUI and HyperOS shells is intuitive, but has its own peculiarities depending on the regional version of the firmware. First, you need to start the standard Camera application and switch to the appropriate mode.

Usually, Portrait is a separate category in the bottom menu or is available via swipe on the screen in photo mode. In some versions of the interface, it may be called Portrait or designated by an icon with a human silhouette. Once switched, the camera will automatically analyze the scene and search for faces or objects to focus on.

Here are the main steps to activate:

• 📸 Launch the Camera app on the home screen or via a widget.
• 🔄 Swipe your finger over the bottom panel of modes left or right until you find the item "Portrait".
• 👤 Point the camera at the object; the system should illuminate the face or object with a yellow frame, confirming the activation of the mode.
• ⚙️ Click on the setting icon (often looks like three dots or a slider) to manually adjust bokeh settings.

It is important to note that portrait mode often lacks zoom or is limited to digital zoom unless the smartphone has a separate telephoto lens. Using the main wide-angle module can cause facial proportions to be distorted when shooting up close, so try to keep your distance around 1-1.5 meters.

Adjustment of the degree of blur and diaphragm

One of the key features of the Xiaomi camera is the ability to adjust the background blur force, which is often denoted as “Bokeh Effect”, “Aperture” or simply displayed by a slider with numerical values (for example, f/0.95 – f/16).

At f/0.95 or f/1.4, the blur will be maximum, ideal for singles or close-ups where you need to completely hide background details. Values like f/5.6 or f/8 give a lighter effect, maintaining the awareness of the surroundings, which often looks more natural for group portraits or reporting.

To set up, perform the following actions:

• 🎛️ In Portrait mode, find the icon in the form of aperture or slider at the top of the screen.
• 📉 Move the slider left or right, watching the change in the degree of blur in the viewfinder in real time.
• 📸 Take a test shot and evaluate the result, if necessary, adjusting the aperture value.

It is worth remembering that excessive blurring (values close to f/0.95) on digital cameras can look unnatural, creating a “cut-out application” effect. The optimal value for most scenes is the range from f/2.0 to f/4.0, which balances between artistic effect and realism of the picture.

Using Artificial Intelligence and Scenes

Modern Xiaomi smartphones are actively using neural networks to improve the quality of portraits. AI Camera (often indicated by a color icon in the upper corner) automatically recognizes a scene: a person, an animal, a flower or a document. In portrait mode, AI can further improve skin color, smooth textures and adjust lighting.

Some models have Studio Lighting mode, which mimics the work of professional lighting fixtures, which can artificially darken the background, add counterlight or change color temperature, creating dramatic effects without additional equipment, settings often found in the filter menu or special effects inside the portrait mode.

In difficult lighting conditions, such as counterlight or mixed-light spaces, AI can misbalance white, and in such cases it is better to turn off AI and adjust the settings manually, or use Pro mode if it supports aperture simulation.

Object shooting and macro shooting with bokeh

Xiaomi's portrait mode isn't just for people, but it works with objects, animals and even plants, allowing you to create beautiful subject photos for catalogs or social networks. The camera needs to clearly define the contour of the object, so the background needs to be contrasted.

When shooting objects (food photos, goods), it is important to keep your distance. The camera must be at the optimal distance for autofocus to work and build a depth map. If you get too close, you will turn on macro mode, which on many models does not support software bokeh, as the focal length becomes too small to calculate depth.

⚠️ Note: When shooting transparent objects (glasses, bottles) or objects with a complex structure (network fabrics, tree leaves), the bokeh mode may not work correctly.

To improve the result when shooting subject use a tripod or wrap your phone on a stationary object. This will eliminate lubrication, which with strong blurring of the background may be imperceptible, but at the edges of the object will create a "porridge" of pixels.

Bokeh editing after filming

One of the main advantages of the bokeh photo format on Xiaomi is the ability to post-process. Smartphones store information about the depth of the scene separately from the image itself (in metadata or an additional channel), which allows you to change the focus and degree of blur after the frame is taken.

To edit the effect, open a photo in the standard Xiaomi gallery. If the picture is taken in portrait mode, you will see an editing icon (often looks like a slider or aperture icon).

• 🔍 Change the focus point by selecting another object in the photo.
• 🌫️ Adjust the background blur force by moving the diaphragm slider.
• 💡 Change the lighting (if studio lighting was used).
• ❌ Completely disable the bokeh effect, returning the photo to its original state.

This feature is especially useful if you didn’t have time to adjust the perfect balance at the time of shooting, or if autofocus was mistaken and focused on the background instead of the face, but it is worth considering that a radical change in focus on the finished picture can lead to the appearance of artifacts, since the algorithm recalculates the blur based on the available data.

💡

Always save the original photo in Portrait mode without using filters to be able to edit bokeh flexibly in the future.

Frequent problems and ways to solve them

Despite the advanced algorithms, users can experience typical problems when using bokeh mode, one of the most common being the shaking or floating of the object's boundaries when the camera moves, due to a delay in building a depth map and the stabiliser.

Another common problem is unnatural foreground blurring: If you hold the phone too close to your face, the nose or ears can blur more than the eyes. The solution is simple: step back and use optical zoom (2x) if you have one, or just crop the photo later.

Comparison of typical errors:

If the camera doesn’t see the portrait mode at all or the button is inactive, check if the lens is covered with a cover or a finger. Also, in some models, portrait mode is not available when the flash is on or in certain video resolutions.
