It's a headache to shoot night scenes with mobile phones , Because the quality of the lens is not good enough , The pictures taken in many scenes are of poor quality , There's a lot of noise , But it's not that cell phones can't shoot night scenes , By choosing the right time 、 place , And proper prophase and later techniques , Some night scenes can be shot by mobile phone .

Another way is to use some auxiliary software or professional shooting function , With tripod this relatively complex way to let the mobile phone shoot some of the night scenes that can't be taken under normal circumstances , In this way, we may say later , Today I'm mainly talking about the solution to conventional shooting .

The best time to shoot a night scene is In the evening , That is to say 「 It's not quite dark yet , And the street lights around it are on At this point in time . The reason is that the light is much better than the pure night , The picture quality is better , And the surrounding street lights and sky color will have a good effect at this time .

In fact, I started to pay attention to this kind of time point only recently , So there are not many examples , Picture 1 was taken yesterday , And figure 23 shows me shooting VUE A clip of a small video ( So the picture quality is poor ). They were all shot in the evening .

Shoot at this time , Because the light can still , It's the same way you shoot during the day , It's a regular shot , Except for the subject , At the same time, pay attention to let the picture show the light at this time / The beauty of the sky .

Finally explain , It's just that the shooting will be better at this time , But it's not the only time to shoot . Our method may have nothing to do with shooting at this time .

The right place to shoot , In a nutshell : Where there is light . So that the quality of our photos will be better , It doesn't look like a lot of noise .

There are two ways of shooting where there is light : Shoot with light or with light . Generally speaking, the source of light is the lamp in front of you or the street lamp behind you . Let's take a look at the example .

See what I mean , It's to shoot something with light , I'll tell you how to shoot it later . The same thing about these scenes is that without their own lights , So just shooting with the light around at night , There is no doubt that there will be a lot of noise .

These are all scenes with lights behind them , And it's closer . Without these lights , The scene itself will be very dark , There will be a lot of noise in the picture , Maybe you can't see it at all .

Finally, what scenes can't be shot :

It is recommended not to shoot scenes that do not meet the above two conditions . Usually the situation that doesn't fit is that there is no light around 、 The light is too weak 、 The light is too far away , I'd like to talk about an example of being too far away : For example, we shoot objects with light , You photograph the brightly lit buildings on the other side of the river , There's probably a lot of noise , Because it's too far .

The purpose of the night scene shooting technique is simple , That's to make noise as little as possible , Let's look at it step by step .

If your phone is equipped with night scene optimization function , such as Smartisan Series of mobile phones , So open this first .

Try not to adjust the exposure at a later stage , That would damage the quality of the picture , It's fine during the day , The quality of the night picture is really a little bit careful . Generally, we adjust the exposure value to reduce the overall picture brightness , In this way, the automatic adjustment of mobile phone camera should be able to put ISO Lowers , The purity of the picture will be better , Of course, it may be to speed up the shutter first , In that case, it will be more difficult for us to paste , Which parameters will be adjusted first? I haven't measured , All in all, it's good , And even if the brightness of the image is reduced, the noise will be much less .

In addition, it depends on how your mobile phone handles the night scene , Most mobile phones are generally lighter , Can be lowered a little bit . If your phone is dark by default , Then you can turn it on a little bit , This avoids adjusting at a later stage , It's also good for picture quality .

The location of the touch here is usually where you want to shoot , Not the dark part of the picture . The dark part of the picture will be darker in this way , The highlights are brighter , Mainly to make the dark part darker , In this way, there will be less noise in the dark . You can refer to my front 「 The right place to shoot 」 An example of , It's all dark .

These three steps are mainly to solve the noise problem of night scene , The first step is the system software algorithm for noise reduction , The second step is to reduce the brightness of the image to reduce noise , The third step is to darken the dark part , Further reduce the brightness of unimportant images , Reduce the noise in the image .

In the later period, because of the space involved , I'd like to briefly say this time , We can introduce it in detail later on . Generally speaking, the post-processing of night scene photos has two purposes : Show the lights / The beauty of color , Reduce noise .

About 「 Show the lights / The beauty of color 」 It should be easier to understand , use VSCO Choose your favorite filter , Adjust the color temperature properly 、 tonal 、 Saturation will do , This is mainly about noise reduction .

Although it was said that the exposure should be controlled in the early stage of shooting as much as possible , But it is likely that we will have to fine tune later , Here the brightness is mainly fine tuned to the appropriate brightness , If you need to adjust the brightness of this image a lot , Then it's very likely that the picture will be destroyed .

It's usually recommended to add a little bit of contrast , It makes the whole picture look a little darker , We mainly want to make the dark part dark , In this way, the noise will disappear .

This I shared earlier and 「 Listen to it together 」 Li Curriculum , later stage 「 Spicy Hot Pot 」 That picture shows , The way is to erase all the unimportant parts of your photos , It's usually four weeks , You can download it by yourself Snapseed Try it , Here I give 「 Spicy Hot Pot 」 The picture is compared before and after revision , You can see that .

Right , still Snapseed , This time it's local function , Can be used for local brightness / Contrast / saturation / The structure is treated , We mainly use Local brightness + Contrast Handle , Make the dark part of the picture darker , So if there's a bit of noise in the dark , There will be no more noise . In my previous example, the dark part of the picture is pure black , Most of them are handled in this way .

that ... thank Snapseed , thank Google .

Here the specific photos are processed , Generally speaking, the structure can be adjusted to a negative value , In other words, some details of the picture will be lost , It makes the whole picture look smooth , The feeling of good picture quality . I'll give you an extreme contrast .( The entry point of structural function is 「 Highlight the details - structure 」)
