Camera stunt problem

Different special effects techniques can be used according to the types and styles of movies, which are roughly classified as follows.

1 special makeup

2 Electronic animation (animation)

3 image composition

4 Model (Miniature)

Second, thematic photography

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.

1 high-speed photography

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.

2 Low-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.

3 miniature photography

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.
