step

First, choose a SLR camera to shoot video and use a tripod to stabilize the picture. When the picture is unstable, the short film shot at any time will become very blurred, and even the real subject can't be seen clearly, which leads to the content in the shot video can't be recorded well, and even shooting is meaningless.

Secondly, for the focus of shooting video, the shooting mode can be adjusted to creative shooting mode, that is, there is a small TV button on the SLR camera, which belongs to real-time shooting mode. Start this button, but it is difficult to shoot short films in basic shooting mode.

When the mode dial is set to the creative shooting mode, the mirror of the SLR camera will sound, and then the image will be displayed on the LCD screen, and you can shoot the picture. When shooting a short film, you must focus on the pictures you shoot. Auto focus mode is generally adopted. Press the button with a special symbol on the right side of the SLR camera. The special symbol is *. Find this button on the SLR camera, and then press it to automatically adjust the focus, and the picture will be slow. Don't aim the lens at the sun when taking pictures with autofocus. The heat of the sun will damage some important parts inside the camera.

Click the menu button at the far left of the SLR camera. When the shooting mode is set to short film shooting mode, three autofocus modes will be displayed on the menu, namely, real-time mode, fast mode and face priority mode. For the real-time mode, you can move several direction keys on the left side of the camera, with up, down, left and right keys respectively. When the selected short film screen is to move to the right, at this time, the short film content on the right side of the screen is focused. If you want to adjust the autofocus point to the middle position of the picture, then you can press the delete button in the camera at this time, and it will display the recovery button, which will automatically adjust to the middle position of the picture. Press the meter key, and the meter key is *, which means the meter key. When focusing, you will hear the camera make a sound, and click it, which means you can shoot normally.

For the focus mode with face priority, it also belongs to the range of autofocus mode. Similarly, turning on the shoot button first belongs to the creative mode. Then, when you press it, you will find that the picture comes into your sight, and the face priority mode is usually to shoot faces in a wide range. When some positions of the face are detected, it can be found that a box will appear when focusing. At this time, you can press the left and right keys to adjust. Press the meter key after adjustment, and then focus automatically, and the focused picture will be clearer. When you press a dot button on the left side of real-time shooting mode, you will start recording video, which means shooting video. Click again at the same time, indicating that the video clip is over.

Auto-focusing takes a long time, and it is relatively difficult to focus on the subject on cloudy days or in poor light, so there is another mode: manual focusing to shoot short films. Switch the focus mode of the lens to MF. MF mode belongs to manual focusing and AF mode belongs to automatic focusing. This button is around the lens and is easy to find. Then, select the left and right buttons to move to the appropriate position. You can clearly find the subject in the picture by enlarging the picture button. The zoom-in key is a plus key on the right side of the SLR camera. Every time you zoom in, it is equivalent to magnifying the picture by 5 times, and then pressing the shutter button halfway. At this time, the picture can also be clearly displayed. You can focus by adjusting the position of the lens. When the lens is constantly pushed and pulled, the photo will be clearly displayed, and then it will not move after focusing. Generally, a tripod is used to stabilize the picture, and at the same time, the main content of the short film can be made clearer.

In addition to manual focusing and autofocus shooting short films, it is also necessary to master the time of shooting short films. Generally, video clips shot by SLR cameras can withstand a long time, even between half an hour and 1 hour. SLR cameras can also shoot short films, and can withstand short films of about 20 seconds to 1 minute. It is recommended not to shoot for too long, because shooting for a long time will cause beauty.

When shooting a short film, you can choose a soft light filter to shoot. Using the soft focus filter can make the characters softer under the sunlight, make the picture more dreamy and make the content more meaningful. It is one of my hobbies to practice photography and minor in photography. For professional photographers, it is best to choose a polarizing filter, which can make the colors of photos more vivid, and the clarity of natural photos is the first basic condition.

When the subject is very small, even at the edge of the photo, it is generally difficult to focus. When shooting a short film at high temperature, the camera will automatically remind you of the high temperature. When you make a short film, you will find that the quality of the film is relatively low. Therefore, if you want to choose auto focus mode or manual focus mode to shoot, you need to be flexible. Appropriate cooperation with the hood can better adjust the visual range of the picture.
