Secondly, he wanted to compensate Xie Xiaoya. During this time, Xie Xiaoya has been hiding from herself, and letting her take pictures is an affirmation and encouragement to her. He believed that Xie Xiaoya would appreciate it.

After all, there are still many places where she will be needed in the future.

Onlookers also felt that Xie Xiaoya was the most suitable for taking portraits.

No matter her appearance or temperament, she is the only one in the whole yard.

She is like a crane standing in a flock of chickens.

After Xie Xiaoya retreated to the gate of the hospital, the whole person was completely presented in the camera.

Zhu Xiaohua motioned for her to take a few steps back, filling the entire shot.

When Xie Xiaoya stood up and paused, Zhu Xiaohua was surprised again. Xie Xiaoya in the shot, her skin is white and tender, and even the tiny pores and dark purple blood vessels on her face are faintly visible.

He had to sigh that this giant camera was simply amazing.

The portrait you see from the camera is a hundred times clearer than what you see with your eyes.

He could even see the white shirt inside her woolen jacket, and the white underwear looming behind the shirt.

Under this giant camera, the characters seem to be three-dimensional and transparent, and Xie Xiaoya's slightly curved eyelashes and red mouth lines are all presented one by one.

At this time, a middle-aged woman passed behind Xie Xiaoya, her face swept past the camera, and Zhu Xiaohua clearly saw the dirt on her nose. The pores of her nose were full of gray dirt, and under the hair on her forehead, there were layers of white dandruff.

Compared with the two, Xie Xiaoya seems even more commendable.

The problems of that middle-aged woman did not exist in her.

In her pores, there are neat hairs, shaggy and very cute.

Zhu Xiaohua settled down, fine-tuned the lens into place, he rotated the lens 90 degrees, and then quickly pressed the shutter. There was a soft "click" and the shooting was complete.

This time, Xie Xiaoya took the lead in running over, together with the students, waiting for the photo paper to slowly confide.

On the photo paper, Xie Xiaoya herself is lying flat on the photo paper, which is completely different from the landscape painting just now.

"No, is it a mistake, why isn't the character upright?"

A student asked while pulling a photo paper.

Xie Xiaoya also had questions, she was standing just now, but she was lying down in this photo. Could it be that there is something wrong with the camera?

With doubts, she pulled out the photo paper little by little.

With the soft sound of "purring", the photo paper was spit out. On the photo paper, Xie Xiaoya is indeed lying down, and there is nothing wrong this time.

It was exactly 90 degrees away from the one he was standing on.

"Brother Zhu, is it a mistake, or is the camera wrong, why is the photo taken in reverse?"

The students asked.

Zhu Xiaohua smiled: "You turn the photo paper upside down ninety degrees to see." ”

The width of the paper is only one meter, but the length is one meter eight. If you want to take a complete picture of Xie Xiaoya's full-body portrait, you need to turn it upside down.

How to reverse?

One way to do this is to turn the person upside down, for example, if you want the person in the photo to stand, you have to have the person lying on the ground while taking the photo.

Another way is to reverse the camera, that is, the original standing upright character is filmed sideways.

This is another feature of this giant camera.

It was Zhu Xiaohua and Professor Shao who had already discussed, and it was the same as the horizontal and vertical shooting of the camera in the future.

With the addition of this function, long forms of photo paper can be used to the fullest.

On the one-meter-eight photo paper, Xie Xiaoya's portrait is complete, and her height of one meter and six is clearly ingested from head to toe.

These students took the photo paper and turned it upside down, first turning Xie Xiaoya head down and feet up, and after finding that something was wrong, they poured it down one hundred and eighty degrees again.

This time, Xie Xiaoya on the photo paper stood upright.

In the photo, she is smiling lowly, and every part of her body is presented in three dimensions, even clearer than looking at her with her eyes.

Everyone looked at such a large photo, every detail was vivid, and they couldn't help but admire.

At this time, Xie Xiaoya found that in this photo, the left side is dark, the right side is light, and even on the right arm, the clothes outside are hidden and seem to be invisible. The arms blend with the white photographic paper behind them.

Others were quick to find out about the problem as well.

"Brother Zhu, why is the color dark and light on one side?"

Xie Xiaoya asked.

Zhu Xiaohua took a closer look at the photo and found that the color was indeed a little uneven.

The first landscape photo is uneven in color up and down. This vertical photograph is unevenly colored on the left and right.

Zhu Xiaohua put down the erected photo and found that the two were the same problem, that is, the top half of the photo was lighter and the lower part was darker.

He took a third photo according to his guess, and this time confirmed, the guess was true.

Why is this happening?

Zhu Xiaohua discussed with the three students.

One of the students in charge of the mechanical design part said: "Could it be that the photo paper is not well fitted, the upper part is tighter, and the lower part is loose?" ”

He took the camera apart and started overhauling it again.

The student in charge of the optical lens said, "Could it be a problem with the lens, if the lens is not thick, it will cause this situation." ”

According to his guess, it may be caused by overexposure of one part of the lens and underexposure of the other.

In most photos, different shades of color are an issue of exposure. The exposure time is too long, and the colors are darker. The exposure time is too short, and the colors are lighter.

Everyone started from their own professional field to find problems.

Zhu Xiaohua looked at the potion on the back of the photo paper.

He held a piece of paper upright against the wall, and the moment the paper stood upright, the potion in the plastic bag on the back shifted and fell back to the bottom due to gravity.

The potion that used to be evenly distributed instantly became more and less at the bottom.

The photographic paper is also distorted. The bottom is bent due to the pressure of the potion.

Zhu Xiaohua was cheerful.

Zhu Xiaohua said: "I don't think it's the camera's problem, it's the paper's problem. When the photo paper passes vertically through the camera, the potion on the back becomes uneven, with less on the top and more on the bottom, so the color of the photo will be light on the top and dark on the bottom. ”

The students stopped what they were doing and started working on the paper again.

A one-meter-wide potionary bag, when upright, all the potions are concentrated at the bottom. The top is almost empty.

How can I make the potion stand upright and still be evenly distributed?

As long as it can be evenly distributed, the problem of different shades of color in the photo can be solved.

Zhu Xiaohua thought of the striped bag.

A tool that divides a large plastic bag into countless small bags.

Divide a large bag into ten long bags arranged in parallel and connect the bags to each other, and the problem can be solved.

What's more, you can directly divide the large bag into countless small squares, and fill each block with potions, so that it can defy gravity and not rush to one place after being erected.

Zhu Xiaohua told the students about his idea, and they evolved it a little on it, and finally submitted a formed idea to the factory.
