How to set the camera software that comes with the mobile phone so that the picture of the lens moves with the movement of the lens when taking pictures?

Some simple functions of mobile phones are often overlooked by us, such as focusing and metering functions in cameras. If you use it well, you can easily shoot a large piece of texture. If it doesn't work, it will waste a lot of pieces!

Today, Bian Xiao will talk to you about the focusing and metering functions in the mobile phone camera.

Under normal circumstances, when the phone opens the camera interface, it is in auto-focus mode, and the focus and metering points are linked, and the camera will adjust the exposure of the picture according to the choice of focus.

Let's take an example to see the difference between autofocus and mobile phone focusing.

▼ autofocus

▼ Manual focus

As can be seen from the above two samples, the photos taken by autofocus lack hierarchy and the priority is not clear; The following picture uses manual focusing, which makes the foreground clearer, the background blurred and the picture more orderly.

So, don't forget to choose the right focus when taking pictures with your mobile phone. So the question is, how should we use the focus/exposure function to take some different photos?

1. By adjusting the exposure to the focus

After mobile phone photography entered the "algorithm era", various AI smart camera modes were introduced, which is essentially no different from the "fool mode", that is, the camera was handed over to the mobile phone kernel for processing.

Although it is easier to take pictures after the camera is intelligent, most photos still lack originality. Mr. Lu Xun once said that "photography is the art of using light". Therefore, to learn photography, we must first learn to control light.

In professional photography, the photographer will control the exposure by adjusting the aperture, ISO and shutter. But these are a little complicated for many beginners of photography.

Then, in our mobile phone photography, can we control the exposure in some convenient ways?

Answer: Yes!

Is today shooting day after school?

Yes, control the sun!

But it's not shooting at the sun. We are taking pictures and controlling the little sun.

Tap the screen when taking pictures, and a small sun sign will appear next to the focus. Choose the appropriate focal length, slide the small sun up and down, and the brightness of the photo background can be determined by yourself.

Even in indoor shopping malls during the day, clicking on the focus and sliding down at the same time can reduce exposure and take different silhouette photos.

In addition to directly dragging the small sun, there is another way to adjust the exposure, that is, to separate the focus from the metering point. Both Huawei and Nubian mobile phones have this small function.

After selecting the focus point, press "Focus Point" again to drag out the metering point separately, and put it in the "middle tone" position of the screen to measure light, keeping the focus point unchanged.

This focusing method can not only ensure the clear outline of the subject, but also adjust the exposure of the whole picture according to the brightness of the middle tone, and keep as many details as possible. For example, the following two situations:

Two. Choice of focus

When shooting a sunset silhouette, we often encounter two problems: is focusing to choose a darker subject to make the outline of the subject clear? Or choose bright areas to ensure bright details? Let me tell you three ways.

1 The focus is on the subject.

The picture below shows the author Ryan. At that time, he chose to focus on the bird and then fine-tune the exposure.

The background of this photo is relatively simple, and there is no particularly bright highlight area, so choosing to focus on the subject at this time can make the outline of the subject clearer.

2 Late adjustment

If the exposure is minimized and the desired effect is still not achieved, it can only be post-processed.

Let's take a look at this work "Umbrella". The author's focus is also on umbrellas in the dark. Later, MIX was used to improve the contrast of the photo and make the whole photo more layered.

So should all silhouette photos focus on the subject in the dark?

3. Select the middle focus.

In the photo below, the sunlight on the right is brighter. If the focus is still on the characters at this time, the sky will explode. Choosing the brightest area of the sun, the foreground is too dark, so the author chooses the flame cloud near the sun, that is, the "middle tone".

You are the most beautiful sun on the horizon ▼

This kind of focusing method will be used more when shooting silhouettes. Intermediate focusing will neither overexpose the highlights nor darken the dark parts, so that there is more room for adjustment later.

Therefore, the focus is not completely absolute, and you need to judge your focus according to the light on the spot.

Three. Exposure locking

The focus/exposure mode includes focus metering linkage and focus metering separation, as well as lock focus/exposure mode.

When we shoot close-ups of flowers, if the focus is not locked, there is wind or the camera moves, the camera will default to the previous focus failure. It will reselect the focus and readjust the exposure.

Unlocked state ▼

At this time, if you don't want the camera to do this, then you need to press and hold the focus of the screen to lock "auto focus/auto exposure", and then no matter how we move, the focus of the phone will not change.

Lock focus/exposure ▼

This function will be very practical when shooting some insect works. Choose the right focus, adjust the exposure, and wait for the insects to enter the painting.

What are the new ways to play exposure locking?

1, water drop, light spot

On rainy days, I want to shoot water droplets at close range through the window glass, but it is difficult to focus on them.

We can put our hands close to the lens, select the focus point at the fingertips, and press and hold the focus point to lock the focus/exposure, so that the focal length of the camera is fixed. At this time, we can shoot water droplets near the window.

In the same way, you can also use this trick to shoot night scenes.

Step 2 shoot continuously

Focus on the person's head, lock the focus/exposure, and press and hold the shutter button to take multiple photos continuously in coordination with the action of the model.

Finally, I leave a question for you: How do you think the author of the following photo chose the right focus and adjusted the exposure? You can express your opinions and suggestions in the comment area!
