Owners of Xiaomi, Redmi and POCO smartphones often face situations where automatic camera settings can’t cope with difficult lighting conditions, instead of a clear frame, a blurred spot or, conversely, a too dark image, occurs because automatic shutter speed tries to compensate for the lack of light by prolonging the exposure time, which leads to lubrication of objects at the slightest movement.
Understanding how this works makes it a powerful tool for creativity, and taking the shutter speed away from the context of mobile photography is taking control of AI and setting fixed values that you want, and in standard mode, the system decides how long the matrix will take to collect light, but in manual mode, these constraints are removed.
You don't need any third-party apps to get started, because the built-in MIUI Camera or HyperOS Camera software has a lot of functionality, but many users don't know where these settings are hidden, taking the standard interface as the only option. Next, we'll look at a step-by-step algorithm that allows you to fully control the shooting process.
What is shutter speed and why should it be regulated
Shutter Speed is the time it takes for light to hit the camera matrix. In automatic mode, Xiaomi's smartphone analyzes the scene: if it's dark, it lengthens the shutter speed so that the photo isn't black. If there's a lot of light, it shortens it so that the frame isn't over-lit. The problem is that long exposure often leads to motion blur, especially if you're shooting with your hands or moving objects.
Adjusting this setting is necessary in several scenarios, for example, when shooting sports or children, you need to freeze movement by setting a short exposure time. In night photography, on the contrary, long exposure is necessary to create the effect of light trails from cars, but the phone must be fixed on a tripod, Understanding this dependence is the key to quality pictures.
- 📸 Short exposure (1/1000 C and shorter) freezes fast movements but requires a lot of light.
- 🌌 Long exposure (1/10 c and longer) lets more light through, but lubricates movement without a tripod.
- ⚖️ Balance between exposure and ISO It helps to avoid noise in the photo.
⚠️ Note: When installing long shutter speed manually (more than one) 1/30 seconds) it is highly recommended to use a tripod or stop, otherwise the trembling of the hands will make the frame fuzzy.
Xiaomi's standard camera algorithm often sacrifices detail for the sake of brightness. It can raise the ISO (matrix sensitivity) to celestial values, creating digital noise, or lengthen the shutter speed, creating "porridge" instead of texture. Manual setting allows you to decide whether the frame is clean or bright.
Transition to PRO mode for manual control
To access shutter speed control, you need to switch from the standard Photo mode to the PRO mode (Professional). In this mode, the camera stops making decisions for you and gives you full control of the exposure. The interface may vary slightly depending on the version of the MIUI or HyperOS shell, but the logic remains the same for all Xiaomi models.
Find the modes bar in the camera menu (usually at the top or bottom of the screen that says "Photo", "Video", "Portrait"). Flick to the right until you see PRO or Professional. In some firmware versions, this mode can be hidden in the More menu, which is indicated by three dots or a dotted square.
Once you activate the mode, you'll see a series of icons or sliders at the bottom of the screen, and we're interested in a parameter designated S (Shutter) or stopwatch icon, and that's where the main magic of setting exposure time happens, and by default, there might be an Auto value here, which you need to change.
💡
If you don’t see PRO mode, check the settings of the Camera application – in some regions or on older versions of the software, it must be activated in laboratory functions (Lab features).
The shutter speed setting interface is usually represented by a slider or a scroll wheel. When you move it, you change the denominator of the fraction. 1000 is 1/1000 of a second (very fast), and 2" is 2 seconds (very long). It is important to monitor the exposure indicator (EV), which shows whether the frame will be over- or under-exposed at the current settings.
Configuring exposure parameters and ISO
Shutter speed control is inextricably linked to adjusting the sensitivity of the matrix, or ISO. When you "remove" the automatic shutter speed by setting a fixed time, you often have to compensate for the change in the amount of light through ISO. If you reduce the shutter time (to stop movement), the frame will become darker, and you will have to raise the ISO.
In PRO mode, find the ISO icon. You can also select Auto or set a specific value. For daytime photography, the optimal values are 50 to 200. Indoors or in the evening, the values can rise to 800, 1600 or higher. However, remember: the higher the ISO, the more digital noise (grain) will appear in the photo.
| Screenplay of the shooting | Recommended excerpt | Recommended ISO | Need for a tripod |
|---|---|---|---|
| Sport/Children | 1/500 - 1/2000 s | Auto / 100-400 | No. |
| Portrait by day | 1/100 - 1/250 s | 50-100 | No. |
| Landscape (static) | 1/60 - 1/125 s | 50-200 | Preferably. |
| Nighttown | 1/10 - 2s | 50-100 | I'll be sure. |
| Light tracks | 5 - 30 s | 50 | I'll be sure. |
The balance between these two is the basis of exposure. If you put a short shutter speed, but ISO is at its maximum and the photo is still dark, then there is a physical lack of light, in which case you either have to accept the noise or look for additional lighting. Xiaomi algorithms in automatic mode often aggressively raise the ISO, so manually adjusting it gives a cleaner picture.
☑️ Checklist of exposure settings
Use of exposure fixer (AE Lock)
If you don't need a full manual PRO mode, but you want to record your current settings in normal mode, use the AE Lock (Auto Exposure Lock) function, which allows you to "remove" the constant spikes in brightness when you change the composition of the frame, and the camera will capture the light parameters that were at the time of locking.
To activate this feature in the standard Photo mode, tap the screen at the point where the object you want to capture is located. A yellow focus square will appear. A lock or sun icon may appear next to or inside it. Pressing this icon or holding the focus area for a long time will often activate the lock.
Xiaomi’s interface often has a brightness slider (sunshine) on it after tapping the screen to focus. If you pull it down or up, the camera will know you want to change the exposure, but it will still float when the lighting changes. For hard fixing in new versions of HyperOS, you can use third-party apps or scripts, since the standard AE Lock feature is not implemented explicitly in all models.
⚠️ Attention: Fixing the exposure (AE Lock doesn't turn off autofocus completely unless you switch to manual focus. The lens can keep looking for sharpness, changing the big picture even if the brightness is fixed.
Using AE Lock is useful when shooting contrasting scenes, such as when an object is in front of a bright window, you focus on the face, you capture the exposure, and the window does not "knock" the frame white while you frame the composition, it is a semi-automatic way of controlling, which is easier than full manual mode.
Capturing moving objects without lubrication
One of the main reasons users want to remove the shutter speed is to combat lubrication of children, animals or vehicles. In automatic mode, Xiaomi indoors often puts a shutter speed of about 1/30 or 1/15 of a second, which inevitably leads to a "wiggle." To avoid this, you need to force a value of less than 1/100 of a second.
Go into mode. PRO and set the shutter speed S to the value 250 (1/250 (c) or shorter. You will immediately see that the screen_preview_ It's going to get darker. ISO until the image is bright enough, if ISO 3200 It's still dark, so there's a critically low amount of light, and you either need to turn on the flash or get closer to the light source.
Why are the night photos of children lubricated?
Another important thing is the serial mode. In PRO mode, it's often unavailable, but in normal mode, you can press the down button. The camera will take a series of frames with different exposures and focus. In 10-20 shots, the probability of finding one clearer than in a single frame is higher, but this does not replace the correct shutter speed setting.
Long exposure for creative effects
Paradoxically, sometimes the shutter speed doesn't have to be "remove" (short), but instead, you have to lengthen it by hand for artistic purposes, shooting waterfalls to make water look like milk, or painting with light in the dark requires shutter speeds of 1 to 30 seconds. In automatic mode, Xiaomi will try to make the frame brighter, reducing time, so you need a PRO mode.
Set your phone on a tripod or point against a stationary object. In PRO, set the shutter speed to 2" (2 seconds) or use B (Bulb) mode if available in your model. In Bulb mode, the shutter is open while you hold your finger on the trigger button (or up to 30 seconds in some versions).
For such shots, it is critical to turn off stabilization if the phone is on a tripod, although in Xiaomi smartphones this often happens automatically when determining the immobility. It is also recommended to use a descent timer (clock icon) so that touching the screen does not cause vibration at the beginning of exposure.
💡
Long shutter speed allows you to capture the movement of time in one frame, turning the chaotic streams of people or machines into smooth, beautiful lines.
Frequent problems and their solution
You may encounter a number of challenges when you switch to manual control, like a photo that's too grainy, which means you've raised your ISO too much in an attempt to compensate for the short shutter speed, so you can find a compromise by extending the shutter speed a little bit, but not by getting to where the lubrication is.
Another problem is that the focus is not induced in PRO mode. Make sure that the MF (Manual Focus) setting is not twisted to its extreme position. It is best to put it in the Infinity position for landscapes or to twist the slider until the focus picking strips (green or red contours) appear on the object.
Sometimes users complain that after setting the settings, the photo still turns out different from the one on the screen. This is due to post-processing. Xiaomi applies improvement algorithms (HDR, noise reduction) after the frame is taken. To minimize interference, you can try turning off "Improving Photo" in the camera settings or shoot in RAW (DNG) format if your model supports this mode in PRO.
