How to set up Huawei mate9 photography function?

Exposure value: The combination of shutter speed value and aperture value is used to represent the light passing ability of the photographic lens.

Exposure is usually represented by the combination of shutter speed (t) and aperture value (f). For simplicity, it used to be expressed by light value (LV), but now it is expressed by EV. EV is the abbreviation of English Exposure Values, and it is a quantity that reflects the degree of exposure. Initially defined as: when the sensitivity is ISO 100, the aperture coefficient is F 1, and the exposure time is 1 s, the exposure is defined as 0, the exposure is reduced by one step (the shutter time is halved or the aperture is reduced by one step), and the EV value is increased by 1.

Calculation of EV value: Assuming that the aperture value is set as f and the shutter speed is t, there is the following relationship: EV = 3.322 log 10(f×f/T) Every time the exposure value increases 1, the exposure will change by one step, that is, the exposure amount will be halved, for example, the exposure time or aperture area will be halved.

You can adjust the resolution of the camera by setting it in the camera. If it doesn't respond, will you turn on the camera's large aperture mode? If you turn on some special camera modes, it may be used. Then I want to say that you really don't understand. I don't need to explain here. As we all know, with Leica dual cameras, you can take photos that others can't. I used to use P9 plus, but many friends who took photos around me have switched to P9 series phones, and I can still shoot big movies. In their hands, the photos taken by P9 are simply beautiful. Mate9 did not hesitate to start after it came out. Although it took nearly 30 days from booking to receiving goods, it was still full of surprises.

There is such a question, that is, Xiaobai, who just started mate9, why the photos taken are not as good as advertised. In fact, it's not the mobile phone, but the lack of systematic understanding of photography. When traveling, it is beautiful to stand in a small flower. It's not called photography if you shoot casually ... there are many examples of this. In fact, photography is emotional, just a picture, and what you want to express is very important. Determine the theme to express, and then the composition, composition is how to make your theme express in a more perfect form. This is not difficult to understand, is it? It's one thing to shoot, and sometimes it's nice to change the composition. Like this.

It's sunny. I'm going to take a picture of this landscape plant on the roadside, and then take a picture casually. It doesn't look very effective, but what if I change my angle?

From another angle, because the subject is brightly colored and the distance is less than 2 meters, will there be unexpected effects with a large aperture?

Photo preparation: mate9?

There is a theory in photography called photographic eye, that is, no matter what you see, your first feeling is to decompose the scene in front of you, and then judge how to shoot the scene in front of you better. The photographic eye is an observation ability, which can see what can be photographed. The same scene, if you look at it with your heart, will be different from what others see. It's your uniqueness to shoot the scenes you see in your heart.

When I meet something that can be photographed, I will think, if you photograph the scene in front of you, how would you photograph it? How can we find a distinctive way of writing that is different from others? Of course, this requires creativity. Some people say that the best composition is to break the way of composition. I may belong to this kind of person. However, the composition standard should not be easily broken, because this is summed up by the predecessors in the photography industry, and we should cultivate our own composition ability in the early stage. That is, shoot what you want to shoot according to specific composition standards.

The reason for publishing this tutorial is very simple, that is, let everyone thoroughly play mate9' s Leica dual camera. In addition, because everyone is not a master photographer, just sharing photos, don't mind if you don't shoot well. The photos in this article are mainly for illustration. Please forgive me.

If you want to take good-looking photos, tell us your mobile phone: mate9. Know yourself and know yourself, and you will win every battle. If you don't know your mobile phone, you can't use a gun on the battlefield. So what are the mysteries of mate9' s camera? Listen to me.

1, Leica mode.

The so-called Leica mode is divided into two levels, bright mode and soft mode. Generally, I switch to bright mode, and the color of the photos taken in bright mode is extremely pleasing to the eye, which is the biggest highlight of this camera. Leica-style photos have a German flavor and are called German poison.

Summon mode: Click on the colored square at the top of the camera interface and select the bright mode.

Many friends ask you how the Leica watermark in the lower left corner of the photo came from. It's actually quite simple. Just left-click on the camera interface, bring up the settings and select Leica Watermark. I have reservations about whether photos should be watermarked.

I have to say that mate9' s camera settings are really rich, and all the parameters are similar to those of SLR, so will you really use these camera modes? Slide from left to right, and a page full of photo modes will appear, including black-and-white camera, skin-beautifying camera, panorama, night scene, streamer shutter, video, HDR, skin-beautifying video, time-lapse photography, slow motion, watermark, audio photos and downloading various modes, just like opening a treasure chest.

Black and white camera: suitable for human photography, street shooting, architecture, ancient towns, hutongs and so on. It is also suitable for shooting scenes with strong contrast between light and dark. Leica's black and white is not simply to eliminate color, but to polish black and white.

Super night scene and streamer shutter: In fact, these two modes are both analog camera long exposure. By stabilizing the mobile phone, with the increase of time, photos with different effects are taken.

Super night scene and streamer shutter mode must keep the phone stable, so a tripod is essential.

This picture is taken at night in automatic mode, and we can see it.

This picture is a super night shot:

It can be seen that the scenery taken in the super night scene mode is more transparent and beautiful, and the vague reflection on the water shows that it was formed by long-term exposure. So, if you like to record the night scenes of big cities, you must try super night scenes.

Similarly, the streamer shutter also has four long exposure modes, namely, traffic, brilliant graffiti, gorgeous star track and silk flowing water.

Similarly, everyone needs to stabilize the phone, and the slight shaking of the phone will make the picture paste.

The traffic is the traffic at night. Standing on a tall building, you can get a panoramic view of the whole city, so it is best to shoot the traffic at this time. Because of the limited conditions, this picture is only for display. The lines in the picture are traces of vehicles passing by.

Brilliant graffiti, gorgeous star track and flowing water, because I didn't have a chance to shoot outside, I found the one I took with other mobile phones before. Note that when shooting the orbit of a star, you must find the reference object. Composition is very important. I only took it for introduction. Light painting graffiti:

Silk flowing water:

Gorgeous star track: (this one is not gorgeous) The star track must be shot in a dark place, and no stray light can enter the lens.

The second thing to say is mate9' s photo pro. The so-called professional model. Professional mode comes from SLR cameras. Many bar friends are discouraged from the professional mode. In fact, mastering these points, any professional model is a piece of cake. Open mode. Click the pro button at the bottom of the camera interface to open the professional mode.

Understand professional camera parameters

1: measurement mode

There are three metering modes, namely matrix metering and central button metering (from left to right).

Matrix photometry: The camera will automatically divide the viewfinder into several photometry areas. After measuring each area with an independent photometer, the obtained exposure value is averaged in the camera to obtain the total average value. The main purpose is to get the correct exposure of the whole picture.

Center focus photometry: it is a traditional photometry method, focusing on about 2/3 of the center of the picture. The advantage of this metering method is that it is easier to control the effect.

Spot metering: It is mainly used to measure light in the area where the center of the picture is very small or even a point, which accounts for about 2.5% of the width of the picture. The metering and exposure value in this area are very accurate. The disadvantage is that if bright spots are detected, most areas will be underexposed, while if dark spots are detected, more positions will be overexposed. Therefore, the selection of metering points is very important when using spot metering mode for metering.

You look scared, don't you? I'm sure nobody understands. What the hell is photometry? Generally speaking, spot metering is to partial metering the center point or other focus points in the picture, regardless of whether other areas of the picture are exposed accurately. Central key photometry is to measure the whole map in different regions and then average it. The simple understanding is that photometry is responsible for the light and shade distribution of the whole photo, and the central focus is on photometry, so that the photo is even in light and shade. Spot metering is more suitable for shooting actors on the stage, that is, taking the actors as the metering point, and the photos taken are based on the brightness of the actors, not the shady scenes around the actors.

If you understand, please leave a message. In short, I usually don't adjust this, and the default button metering is no problem, because I rarely encounter special scenes.

2. Shutter time and sensitivity

S stands for shutter time: the larger the denominator, the clearer it is, and the smaller the denominator, the trajectory is connected into a line. In other words, the larger the denominator, the shorter the shutter time and the faster the photo is taken. However, due to the high speed of the camera, the light may be insufficient and the picture will appear very dark. The bigger the denominator, the later it becomes 1, 2,3, which means that the shutter time is 1 second, 2 seconds, 3 seconds, and the photo taking time becomes slower and slower, which will make the photo shine and even explode. In fact, long exposure is to adjust the shutter time as long as possible, which is suitable for shooting night scenes. Remember to use a tripod. I like super night scenes, and I got a ready-made button for you directly based on this.

ISO table sensitivity: The smaller the number, the lower the sensitivity, and vice versa. The picture with low sensitivity is clear, and the picture with high sensitivity has more noise. Generally, cameras shoot night scenes without tripods. In order to ensure that the photos are not pasted, it is necessary to lock the high-speed shutter. According to the introduction of shutter, high-speed shutter will lead to insufficient light and the photos taken are very dark. At this time, increasing the sensitivity can brighten the picture. You can test it. But this will sacrifice the image quality. I suggest that when you learn some professional models, you should do more on-site operations and make more comparisons.

Let's share with you several corresponding scenes with shutter time suitable for shooting (camera scenes are also suitable for mobile phones):

1/ 1000 seconds or more: it is suitable for fast-shooting sports with telephoto, such as airplane take-off,1000-meter race and other high-speed sports.

1/250 seconds: suitable for shooting sports with average speed, such as shooting people to run 500 meters and breaststroke.

1/60seconds: It is difficult to shoot by hand, easy to shake, difficult to keep stable, and only used in poor light.

1/ 15 seconds or less: it is recommended to use a fixed tripod to set up the camera for shooting, otherwise it is very easy to shake, and novices generally recommend using a tripod to stabilize it.

3. Exposure compensation

EV stands for exposure compensation, that is, if you think the picture is bright, it will decrease the value, and if it is dark, it will increase the value. This is the same as the sliding adjustment of brightness in the camera focusing interface. It is also the most commonly used.

Sometimes the photos are too dark or overexposed. At this time, exposure compensation can be used to correct exposure. The basic operation is as follows: If the taken photos are too dark, increase the exposure compensation value (+EV), and if the taken photos are overexposed, decrease the exposure compensation value (-EV).

4: Focus mode (AF)

The autofocus mode supports automatic single focusing, automatic continuous focusing and manual focusing. The default is automatic continuous focusing. In auto continuous focus mode, press and hold the icon to unlock the focus lock.

Automatic single focus (AF-S): It is suitable for shooting static subjects or scenes with small motion range.

Automatic continuous focusing (AF-C): It is mostly used for shooting moving objects, and continuous focusing is used for shooting.

Manual focusing (MF): Manually adjust the focusing mode, which is similar to the contraction and extension of the lens of SLR, so that the focusing is completely controlled by yourself.

In fact, this focusing method is of little use on mobile phones. Because I usually focus with my fingers. Although it is not commonly used, it is still very powerful under special circumstances. For example, automatic continuous focusing (AF-C) can be used to capture objects moving at high speed, so that the focus can be tracked without manual clicking.

5: White Balance (AWB)

AWB stands for white balance. What is white in the sun? What about the white under the fluorescent lamp? Is to input the color temperature at that time into the camera. Simply put, it is to tell the camera what is white at this time.

I often see some comments that the white balance of the photos taken by XX mobile phone is accurate, indicating that the color is true and close to what I saw. I think the white balance of mate9 in bright mode is definitely not accurate. . . . You know why. In fact, it is not very easy to use on mobile phones.

Let me tell you about mate9 here. The place where photos are taken now is not good, and it will be optimized later. Overexposure in automatic mode. For example, taking a night scene is very dark, but the photos taken are brighter. I hate this setting. Night is night. A really good camera phone doesn't mean that your camera is good, because the night scene you take is very bright. This setting first appeared on the Samsung S series, and it is really bright to take pictures at night. Mobile phone Xiaobai said, Wow, it's good to take pictures with Samsung mobile phone. How about taking pictures at night during the day? ! ! ! ! So how to avoid excessive explosion? It's simple. Just take out the professional camera when taking pictures, and then take pictures. Yes, just draw it, and you don't need to modify any parameters, it's as simple as that.

Wall cracks suggest that everyone use professional mode, even if it is to adjust an EV. In fact, the most I shoot is to adjust this exposure compensation, which is a fixed value after adjustment. Compared with the sliding exposure compensation of the camera interface, this is easier to use and will not be readjusted because of changing the focus.
