Director’s Legend

"Look at this, I figured it out with Hatton. We placed the imax camera on the top of the jet remote control aircraft and controlled the aircraft from the Oriental Pearl Tower to the Dongpu New Area. Looking at this group of scenery, the sun is rising and the sun is bathing. , The whole city is like a set of scrolls, beautiful."

Four days later, the shots of the magic city, including the rooftops, airports, trains, and hotels, were taken. At the same time, the photography team also completed the aerial shots of the city. Huang Yuetai is now showing the results and playing a set of copies.

"Look at this group again. It is an aerial shot at night. Tens of thousands of lights are collected in a group of shots. The two most beautiful moments of the magic city are not missed. Putting them in the movie can definitely greatly increase the texture of the picture. Oh, and this group of high-speed train situation shots, which is very powerful. Look at this, it is an aerial shot of the Huangpu River. Does it look like a jade belt interspersed in the city?"

"Very good results, so much material, enough for me to edit into the film. By the way, have you watched it for the city government?"

"Wang Wei sent it, and the city government wanted to keep a set of copies. For safety's sake, we didn't agree, meaning that we would send it back after the movie was released."

"It's right to be on the safe side." Shao Shuaijun nodded, "By the way, Huang, I heard that you and Bob have been working on high-speed lenses lately at night. How is the research going? Call the camera team over and let's do it. Experiments?"

High-speed lens shooting requires high-speed photography technology, and the so-called high-speed photography is simple and simple to say, not simple but not simple.

The time resolution of the human eye is only 1/24s. In other words, we can see 24 sets of pictures in one second. Simply put, we see 24 images in one second, which make up the actions we see. But the movement is discontinuous. It consists of an array of static actions, such as throwing a flying knife. You may only see the flying knife flashing past. In fact, the flying knife has more trajectories left behind, which is trapped by human eyes. Ability, invisible.

Therefore, the frequency of filming and screening is 24 frames/s, and 24 frames flash in one second. This allows us to get the feeling that the movie is continuous and the characters are always moving without pause. But many high-speed moving objects. Or transient phenomena, we cannot see clearly.

And high-speed photography is to clearly show this kind of change that is invisible to the human eye. It is a very fast shooting speed and short exposure time. The human eye can only "see" 24 pictures per second. High-speed cameras can see hundreds, thousands, tens of thousands, or even hundreds of thousands, millions of images in one second. Then it is exposed on the film. After being washed and decompressed, it will be played in 24 frames per second. People can clearly see this change.

A typical application of high-speed photography is bullet time. The bullet passed by in a flash, but it can be greatly extended in the movie to give a strong visual conflict. Shao Shuaijun has always been eager for this kind of application. Now that he has the opportunity, he naturally has to study hard.

Especially in "Inception", the time of dreams is different from the time of reality. Five minutes in reality equals one hour in dreams. In order to achieve this time comparison, high-speed photography is a very good way to clearly show the time.

"Hdcam-sr high-speed camera, photo-sonics-4er lens, the perfect combination. Let's first present a high-speed camera with an apple into the water?" Bob Adams combined the camera while being civilized. This camera is a high-speed camera for professional use in movies.

High-speed cameras were originally used in scientific research and military applications to record tiny or difficult-to-capture experimental phenomena. There are many categories. Principle: Spectroscopic type and optoelectronic type. The results are divided into scanning cameras and framing cameras. The shooting speed is divided into low and medium speed, high speed and ultra high speed. The one currently in use is an optical-mechanical ultra-high-speed framing camera.

Simple and effective.

"Very good, very good, I have turned on the camera and the lens is very clear. Very good, Hatton, drop the apple!"

Squeak!

The sound of the camera running is clear and audible, clicks, apples enter the water, water splashes everywhere.

Then a group of people took the film and went to process the printing. After about half an hour, the copy came out. It was shown on a small device and the picture was clear.

An apple slowly fell into the water, as if a circular pit was smashed on the water, and it was as if a flower suddenly bloomed on the water. The trajectory of the water droplets is clear and clear.

"Wow! Very beautiful!" Shao Shuaijun admired.

"I can already imagine that when Leo falls into the water, just like this big apple, let the water in the bathtub blossom and bear fruit, haha." The deputy director Inst laughed.

Bob has a calm face: "It's not enough. The exposure range of high-speed photography needs to be corrected. This time the light obviously doesn't meet the color tone I want, nor does it meet the dream-level picture sense of the director."

Inception is very complicated, and even some viewers may not even know which level of dreamland they are in. Even the actors in the crew are often confused as to which drama they are acting in. Therefore, Shao Shuaijun formulated strict photography standards, and the main colors of different dreams must be distinguished.

For example, in the opening scene of the script design, in the palace of the golden dragon, the required color is nostalgic, so the light and the dialogue of the characters must conform to this main color. Then fall back to the first level of dreams, which is in the mistress's nest secretly built by the golden dragon, so the color is hot, and then back to reality, it is a cool color, so that people know at a glance which level of dreams they are seeing.

"Bob, we are going to shoot in the palace tomorrow. Let's put these experiments aside. The palace section requires us to work hard to shoot and set the tone for future shooting. Buildings collapsed, stone statues destroyed, etc. Wait, you need the cooperation of your photography team and special effects team, as well as the scene of flooding, we better pass it at once."

In the palace there is a very magical shot to show, that is, Leo is pushed into the bathtub, and the real senses affect the dream. In his dream, huge water flooded the entire palace.

In order to achieve this effect, Shao Shuaijun and the props team have negotiated to prepare about 20 tons of water, put them in boxes, arrange them in the windows of the palace, and then uniformly infuse them to simulate the shots of flooding. It is conceivable that a palace built with so much water will inevitably suffer a devastating blow.

In case of a mistake in the lens, it takes time and effort to re-shoot.

It can be said that this lens can only succeed but not fail. (To be continued, please search Piaotian Literature, the novel is better and updated faster!
