Niu Decai said with obvious sullenness on his face.

"Now that you have read the introduction, why are you still asking me? If everyone can understand everything by reading the introduction, then why is the profession of a teacher still needed in this world?"

Seeing the silence among the students below, Niu Decai seemed to think that his majesty had suppressed these students, and he puffed out his chest and said.

"This student, if you don't want to listen, or don't trust the teacher, you can give the opportunity to the next student!"

After Niu De said this, he glanced at the students below.

Seeing the students stunned one by one, I thought they were subdued by my "powerful spirit", and I felt a little proud.

In fact, the students' minds were completely contrary to what he had guessed, especially the student who gave him the photo, he thought in shock.

"I'm afraid this teacher is a fool! Didn't you say that I wanted to discuss the photos with you? Why do you feel like someone stepped on your tail?"

The first time Bai Zhou saw this photo, he was sure that the portrait was lit just right with five lights!

He was certain that the two lights Niu Decai mentioned would never produce such an effect.

When the student put forward a different point of view, Bai Zhou thought that a good teacher-student discussion and an atmosphere of common progress would emerge.

Unexpectedly, this Niu Decai actually said such words. For a moment, Bai Zhou looked at Niu Decai and shook his head inwardly.

"How did such a person become a university teacher just because of a postdoctoral diploma?"

Niu Decai's clown-like performance wasn't over yet, so he pointed at the student and said.

"If you don't believe me, then you don't have to attend my course. Go down and think about it carefully, and don't delay the next classmate from asking questions!"

Bai Zhou, who was watching on the sidelines, was now a little unable to keep up with the thinking of teacher Niu Decai.

"Did he experience something that stimulated his brain?"

But Niu De had forgotten that he was now facing sophomore students.

The education in universities is completely different from that of middle school students. An equal teacher-student relationship is advocated in universities, so Niu Decai's self-righteous curse had an obvious counterproductive effect.

Immediately, a girl took a step forward and spoke sharply.

"Teacher Niu, you yourself said before that you want everyone to discuss issues with you. Now that the students have raised questions, what's the matter with your attitude?"

Niu Decai obviously did not expect this to happen. He was stunned for a moment, and then immediately raised his voice an octave.

"What's my attitude? Let's see what your attitude is first. Have you ever talked to a teacher like this? Which class are you in? I want to have a talk with your counselor!"

"Me?...Ha..." The girl was furious and had a speechless expression on her face. She didn't know how to communicate with Niu Decai.

Soon, the student who provided the photo spoke.

"In that case, we are in the laboratory. Can we ask Teacher Niu to restore the shooting situation of this photo to us?"

Niu Decai saw that the development of the situation was completely opposite to what he expected, and he was a little panicked.

Pointing at the students below, "Are you...are you provoking the teacher?"

One student responded disapprovingly.

"We didn't provoke the teacher, we just wanted to ask the teacher to teach us the skills of portrait shooting."

"Okay...Okay!" Niu Decai looked obviously frustrated.

"I'll show you the difference between professionals and amateurs!"

As he spoke, he took out a tripod from the corner of the laboratory and placed his 5D on it.

Then I found an LED light as a steady light, placed a flash in front of the right side of the camera, installed a flash trigger, and placed a chair in the middle.

Niu Decai's movements are skillful, and it can be seen that he is indeed studying this major.

After doing this, he sat down on the chair and looked at the student who had been providing the photo.

"You, you used my camera to take pictures!"

The student walked up to the triangle and asked.

"Teacher Niu, how do you adjust the camera parameters?"

Niu Decai laughed contemptuously.

"I've already adjusted the parameters. You don't have to move, otherwise you'll spoil it! Just shoot."

"But..." the student said, looking at the mode displayed on the camera.

"This is obviously full automatic mode?"

"That's enough, let's shoot!" Niu Decai obviously felt embarrassed about being exposed.

The student pressed the shutter hesitantly.

There was a "click" sound, the flash in front of the camera flashed, and a photo appeared on the camera's LCD screen.

Bai Zhou watched this scene with great interest. While Niu Decai arranged the light source, he rehearsed the appearance of the finished photo in his mind.

He whispered secretly.

"Don't think about it, the face is overexposed!"

Only then did Niu De stand up from his chair.

"How is it? Is it the same as that photo?"

Several students gathered behind the camera raised their heads and looked at Niu Decai strangely.

"Teacher Niu, this frontal view is overexposed. You can only see a ball of white light and nothing else!"

"What? Impossible?"

Niu Decai walked towards the camera with a question mark on his forehead. When he saw the photo, he also fell silent, touching his chin with a thoughtful look on his face.

After a while, among the students' distinctive expressions, Niu Decai showed an expression of sudden realization.

"This is simple, I just need to lower the brightness of the flash!"

"Pfft..." Bai Zhou couldn't help laughing, which attracted the attention of everyone in the laboratory.

Niu Decai frowned and said coldly.

"Teacher Bai, please don't disturb my class with the students. If you can't control it, please leave the laboratory!"

When Bai Zhou heard this, his face instantly darkened.

"Teacher Niu, what you said is a bit excessive. This is my office!"

If it weren't for the students' face, Bai Zhou wouldn't care about him.

Niu Decai seemed to have been greatly provoked and on the verge of breaking out, but he still tried hard to calm down his mood.

He said to Bai Zhou.

"Okay, then may I ask why Teacher Bai is laughing in my class? Are the classes I teach so interesting?"

Bai Zhou shook his head disapprovingly.

"No, I'm just a little confused. Why is Teacher Niu unwilling to accept the opinions put forward by the students?"

"Oh?" Niu Decai said to himself, as if he had heard a big joke.

"A student who has just come into contact with photography is gesticulating in front of me. Are all my years of advanced education fake?"

Of course he would not say such words. After all, he is also a teacher and knows what can and cannot be said.

Niu Decai turned to the student who provided the photo and said.

"Okay, since Teacher Bai asked me, this classmate, please tell me where to place the five lamps."

The student looked at Bai Zhou and Niu Decai and hesitated.

"Teacher, I only know that he used five lamps. The placement of these five lamps... is exactly the question I want to ask..."
