Reflections on a calm lake and water flowing like silk: you can capture exactly this look directly with your smartphone, without editing it on a computer later. With a DSLR, you have to set the exposure time, aperture, and ISO yourself and constantly double-check them. With many smartphones, on the other hand, a single extra function is enough. In the video at the lakeshore, Marko shows how he proceeds, which accessories he uses, and what he pays attention to when composing the image and during the waiting time. The following guide picks up this process and explains each step to you.

Key Takeaways
- Silky water is created by a long exposure time. For calm water, 30 to 40 seconds is usually enough.
- A stable stand, such as a Gorillapod, and a Bluetooth shutter release prevent camera shake.
- You should lock focus and exposure before starting so that the image does not change during the recording.
- A horizon placed in the center and a sparingly used foreground ensure a clear, calm composition.
- A reference point such as a stone in the water makes the movement of the water more visible in the result.
Step-by-Step Guide
1. Choose the subject and location
Look for a place where the water lies calm and reflections form. Lakes, rivers, or puddles are particularly well suited, especially under a cloudy sky, since the even cloud cover keeps the light soft. Pay attention to whether wind is creating small waves. These can hardly be removed later and become distracting as soon as you look at the details. The silky water function is designed precisely to render water more softly. However, the location has the greatest influence on the result.
2. Secure the smartphone firmly
A long exposure does not forgive any movement. Therefore, mount your smartphone on a Gorillapod, which Marko has clamped to a bench. Alternatively, a tripod, a railing, or a wall will work. It is important that the device remains unchanged throughout the entire exposure. Even small vibrations from footsteps or wind have a clear effect on sharpness at 30 seconds.
3. Activate the light painting app and the silky water mode
Open the app on your smartphone that Marko calls light painting. There you will find several sub-functions. Select the silky water mode. The principle is similar to a classic long exposure with an ND filter on the camera: the movement of the waves is blurred over time, while calm areas stay sharp. The function takes care of the manual values for you.
4. Determine the composition
Position the smartphone so that the horizon is roughly in the center of the image and the sky and water share the area about equally. In the video, it is a stretch of forest on the shore that forms this dividing line. The dark trees add extra detail to the water and sky. For your first attempt, do without a strong foreground. A classic, minimalist composition often looks calmer with silky water. Otherwise, small gusts of wind quickly create blurry areas in the foreground.
5. Lock focus and exposure
Tap on the display at the spot that should be sharp; in the video, this is the center of the subject. Then you lock focus and exposure. Marko makes sure the focus is exactly right before continuing. The lock prevents the camera from readjusting during the long recording and the brightness from changing due to shifting light conditions.
6. Avoid camera shake with a Bluetooth shutter release
So that you don't touch the display, Marko uses a small Bluetooth remote shutter release, which he ordered on eBay for a few euros. Connect it to the smartphone beforehand and test the connection at home. At the lake, you then start the recording using the button on the release. This keeps the device still, and that is exactly what matters.
7. Choose the exposure time and wait for the result
Once the shot is running, the live image changes: it first becomes darker or brighter, and the water looks increasingly smooth over time. Marko exposed for about 40 seconds. The longer the smartphone records, the smoother the water becomes. For calm water, 30 to 40 seconds is usually enough. For a waterfall or more turbulent water, you should allow a bit more time. The display reflects strongly in bright light, which makes the live image hard to judge. In this phase, trust the correct center and the locked settings.
8. Change your position and enhance the milky effect
If the water doesn't look soft enough yet, go lower with the smartphone. This way, Marko finds a position where the water takes up a larger part of the image and appears more milky. Make sure that no branches or blades of grass protrude into the frame, as they could disturb the impression. Repeat the test after every change of position until you have found the right spot.
9. Plan a second attempt with a reference point
For another attempt, Marko chooses a different section with a bit more foreground and detail. There is a small stone in the water that illustrates the movement of the water well. Such reference points help with image composition because the eye uses them as anchors. Grids or lines in the image also support the composition, especially if you haven't been photographing for long.
10. Remove distracting image elements and start the exposure
Check the frame before you start the shot. In the video, an element in the upper right area is distracting. Marko doesn't crop it out and instead shifts the frame slightly to the side. Then you start the exposure again with the shutter button. In this run as well, 30 seconds elapse before the result is available.
11. Evaluate the result correctly
When the time is up, a signal tone sounds and you can open the image. Assess it calmly on a larger screen, if possible. In the video, the waves are still slightly visible, but overall the water looks significantly calmer. Grasses that moved during the exposure are blurred, while the stone and the rest of the water area look sharp. This blur is not a mistake, but shows the movement in the image. If you aren't satisfied with the result, repeat the attempt from a different position or with a slightly longer exposure time.
Summary – Photographing silky water with a smartphone: Step by step
With a long exposure time, a stable stand, and a Bluetooth remote shutter, you get silky water straight out of the camera. Aim for a calm composition with a centered horizon, lock focus and exposure before starting, and plan for 30 to 40 seconds. Try out different positions, because often the position decides the result more than any setting.
FAQ
How long should I expose for silky water?For calm water, 30 to 40 seconds is usually enough. For waterfalls or strongly moving water, it can take a bit longer for the water to look smooth.
Do I absolutely need a tripod?Yes, a tripod or another firm support is very important, since any movement during the exposure becomes visible as blur. A small Gorillapod is already enough.
Why should I lock focus and exposure?So that the camera doesn't change its settings during the long shot and the image stays evenly exposed.
Why are some areas blurred in the result?Grasses or twigs that move during the exposure are rendered blurred. This shows the movement in the image and is not a mistake.
