How to shoot with long exposure on Xiaomi Redmi

Mobile photography has long since ceased to be just a way to capture a moment quickly, becoming a full-fledged tool for creativity. Owners of Xiaomi and Redmi smartphones often underestimate the capabilities of their cameras, relying solely on automatic “AI Cam” mode. However, hiding behind the simplicity of the interface, these devices have a powerful potential for creating professional images, especially in low light conditions.

Shutter speed photography, or long exposure, captures the movement of time: turn current cars into light streams, make water as smooth as glass, or capture star tracks. This technique doesn't always require expensive equipment, it's enough to adjust the matrix and shutter parameters of your gadget correctly. The key here is the manual control of exposure, which is available in a standard camera app.

In this article, we will discuss in detail the technical aspects of creating such images on Redmi Note devices and Xiaomi flagship series. You will learn how to avoid common mistakes such as digital noise or lubricating static objects, and what additional accessories will help you achieve a level of performance. DSLR-Understanding the physics of the process will allow you to turn any landscape into a work of art.

Principles of operation of shutter speed in mobile photography

To effectively control the process of shooting, you need to understand the basic mechanics. Shutter speed is the length of time that the camera matrix is illuminated by light passing through the lens. Unlike the human eye, which adapts continuously, the sensor captures the image only in a given time interval. The longer this interval, the more light it has time to get to the sensor, but the more blurred moving objects.

In automatic mode, Xiaomi’s smartphone aims to make the frame clear by setting a short shutter speed of, say, 1/60 of a second or 1/120 of a second. This is ideal for daytime shooting, but catastrophically small for night scenes. By switching to manual mode, you take responsibility for the balance between light and sharpness. Long shutter speed allows the matrix to accumulate enough photons even in low street light.

But there's a big risk here: any hand shaking will blur the entire frame, and if you normally lubricate only a moving object, long exposures will lubricate the entire image, which is why the stability of the device becomes critical. Without a hard lock, you can't use shutter speeds longer than 1/30 of a second.

• 📸 Short exposure (1/500 Second or shorter: Freezes fast movements, but requires a lot of light.
• ⏳ Long exposure (1 second or longer) blurs the movement, creating the effect of dynamics or smoothness.
• 💡 The balance of exposure is achieved by a combination of exposure, value ISO and diaphragm (if it is adjustable).

Importantly, mobile arrays are smaller in size than professional cameras, making them more sensitive to noise during long-term light harvesting. Current image processing algorithms in Snapdragon and MediaTek processors partially compensate for this, but the physical nature of the process has not been canceled. Understanding these limitations will help you realistically evaluate the result before you hit the down button.

Preparation of equipment and stabilization

Before you start setting up, you need to ensure that your smartphone is physically still, and that's the foundation of night and landscape photography. Even microscopic finger shaking, which is invisible in everyday life, will turn into a lot of blur when you shut down a few seconds. The built-in optical stabilization (OIS) systems that many Xiaomi models have are equipped with, only partially help and do not replace the tripod.

The ideal solution is to use a compact tripod with universal clamp for smartphones. If you don't have a tripod at hand, you can point the device against a stationary object: a stone, a parapet, a stack of books or a bag of sand. The main thing is to exclude any contact with the device at the time of exposure. In emergency cases, you can use a self-trip timer to prevent the shaking of the body when you touch the screen.

⚠️ Attention: Using digital zoom when shooting with long exposure is strongly discouraged. Digital zoom sprinkles the image, amplifying the noise and making any micro-vibrations of the camera noticeable even to the naked eye. Use only optical zoom or the main lens.

Also, it's worth taking care of the cleanliness of the optics. In nighttime shooting, the glare from streetlights on greasy spots, lenses can spoil the frame, creating unnecessary artifacts and reducing contrast. Wash the lens with a soft cloth before you start work. Also, if you shoot during the cold season, avoid extreme temperature changes that can cause the lenses to fog inside the case.

Setting up the Pro mode (Manual Mode)

To control shutter speed on Redmi and Xiaomi smartphones, you need to switch to Pro (Manual) mode. In the standard camera interface, it is usually located in the bottom menu of the swipe to the left or in the drop-down mode list, which opens up full control over shooting parameters, hidden from the user in automatic scenarios.

First, look for a setting marked with the letter S (Shutter) or stopwatch icon. When you click on it, you will see a scale that allows you to change the exposure time. The range of values depends on the model of your device: budget Redmis can be limited to 1/4 or 1/2 seconds, while flagships of the Xiaomi Mi or Xiaomi 13/14 series allow you to set shutter speeds up to 32 seconds and even higher in Night mode.

In parallel with shutter speed, you need to control the ISO setting (sensitivity of the sensor). For long shutter speeds, try to keep the ISO at a minimum value (usually 50 or 100), which will ensure maximum image quality without digital noise. Since the shutter speed is long, the light will suffice for the matrix at low sensitivity. In this case, raising the ISO will only add grain and reduce the dynamic range.

Focus is also better translated into manual MF (Manual Focus) mode. Autofocus in the dark can work incorrectly, "walking" back and forth. By moving the focus slider to the extreme position (mountain icon), you will fix the focus on infinity, which is ideal for landscapes and city panoramas. If the subject is close, carefully move the slider until a clear image appears at the preview.

Technique of shooting light traces and waterfalls

One of the most spectacular techniques is to capture the light trails from cars. To do this, find a hill next to a busy highway. Set shutter speeds in the range of 2 to 10 seconds. Cars whizzing past will turn into continuous lines of red and white light. The longer the shutter speed, the longer the tracks will be, but it's important not to overdo it so that they don't cover the entire frame.

Water photography is another classic genre: Falling waterfalls or sea waves, when exposed in 1-2 seconds, become like shreds of mist or silk, which is achieved by averaging the position of water droplets over the exposure time. The static rocks and shore will remain sharp, creating a beautiful contrast with the blurred water element.

When you're shooting moving water or transport, experiment with different values. There's no universal setting for all situations. Take a series of frames in 1-2 seconds to later choose the best option. Digital photography allows you to do this for free, unlike the film age.

Use of the “Night” mode for long exposure

The Night Mode, which is essentially a software implementation of long shutter speed with multiple additions, is worth noting. Unlike the manual Pro mode, where one long frame is taken, the smartphone makes a series of short exposures with different brightness levels and then combines them with HDR algorithms.

The advantage of Night mode is that it often gives a cleaner picture with less noise than one long frame in Pro mode. However, it has limitations: it does less well with moving objects (ghosts or blurs may appear) and gives less creative control over the lubrication effect. If your goal is a clear nightscape, use Night. If you need light tracks, go to Pro.
