Xiaomi's mobile phone comes with a key to change the sky.

This function of Xiaomi CC9 is quite hidden: after the user takes a picture, he first enters the photo album to play it, and then selects Edit-Filter-Change Sky, and then he can see seven different types of built-in sky filters. I noticed that each filter can also choose the intensity of rendering independently, and the default is 50%.

Then, let me take a photo taken with Xiaomi CC9 just this morning as an example. Although the weather in Shanghai is fine this morning, the sky in the photo still looks a little white and the clouds are not obvious. So, I first used the sunshine filter to see the effect, and adjusted the intensity to 8 1% by the way.

At this time, the color of the sky in the picture has changed obviously: the original gray sky has turned blue, and the shape of the clouds in the original sky has also changed. It is worth noting that this weather change function well distinguishes the boundary between heaven and earth-there is no obvious hook-shaped phenomenon on the edge of the building, and there are no jagged defects. Let me change two more filters and see what it will look like to turn the scene taken during the day into "dusk" or "sunset"

At this time, I adjusted the two filters to the highest intensity. It seems that the accuracy of Xiaomi CC9 in recognizing the sky is still quite high. And with the application of different sky filters, the color and brightness of the whole picture have also changed! If I don't tell you in advance that this is the function of the post-filter, I believe most viewers can't see through it, which is the result of "changing the sky with one key".

In addition to changing the sky for photos taken by the mobile phone itself, we can also change the sky for photos taken by third-party cameras by importing external photos into the mobile phone. For example, @pure is a panoramic photo of Lujiazui taken by my colleague @ purewhite box, and its own sky cloud system looks beautiful. But I can still make its blue sky and white clouds more eye-catching through "changing the sky with one key".

Or, what about the effect of turning this photo into a "sunset"? However, at this time, we'd better change the title of the photo to "Sunrise in Lujiazui"-because from a geographical point of view, if this photo is named "Sunset in Lujiazui", it will really become "The sun rises in the west"! (Laughter)

In order to verify the accuracy of Xiaomi CC9' s built-in "change the sky" function for sky contour recognition, I asked @ purewhite box for this photo with a window frame. If the mobile phone can't correctly identify the scenery of the sky and the ground, or just sketch the edge of the picture, and then cut the picture, then the blurred foreground window frame edge will appear defects. But in fact, I am very satisfied with the performance of Xiaomi CC9. The "changing weather" of this photo is seamless, and it is really difficult to find any flaws in post-processing. ...

Of course, not all pictures are suitable for "changing the weather": for example, this real Lujiazui sunrise scene, because the building has been dyed golden yellow by the sun, so there is no objection to adding a "sunset" filter to it;

Sunset, a sunny day

However, if it is forced to be replaced by "clear" blue sky and white clouds, the contrast between the color of the sky and the color of the ground building will be unnatural and look a bit fake. In addition, I heard from my colleagues that they also intend to use sky maps and hand-painted scenes to test the "changing weather" function of Xiaomi CC9. I don't know if the new machine can successfully pass such a severe test, let's wait and see the test results ~
