Chapter 129: Simulating the Light and Shadow Effects of Femtosecond Imaging

In the mainland, there are very few directors who can play tricks on technology to make commercial films, because the things here are very complicated, so complicated that even if you graduate from a junior college, you have to soak in these things every day to understand them. When a director needs to take care of so many things, technical things will become a burden, so most domestic directors care about whether the storytelling technique is new, and few people have innovated in shooting technology.

For Wang Jiawei, he likes these burdens, not only likes them, but also enjoys them. This is also the main reason why he went abroad to find John Tolle to take charge of the computer, because now Wang Jiawei has to use the technology that he can't even control himself.

"What's going on?"

Shao Yingying was in the dilapidated train station and the crew hid in the abandoned waiting hall around the stove to keep warm, it was already eleven o'clock at night, and the field workers had already prepared a qiē, but Wang Jiawei just didn't say that he was ready to shoot, and he was alone in the snow and John Thor, you and I talked endlessly, and talked while gesturing.

Zhang Ziyi was about to fall asleep by the stove, and Zhang Zhen also chatted with these people without saying anything, and the whole scene was quiet and sleepy.

Can't film this scene yet? How can you shoot a shot overnight? Wang Jiawei is too inkblob, right?

Thinking of this, Shao Yingying stood up and glanced out the window, and at this time, he happened to see Wang Jiawei shouting with a walkie-talkie: "Field worker, take out all the equipment." ”

All devices??

This sentence shocked Shao Yingying a little, and the character dialogue in the next scene was at most three machines. One uses a wide-angle panorama to shoot the positions of Shao Yingying and Zhang Zhen, and the remaining two give close-ups to these two for post-editing. However, there are a total of ten machines in their group, and these ten machines were brought back from abroad at a great cost, so are they going to be used now?

The field worker moved his body a few times, so that there was a trace of heat in his body before he went up to move the machine, the boss said, these things are as expensive as life, if anyone breaks it. With their salaries, I am afraid that they will have to work for Huayi for free for decades to redeem their free body, so can they not care?

After the machines were delivered to the scene one by one, ten tripods were erected at the scene. John Tolle personally visited the location of the machine with one hand and one foot, and at this time, he was the general dispatcher of the scene, and only he could say what he said about each machine. Even Wang Jiawei could only put forward requests from the sidelines, unable to participate in specific matters.

"Director Wang. What are we doing here? How did you dig out all the money from the house? Shao Yingying followed the field worker out of the waiting hall, and while the field worker and John Thor were busy, Shao Yingying approached Wang Jiawei and asked.

Wang Jiawei said proudly: "Now we have to shoot a shot that other domestic directors are dumbfounded after watching it." ”

Shao Yingying is a professional in doing this, not to mention that the things in the crew can be picked up on one shoulder, it is almost the same, but when he heard Wang Jiawei say this, he asked: "Even if others use our machine, they can't shoot it?" ”

"I'm going to shoot the speed of light!"

Hearing this, Shao Yingying had respect when he looked at Wang Jiawei for the first time.

An interesting picture appeared in his mind, and that was when the light of the street lamps on both sides was shining. Little by little, the light cluster slowly lights up the entire set at a speed visible to the naked eye...... It's just that. He didn't quite know under what circumstances the shot would be taken and where it would be edited.

It's like he's not Wong Kar-wai if he doesn't play tricks, how can there be such a thing as a shooting technique that is not agreed with the actor in advance, so how will the actor cooperate in a while? Who is NG counted when there is one?

"Don't understand?"

Wang Jiawei explained: "Do you know what 'femtosecond imaging' is? ”

Shao Yingying felt that Wang Jiawei was crazy, like a martial idiot who had fallen into his own world, and he couldn't extricate himself.

'Femtosecond imaging' is still only a theory for today's photographic methods, which are said to be able to shoot light in slow motion, and even show the trajectory of the laser in front of the viewer's eyes in slow motion.

However, the equipment in the hands of the crew is absolutely unable to complete this miracle, which was developed in 2011 by the MIT Media Studio and BAWENDI of the Department of Chemistry, and the high-speed shooting was developed with a lot of money. With such powerful photography technology, it is possible to obtain a film with a frame rate of one trillion frames per second. This equates to an interval of only one picosecond between frames, and light can only travel 0.6 millimeters in a vacuum in such a short period of time, so the technology allows scientists to observe the details of the movement of light pulses through objects.

To explain the 'femtosecond imaging' technology in the best way to understand it means that if the machine in Shao Yingying's hand records a 1-second event at the highest frame rate and plays back at 30 frames per second, then the machine owned by Shao Yingying can play back this second for more than 9 hours, but once it is replaced with femtosecond imaging technology, then, the same one second, with the same 30 frames per second, femtosecond imaging technology can be played back for thousands of years! Regardless of the effect, light storage is a huge problem.

"Isn't femtosecond imaging just a theory?" When Shao Yingying was thinking about the problem, he said casually, for the current era, femtosecond imaging is indeed just a theory, after all, it is only 2006.

Wang Jiawei said very mysteriously: "I didn't say I wanted to do it, I just wanted to simulate 'femtosecond imaging'." ”

"What do you mean?" Shao Yingying looked at Wong Kar-wai and asked.

Wang Jiawei didn't explain, pulled an extra and whispered a few words to Zhang Zhen, and then, six cameras were aimed at the street lamp, and among the remaining four cameras, two were aimed at the distance, and two were aimed at the position where Shao Yingying was about to get out of the car.

The crew left the scene with the benefit of Wang Jiawei, which began to become a mystery in Shao Yingying's eyes, and the crew entered a state of readiness at the moment after John Thor and the gaffer had done their work with each other.

"Prepare !!!"

Shao Yingying heard this shout and hurriedly boarded the train, and more than a dozen people around him crowded into the aisle of the same carriage. Those who are in charge of playing his apprentices.

"Let's go!"

Woo!

There was a whistle from the train, followed by a stream of white steam from around the train. Shao Yingying slowly walked off the train with his apprentices in the stars and the moon, this qiē is normal, at least so far.

Syllable.

Just when Shao Yingying and the others had just stepped off the train in cotton robes, the lights on the abandoned station were all extinguished.

Shao Yingying almost subconsciously looked up and looked around, and the extras around him surrounded him in the middle for a moment, and began to be on guard with a protective posture.

At that moment, Shao Yingying suddenly understood. Wang Jiawei wants his most realistic reaction after the lights go out, but what does this have to do with the simulation of femtosecond imaging technology?

The gaffer's lights were always on, but none of them were aligned with the angle they were shooting. Instead, the guò light shield is used to create a very soft halo, which spills out the halo from afar, which is very soft and smooth, and looks very much like moonlight.

Distance. One was wearing a suit and waxing his hair. The man with the hair on the top of his brain can reflect the light appeared in the dark, he used one hand to pinch the cigarette butt with his thumb and index finger, and made the cigarette butt constantly contact his lips with continuous movements, causing the cigarette butt to flicker and darken, and when the cigarette butt was popped out by his hand, this person appeared under the light of the gaffer.

"Ma San."

Zhang Zhen is very calm, calm like an ice sculpture in winter, except for looking at Shao Yingying directly, there is no movement. Not even an expression.

Shao Yingying glanced at Zhang Zhen at this time, and put his hands in the leather hand warmth. Wearing a bullshit hat, he opened his mouth and replied, "I don't know you." ”

The two of them have no waves in their standing posture and affection, but this is obviously different from meeting strangers, and the two in the camera have a strong hostility, which is not shown from the expression, but under the director's arrangement.

In the monitor, the flow of people on the train is constantly shuttling in front of the two people, although the two of them stand still, but the two of them are the constant points of opposition to each other in the picture, and the flow of people has become a flow line, and the contrast between the points and the lines, these two people are corresponding and exist, and there will naturally be opposing results.

"You don't have to know me, you just know who you owe." Zhang Zhen's treasure island emphasis can still be heard, even if he can stand still.

Shao Yingying suddenly cracked the corners of his mouth, and adjusted a small arc smile at the slowest speed, he didn't show that he was full of evil intentions, just like seeing an ignorant child sneering lightly from an adult's perspective after peeing and stirring up mud: "Whoever you owe should be repaid, the things of the Gong family can only be taken by the Gong family, you are not worthy." ”

"I don't want anything from the palace family, it's fatal."

After Zhang Zhen finished speaking, he suddenly lowered his body, and rushed out with a step and swing arm almost at the same time, and the cheetah-like speed was presented for a moment.

Syllable!

The lights are on.

"Click!"

Wang Jiawei suddenly shouted: "Shao Yingying, why didn't you run!" ”

Shao Yingying still remembered that Yuan He told him that he had to run out, and he was shaken by the lights and went out directly.

Wang Jiawei didn't wait for Shao Yingying's response, and asked John in English: "How was the shot at the moment when the light appeared?" ”

John responded with an OK gesture.

Shao Yingying opened his mouth and asked: "Director Wang, I haven't filmed like this, you can't tell me nothing, let me react by myself, so who can react?" ”

Wang Jiawei asked, "What did action director Yuan Heping tell you just now?" ”

"Let me ...... I know I have to run, but you don't tell me when to turn off the lights, when to turn on the lights, and suddenly let the lights come on, and you don't let people know the up and down of the plot, I ...... I've never seen a director like this. Shao Yingying didn't know what to say.

Wang Jiawei took Shao Yingying's arm and said, "Come and see." ”

"John, connect the three machines 5, 6, and 7 to my monitor."

Wang Jiawei sat in front of the monitor and explained to Shao Yingying: "What I want is the shot of you suddenly stopping during the run, when you look up at the light that is on again, and the light source on the light shines down little by little......

The No. 5 machine Qì had been connected to the first monitor screen by John, and on the screen was a dark street lamp in the moonlight, and after Shao Yingying had waited for a minute, the street light suddenly turned on. Shao Yingying watched the filament in the bulb of the street lamp turn red, and watched the light bloom little by little under the shooting of the high-speed camera, the rhythm of the light blooming was very slow, like a flower blooming in slow motion, and the surrounding shadows were driven away little by little by the slow rhythm of the light; At this moment, the No. 6 camera also lit up, it was Zhang Zhen under the run, Zhang Zhen was ready to start at a very slow pace, and the light slowly fell on him in this scene, so that an actor who originally did not carry any highlight effect gradually filled with a sense of aura when the light fell.

Although they didn't capture the movement of the beam, they did capture the movement of light from being there to not being there.

This shot can be completely interpreted as Zhang Zhen becoming more and more courageous under the light, and Ma San, who ran out in the dark, suddenly stopped after touching the light, and took advantage of the astonishment that raised his head and was illuminated by the sudden light alluding to his identity as a traitor who could not see the light.

If the lens is cut out, it is very beautiful, and when the light source blooms, the particles that are shrouded by the light source; The highlight effect above the actor's head when the light source spreads throughout the train station; When the light source appeared above Ma San's head, it was completely opposite to the demeanor and expression of the scene, and the stunned expression on Ma San's face was all connected, which was the so-called lens language.

But that's too hard to guess, right?

Shao Yingying could estimate that Wang Jiawei might make up a shot of Zhang Zhen pulling down the train station switch, and the reason why he didn't tell him was to shoot his true expression. But who would have thought that the light would come on? Who would have thought that Wang Jiawei would not only want his expression when the lights were out, but also the stunned feeling that he suddenly stopped in a running state when the lights were on? Who can change this play? It's hard to find this time difference alone, Shao Yingying's eyes are not high-speed cameras, and he doesn't know when the lights will fall.

"Director Wang, can you sue me in advance next time? It's a big deal I'll give you a stunned expression, it's so neat, I really can't keep up. Shao Yingying turned his head and gave advice to Wang Jiawei.

"That wouldn't be real."

"I can't be real if I want to be real now." Wang Jiawei sighed, Shao Yingying's appearance did cause great difficulty to filming.

It's just that if you say this back, you really can't blame Shao Yingying.

"The others evacuated."

After Wang Jiawei said this, he said to Shao Yingying: "Let's take a single shot of you and the performers rushing over at the same time, remember, they can slow down when the lights are on, you have to give me a performance stunned, and then look up at the lights overhead, and look forward with your head down." After this scene is filmed, you are filming your action scenes. ”

Shao Yingying slowly walked from behind the monitor to the position he had just been, thinking about how to play this scene as he walked, while the others reset the position in the screen of the monitor. (To be continued......)
