Photographic classification of stunts

Special photography is a professional photography technique, which is said to have been discovered by a filmmaker through accidental mistakes.

Special photography methods can be divided into four categories.

1. Operation mode of the camera;

2. Install optical devices on the camera, such as the filter of the camera;

3. In post-production, special processing methods are used in imaging or optical processing;

4.Go-Motion, Hugh Noguuoeres, motion control and other techniques used in shooting miniatures.

When making Block Burster, if there are many special effects scenes, in addition to the general director of photography, a special director of image photography should be selected to take charge of special photography. Because special photography itself needs photographers, photography technology is completely different from general plot photography. The famous Dennis Mullen of ILM is also the director of special effects photography.

Roland morici, who is famous for Independence Day and other films, also hired a photography supervisor named anna foerster. Although anna foerster is a woman, she faithfully performs the special duties of photography supervision that many men are not competent for. Her strength has been recognized by people in the industry, so she is famous. In order to adjust the scale, you can use high-speed photography to shoot slow-motion scenes or miniatures by operating the camera.

This technique is common in movies directed by John Woo, such as the scene of Chow Yun Fat holding a gun in both hands and a slow-motion gun battle in "Hot Men". The film is shot at a speed of more than 24 frames per second by operating the camera, and then projected by the projector at a normal speed of 24 frames per second. In this way, the movement of the object becomes slower relative to the number of frames.

Generally, you shoot at 50/28 frames per second, and you get slow motion. Miniature explosion scenes and dramatic action scenes mainly use high-speed photography. This is also the way to get special effects by operating the camera. Contrary to high-speed photography, this method can achieve fast motion effect.

After shooting at less than 24 frames per second, you will get the effect that when you show it at normal speed, the speed of the image is faster than the speed of shooting the frame. To show people the process of flowering or sunrise in a short time, it is necessary to use low-speed photography. diminutive

At present, motion control cameras are widely used in miniature photography, and sometimes ordinary cameras are also used. In the past, Hugh Noguerrez camera was used.

Hugh Noguuoeres camera uses the principle of periscope to connect a long tube with a small lens and a mirror with a TV camera and a general camera to shoot objects. The mirror attached to Hugh Noguuoeres lens reflects the image to the mirror attached to the camera lens, and the camera takes the image reflected on the mirror. In this way, you can get the original action control shooting effect. This shooting method is generally used when the object quickly enters a narrow space that cannot be directly photographed by the camera.

Hugh Noguerrez's photographic masterpiece is the scene in which the X wing rushes to the surface of the imperial army Das in the first episode of Star Wars. The staff action photography mentioned here is not the staff action photography technique like clay sculpture animation. Clay animation, a staff action, takes pictures one by one while moving the subject bit by bit.

What I want to talk about here is the 360 still scene photography technique appearing in Hume's advertisement. Of course, staff action animation photography such as A Christmas Nightmare is also called staff action photography. In Hume's advertisement, the staff sports photography takes the subject as the center, and arranges a single-lens reflex camera-still life camera, which is commonly used when people take pictures, in a circle or a row at a certain interval, and shoots at the same time. In this way, the still camera can take still pictures from multiple angles. When editing these pictures, stick them together to form a connected image.

This is 1996 newly developed by a British special effects photography director. This requires very precise photography. At present, only two or three people in the world can use this technology. Therefore, 35% of the production cost of Hume CF was paid to the British who were in charge of staff action photography. In Block Burster, you can see this technology in recent movies such as Lost in Space. Motion control photography is a technology developed to overcome the shortcomings of GO sports photography and Hugh Noguuoeres photography. It was developed for Star Wars by John Deist, director of photography at ILM. Motion control camera uses high-precision camera control device to accurately grasp the viewpoint motion of Yuntai and shoot one picture after another. The audio computer completely controls the movement of the camera, just like using path to guide the path of the camera when making animation with 3D program, which can get smooth and natural photography effect.
