In fact, Chen Feng's storyboard script for Xu Tianliang and others in the camera crew has fully considered this, and the lens design on the script is very careful, so as to make the audience's eyes naturally follow the movements of the characters. This requires avoiding placing a lot of action at the edge of the frame, as well as at too high a position, and not moving too fast through the frame to maintain the viewer's attention.

In addition, considering the scope of the photography and the amount of detail in the frame, it is important to carefully design the focus area and the composition of the action, so that the viewer can know what to see in the image without thinking, and only then will they be engaged and felt. So you can't use a shallow depth of field, and you can't use a depth of panorama that is full of focal points. Unfortunately, in addition to the problem that this electronic viewfinder is too dark, the marking of the rules that guide the composition also causes a lot of trouble for directors and cinematographers who are not used to this format.

Chen Feng didn't seem to be affected by anything, and quickly got used to it; And the old guy Xu Tianliang had a headache for this, and adjusted the brightness of the aperture of the lighting system to seven levels, and finally saw the problem clearly, he agreed: "Yes, the shallow depth of field will become terrible, well, we can only adjust the focal length and aperture one by one to see the effect...... "To find the most suitable depth of field blur level, which highlights the focus area and is not ugly."

"Try the panorama first, 80mm focal length, I think 80mm will be good." Chen Feng took a few glances at the separate director's viewfinder, combined with the electronic framing just now. Speak your own judgment. Xu Tianliang adjusted the focus on MSN-9802, observed it for a few seconds, and said, "It does look much better." Very close to a normal view. I'm not so sure, it's too dark. He got out of the way. Xue Mingshan, other photographers, and special effects directors all took a look, but they couldn't give any conclusions because they were too dark.

You can't raise the brightness by another level, because the camera lighting is mainly T32 when shooting, and the effect is different when it comes up. Fortunately, the decision-makers have a good eye, and they still have to be directed.

"Not bad." Chen Feng bent down to aim at the viewfinder, the t32 level of brightness allowed him to see more clearly, although he had not seen it on the IMAX screen, it was almost certain that 80mm was the ideal focal length. The depth of field can be shallower in close-ups, and he adds: "Try 110mm" aperture and reduce it by one stop. ”

The scene in front of me suddenly changes, and the few trees in the distance at the left edge of the frame are so unsightly that this focus is distracting. While composing, he asked a nonsense: "Director Xue, those trees on the left can be erased by computer, right?" ”

It doesn't work to just let the crew and set team run up and cut them down, and they don't want to destroy the environment at will, except for the law; And the location of this town has been selected for a long time. The nearby terrain is not suitable, so you can only count on this technique, and erasing a few trees is naturally a piece of cake. Xue Mingshan replied without thinking: "Yes." Chen Feng clapped his hands and left the camera and said, "Xu Tianliang." The focal length is 110mm......" He took the speaker from the assistant and shouted, "Ready, ready!" Everyone prepare!! ”

"Okay." Xu Tianliang answered the call and adjusted the camera. Liu Tianhua, who heard the director's shout, and several other leading actors came over; Ye Rong also smiled and got up and ran over to watch the excitement.

Just like every day on the set, the performances, script lines, sets, cinematography, etc. Today there is one more. Their beloved Director Chen solved another troublesome problem and soothed the bad IMAX projection effect in the cradle.

“action。” As the first assistant director Xue Mingshan shouted to start, the cameras set up around were suddenly turned on by Xue Mingshan, the camera faced the hillside in front of him and a wave of higher hills, and the film disc that only lasted 3 minutes began to rotate, and the camera team operated the entire photography system; At the same time, there is a digital film camera shooting at the actors. …,

Images shot on IMAX film cannot be watched immediately on set; With the digital camera, the replay can be watched almost as much as they want, and the film crew no longer has to worry about the goofs in the background and can't find it, because the video tapes used to be used for on-set playback are of poor quality and difficult to show the details in the picture, but the digital images can be seen in great detail on a large color HD monitor, even if they shouldn't be seen, they will be seen clearly. Chen Feng said when he scared Ye Rong: "Why is there an extra person behind you?" ”

No matter what the lighting quality of this camera, the main purpose is to allow the director to observe and check the performance and movement of the actors, and directly make changes and instructions, of course, it also means that a film is invalid.

"No, card" a plate of film was reimbursed, everyone stood in front of the 26-inch monitor, the power supply cable on the ground extended to the power supply car in the distance, only to see the screen on the hillside, Chen Feng, dressed in military uniforms, gray-haired, Yerong, Liu Tianhua, and several mass performances behind slowly walked a few steps forward, staring at the distant sky blankly. Xue Mingshan, who was holding the remote control in front of the screen, pressed the playback again, and frowned dissatisfied: "No, no!" The guy on the left is too badly acted. ”

Chen Feng frowned, walked to the camera and looked at the replay, indeed, the person on the left was too anxious at first when he walked, and then slowed down abruptly in order to keep up with everyone's rhythm; The demeanor performance was completely expressionless, and he was not even surprised...... What does the casting director do! Where did you find such an unprofessional extra?

The speed of the movement and the swaying of the limbs are only secondary, and the expression is the biggest problem. Thinking of this, Chen Feng stepped forward and said to the extra: "Brother, your expression just now is not enough. ”

"I see, I'll pay attention next time." When facing Chen Feng, the extras were still quite stressed, and said tremblingly.

Chen Feng nodded, brought him to the camera, and pressed the playback again, when the picture stopped in the middle of the three people, Chen Feng pointed and said, "Look, you are completely sluggish now, a little surprised, this is good." But next, what about the level change I asked for earlier? "I pressed the remote control, and the picture on the screen stopped in the close-up, and sure enough, there was no obvious change.

Chen Feng looked at the extras and said, "You know this is slow motion, don't be afraid that the camera won't be able to capture your micro-expressions, I need that moment, to know that the moment when the defeat of the government army is real, you are about to cry, and you can hold back!" Patting the extra's shoulder, Chen Feng continued: "Don't forget that you are now a soldier, the home you are guarding and the planet you are on has been occupied, understand?" ”

The extras nodded: "Understood, Director Chen." Chen Feng nodded, and then looked at Xue Mingshan. Xue Mingshan nodded, indicating that he understood, he picked up the microphone and shouted: "Clear the field, clear the field!" All the idle people are away from the performance area! Ready to get started. (Your support is my biggest motivation.) )
