Knowledge must be seen in the introduction of mobile phone photography

Introduction to mobile photography requires knowledge. In recent years, more and more people like photography. Many people like to record the details of their lives with their mobile phones, but you will find that their mobile phones are not as easy to use as others. Let's learn some basic knowledge of mobile phone photography.

Basic knowledge of mobile phone photography 1: main performance parameters of mobile phone pixels

● Pixel: The larger the pixel, the larger the shot video. However, too high pixels will also bring negative effects, such as too much storage space occupied by files and slow processing speed of mobile phones. We don't have to blindly pursue high-pixel mobile phones, but should choose mobile phones with suitable pixels according to actual playback needs.

The National Youth Science Video Festival requires that the resolution of participating films be 720×576 (pixels) or 1280×720 (pixels). At present, most smart phones can shoot 1920× 1080 (pixels) or full HD (1080P) video.

● Photosensitive element: also known as photoelectric sensor, it is the core element of mobile phone imaging system and the key factor to determine the imaging quality of mobile phone. Generally speaking, the larger the sensor size, the better the photosensitivity and the better the imaging effect. Therefore, if conditions permit, try to choose a model with a larger photosensitive element size for shooting.

● Algorithm: When shooting, the mobile phone converts the collected optical signal into an electrical signal, and then restores the video through a preset algorithm. Because of the different algorithms of different brands of mobile phones, different mobile phones have different shooting effects at the same time, place and shooting parameters.

● Aperture: Pictures taken in dark environment are easy to blur, which is related to the aperture of the mobile phone lens. The larger the aperture, the greater the luminous flux per unit time. Under low illumination, a large aperture mobile phone can obtain a higher shutter speed, which is very important for maintaining accurate focusing and shooting stability. Smartphone lenses basically use a fixed aperture, so choosing a mobile phone camera with a large aperture often has an advantage in imaging quality.

1, constitute

Symmetry and golden section are the most commonly used methods in film and photography, and they are also foolproof composition methods.

Symmetry: Scenes with the same shape are arranged from left to right or up and down in turn, which can form a symmetrical picture effect. Golden section: Using this composition can make the works reveal elegant and mysterious artistic temperament. You can use the "well" grid in your mobile phone to achieve gold composition shooting.

2, clever use of light (smooth light, backlight, side light, top light, prime time)

Light is the soul of photography. If you make good use of sunlight, you will take lively photos.

When shooting, we must pay attention to the relationship between the subject, shooting position and angle, and lighting conditions. Be good at using light, and be aware of the light before shooting.

Backlight: the light that shines from the back of the subject, and the shadow part is the subject of expression. The advantage of backlight is that the light is soft and the object will not produce too thick shadow. You can take photos with artistic charm by backlighting, such as taking a silhouette of the subject or taking a "silhouette light" effect.

Backlight is suitable for representing scenes with multiple levels before and after, thus producing strong spatial distance and good perspective effect.

When shooting, it is best to choose the middle tone or dark tone of the scene as the focus, so as to grasp the detail level of the scene. If you want to take a silhouette, you should focus on the brighter part. Suitable shooting time: noon is the worst shooting time, and the light is too strong to take pictures at this time. The best shooting time is early morning and evening, when the light is soft, which makes your photos have fantastic colors.

Divergent light: light from the front of the subject, and the illuminated surface is the subject. Most people like to shoot with smooth light. If the purpose of shooting is to make the background vivid and clear, the photo attracts people's attention and looks bright as a whole. Then, shooting along the light is a good choice. However, shooting along the light is easy to lack the distinction between light and shade, which often makes the scenery lack of three-dimensional sense.

Side light: the light shines on the object from the side, which not only makes the object have a certain contrast between light and shade, but also enhances the three-dimensional sense and spatial layering. As far as the color reproduction of the picture is concerned, sidelight is also an ideal shooting method.

But if you shoot with a mobile phone, it is not difficult to use metering skills. Need to focus repeatedly, try to click on a bright place to shoot, and try to compare it many times to succeed.

3. Know your mobile phone.

Mobile phones usually have the following functions:

Scenes: including ordinary, intelligent, macro, portrait, scenery, sports, night scene, snow scene, etc. , close to professional SLR. If you have enough time, you can choose the corresponding scene before shooting. Most people shoot spontaneously, so you can set the scene to "smart" mode.

Face recognition: basically all smartphones have this function. All you have to do is wait for the white box to appear and press the shutter in your face. Beauty: In view of the needs of the majority of girls who love beauty, beauty functions came into being, and various functions such as peeling, whitening and acne removal can be realized while taking pictures. However, it should be noted that this option should be turned off when shooting landscapes, otherwise the shooting quality will be affected.

Panorama: Panorama function is a very interesting function, which can only be completed by post-production with digital camera and tripod. Now, all you have to do is lay the phone flat and turn it around. Slow shutter: This function is no longer a patent of SLR, and now smartphones already have this function.

If you want to shoot endless crowds and traffic at night, you can use this function to create interesting light graffiti. You can also try to keep the mobile phone and the subject in synchronous motion or relatively static relationship to capture the pleasure brought by speed.

4. Focus

The focus determines the visual focus of the photo. Most mobile phones can achieve autofocus, but this can only take care of most shooting needs. You can also specify the focus position manually, so that the focal length can be more accurately aligned with the subject. By setting the foreground. Mid shot and perspective can make your photos more layered.

Usually, the subject should be placed in the middle position, and the focus should be placed in the middle position, so that the prospect and prospect are blurred. If the photo is not vivid, you can shorten the shooting distance, lower the viewfinder position and fully capture the details.

5. Creative photography

Clever photos can be taken by means of dislocation, mirror, glass and multiple exposures.

6. Filter

There are many filter modes to choose from in mobile phones, and some mobile phone applications (apps) also provide many choices for filter lovers.

Everything under the black-and-white filter is covered with a faint sadness, and there is a feeling of vicissitudes of life.

Nostalgia filter reflects a sense of accumulation of time, allowing you to relive the past years.

7. Objects, scenes and stories.

The object is the center and subject you want to shoot. Only by defining the subject can we better express the theme of the photo. Do you want to shoot the line outline of the subject, or its color or speed? Think about what to shoot, and then think about how to shoot.

Background is the environment in which the subject lives. The background should serve the subject, form a certain relationship with the subject, or exist to create an atmosphere or enhance the story. When shooting, remove the background elements that have nothing to do with the subject and the story. The decisive moment is to be good at capturing the picture and keeping the best moment of things. This is especially important when catching children and pets.

Stories are the soul of photos. Taking photos of stories is easier to attract people's attention. Now, people begin to pay more attention to the story explained by photos than to the photos themselves.

Must-see knowledge for the introduction of mobile phone photography III. First, master the light and mode adjustment.

Anyone who has a certain knowledge of photography knows that light is an important factor affecting the imaging quality. Mobile phone cameras, like cameras, have high requirements for light. Therefore, if you want to shoot a good work, you must choose good lighting conditions and try to avoid shooting in the back light. Some mobile phones can meet the light source through external conditions, and can also be adjusted through the built-in auxiliary functions of the mobile phone:

1, adjust the brightness. Many mobile phones can adjust the brightness of the camera and can be used when the light is insufficient.

2. Night mode. It can be used not only at night, but also in night mode in case of insufficient light during the day to obtain better brightness. It's just that it takes a long time to take a picture after turning on this mode. If your hands shake slightly, the photos you take will have double images.

Step 3 flash. The flash on the mobile phone is actually a bright LED light, which can effectively fill the light when turned on, but the effective distance is relatively short, which is suitable for close-up shooting.

Second, coordinate hand holding and shooting posture.

Users who like to take photos with their mobile phones may be impressed. The camera phone is only that big and weighs less than half of the ordinary traditional camera. If you are not steady when shooting, even the best light will be ugly. In particular, CMOS cameras are more sensitive, and slight vibration will directly affect the imaging effect. When shooting, the right hand holds the camera at the subject, and then the left hand holds the right hand to keep it stable.

Because the response speed of the mobile phone is not as fast as that of the camera, it is not taken immediately after the camera shutter is pressed, but only when the shutter sound rings, so it is best to set the shutter sound when taking pictures, and the mobile phone must be held firmly when taking pictures. Especially when you press the camera function key, if you move at this time, the picture you take may be blurred, so you must keep a steady posture until you take a picture.

Third, pay attention to the parallelism between the mobile phone and the scenery.

If your photography skills are not good enough, and you haven't reached the level of freely using the perspective, you must pay attention to the parallelism between the mobile phone and the scene when shooting, that is, the plane where the mobile phone is located should be parallel to the plane where the scene is located, especially when shooting beautiful MM. If you don't master it well, the portrait will be easily deformed.

Fourth, your brainwave.

In fact, many good photos are brain waves from the brain. Nowadays, the camera phone is more and more powerful, and various styles of photo frames have various shooting effects. You can give full play to your imagination and skillfully combine various functions. Perhaps your photos are not only different, but also rare creative works.

Here, I only talked about some basic skills of taking pictures. What's more important is the significance of taking pictures, showing the truest side with the most ordinary pictures. Show the most beautiful world with the simplest colors, and I believe your life will be more exciting.
