Chapter 540 Marks on Anonymous Photos

Han Xu continued to talk, "Digital cameras use electronic photosensitive elements to create images. What they do is use numbers to simulate the colors they feel, so the colors are always bright.

As you can see, the characters and scenes in this photo have thicker colors, and they were obviously taken with a film camera.

Also, the post-processing space of film is smaller than that of digital photos.

The film's imaging and storage format and other load-bearing properties determine that its spatial range for manual correction in the later stage is very small.

In other words, it is more suitable as evidence!

Because it is too difficult to modify, but unlike digital photos, even ordinary people can handle it with Photoshop.

All in all, digital photos have more convenience and timeliness. They are simple and direct in beauty, while film with a sense of age is more inclined to display delicate emotions, and its beauty is more subtle and real. "

At this time, Miao Xiaolan, who was confused, couldn't help but interjected, "Han Xu, the more you talk, the more confused I become. Does this have anything to do with the case?"

Han Xu didn't mind at all. He smiled and said, "Team Leader Miao, don't underestimate this. Maybe it can be a breakthrough?"

Miao Xiaofeng heard this and asked first, "How do you say this?"

Han Xu paused and continued, "Team Miao, if this photo was taken by an old-fashioned film camera, it will still be helpful to us in finding the person who took the photo."

When Zhang Yao heard this, he immediately understood, "There are not many people playing with this kind of old-fashioned camera now. Let's check it out."

After being reminded like this, Zhou Hai nodded frequently and said, "Yes, why didn't I think of that? As expected of Officer Han, he is indeed amazing. I admire him."

Han Xu, however, didn't take it seriously and pretended to be surprised and asked, "Didn't you find the person who took the photo?"

Zhou Hai and Zhang Yao shook their heads together after hearing this.

Miao Xiaolan became even more curious, "You didn't find the person who took the photo, so where did the photo come from?"

Zhou Hai replied, "The photo was anonymously mailed to the City Department a few days ago. We have investigated it and have not found the person who took the photo or the person who provided the photo."

This is said very strictly.

Miao Xiaolan frowned, "So that's the case. That's strange. Why did the person who took the photo do this? And who is this person?"

As soon as these words came out, several people present were stunned.

Zhou Hai was the first to break the silence, "At first, when we received this photo, we didn't take it seriously, but Captain Lin just took one look at it and took it very seriously and asked us to thoroughly investigate the two people in the photo. . That’s why we found Chen Chunsheng’s head.”

"What about Li Yongmei?" Han Xu immediately thought of another particularly important clue.

Zhou Hai glanced at Han Xu in surprise. He didn't expect that the other party's mind would jump so fast. He replied in detail, "We couldn't verify Li Yongmei's identity through the photos, but it's a coincidence. Xizhi Police Station There happened to be a human trafficking case over there, and one of the people rescued happened to be Li Yongmei! "

When Han Xu heard this, his brows instantly raised, as if he had caught something, "You mean, besides Li Yongmei, there are other victims?"

Zhou Hai nodded numbly and said, "Well, there are probably three or four more."

"Have you caught the human traffickers?" Miao Xiaolan was more concerned about the traffickers who had suffered tens of millions of dollars.

Zhang Yao replied, "I caught it, but..."

When Han Xu saw Zhang Yao's hesitant expression, he immediately understood, "Is Li Yongmei different from others? She has changed hands several times?"

Zhang Yao didn't expect Han Xu's thinking to be so sharp, and he caught the key point immediately, so she nodded and replied, "Officer Han is right, the trafficker couldn't tell how many hands Li Yongmei was transferred to, but it was in his hands anyway. It’s almost beyond torture.”

In fact, this situation is very rare!

Generally, trafficking cases involve people being trafficked from one place to another remote place.

It's really weird that someone like Li Yongmei, who was changed hands several times, actually returned to Yancheng.

It's as if there is a big hand in the dark, controlling everything.

However, Han Xu didn't say much, but returned his attention to the photo.

Zhou Hai said before that Lin Tianjun only became alert after seeing this photo!

That's strange!

Could it be said that Lin Tianjun knew Chen Chunsheng?

Just like what Chen Chunsheng said: a tiger father has no dog?

What are the connections between their generations? !

Han Xu was a little unsure, but other than that, this anonymous photo was very ordinary, with no obvious marks.

Obvious mark?

Han Xu was shocked. There was no obvious mark. Could it be that there was some hidden mark?

As soon as he thought about it, Han Xu couldn't help but turn over the anonymous photo and start tinkering with it carefully.

When several people present saw Han Xu's appearance, they suddenly became confused.

Especially Miao Xiaolan, but she soon thought of the reason why Han Xu did this.

“Is there anything weird about this photo?!”

Zhou Hai and Zhang Yao had checked the photos before and found nothing strange. At this time, they both looked at Han Xu curiously, wondering what medicine he was selling in his gourd.

As the captain of the Criminal Investigation Brigade, Miao Xiaofeng was naturally much calmer. He just looked at Han Xu for a moment, expecting this guy to stage a moment of witnessing a miracle!

However, after tinkering for a long time, Han Xu did not get anything.

"Haha, sorry, maybe I think too much."

Han Xu had to put down the photo and smiled awkwardly at everyone.

Zhou Hai and Zhang Yao did not care, but Miao Xiaolan did not forget to mock, "How about it, you hunt geese all day, and finally got blinded by geese?"

Miao Xiaofeng felt that this was a bit heavy, and glared at Miao Xiaolan fiercely, just about to say something.

Han Xu did not care, and smiled, "If you often walk by the river, how can you not get your shoes wet? I'm used to it."

Zhou Hai and Zhang Yao did not expect Han Xu to be so picky and put down, and they admired him even more.

Miao Xiaofeng smiled and shook her head, secretly saying, "Young people nowadays, tut tut."

Han Xu was actually still a little unwilling to give up, and picked up the photo again, and then took a look out the window for some reason.

Oh, good guy!

With just one glance, he saw something amazing!

When Han Xu talked about the difference between film and digital photos, he didn't mention one thing, that is, the details of film are more accurate than those of digital.

To put it simply, the details of the black and white parts of the film screen will be preserved, so that the details of the entire screen are directly maximized.

The details of the black part can only be seen after the white part of the digital photo is overexposed.

At this time, facing the sunlight outside, wow, the black and white contrast.

In the upper right corner of the photo, there is a very small English letter!

Another capital "Z"!
