The burly man with the number 56 stared at Jiang Yuan intently.

Jiang Yuan adjusted his glasses and continued.

Photoshop is a very interesting software.

Girls really like it.

It has a wide range of applications, mainly because of its high degree of freedom and depth.

The stories derived from it can be described as "from beginner to giving up", which is a good description.

Of course, ordinary consumers usually only come into contact with its entertainment side, such as retouching photos, changing scenes, and spending an afternoon to post on social media, or spending half an afternoon to make it go viral.

If you are willing to spend a whole night, you can usually graft a celebrity's head onto the body of a strange animal.

Or reshape a batch of wedding photos, making the bride and groom and their friends feel like they are attending someone else's wedding.

But on the dark side of entertainment, Photoshop can also be very cruel.

It can be used to forge official seals, and if used well, it can result in a prison sentence of up to three years.

It can also be used to synthesize photos for extortion. In Hunan's Shuangfeng, it has developed into an industry specifically targeting officials, with far-reaching effects.

Of course, it can also be used to solve cases and greatly increase the difficulty of solving them.

In the fingerprint battle across the province, Jiang Yuan used LV4's Qingdao-style fingerprint analysis method, paired with LV3's Chongqing-style fingerprint analysis method, and the skill of image enhancement, to achieve great success.

Continuously solving major and accumulated cases actually means that Jiang Yuan's fingerprint identification skills far exceed the average level of provincial experts.

Now, the fingerprints he encounters are beyond the normal level of difficult fingerprints.

"Difficult fingerprints can often bring surprises when processed with Photoshop. Photoshop, or PS, is the key software we use in criminal investigation. Its focus is to ensure the accuracy of images and to have certain rules when making modifications."

While Jiang Yuan was speaking, most of his attention was still focused on operating the software.

Practical explanations come first, and explanations come later.

Chen Wenming straightened his back and watched Jiang Yuan's operation for a while. Slowly, he adopted the same posture as Cao Keyang, lying back.

When you look at something in a different way, your emotions and sense of achievement are different.

Just like Cao Keyang, at the beginning, he watched with a straight back, which made him very uncomfortable.

But when he lay down and watched, it became much more comfortable.

Cao Keyang's suppressed emotions were released, and at some point, he even had a gentle smile on his face.

"A group of people watching with relish." Chen Wenming looked around and saw that all the forensic investigators were lying down, unable to help but sigh: high-level technology greatly reduced everyone's enthusiasm for learning.

A forensic investigator from the district bureau heard Chen Wenming's words and disagreed. He looked at the screen and said, "Captain Chen, you have to look at it from a different perspective to find it interesting."

We are "pawread.com", find us on google.

"What perspective?"

"For example, I never knew that fingerprint identification could reach this level. It's like a magical skill." The forensic investigator from the district bureau was a little younger than Chen Wenming and spoke in a calm tone.

Chen Wenming still shook his head and said, "Dragon-slaying technique."

The other forensic investigators didn't care and said, "As long as it looks cool. In the future, when my nephew asks me what I do all day, I'll have something impressive to say. I can't just talk about how awesome things are on TV every day, reality is not like that."

Cao Keyang nodded in agreement. In his heart, he naturally hoped to become such an expert in identification, but it was inappropriate to say such things in front of colleagues, especially superiors.

He couldn't do it himself, but it was a kind of joy to boast about his colleagues.

Jiang Yuan is also considered their colleague now.

Chen Wenming knows better than anyone how difficult it is to achieve Jiang Yuan's level of fingerprint identification skills. The skills of Photoshop are equally tedious and require knowledge of mathematics and other related fields.

Therefore, Chen Wenming sighed even more: "After so much effort to organize this training, all they see is how handsome he is."

"There are plenty of opportunities for training, no, I mean, opportunities for learning. That's what training is all about." Another forensic investigator quietly joined the discussion.

On the podium, the specific technical details were no longer of much interest to everyone.

Some things, if you don't understand in the first class, don't expect to catch up in the second class.

However, everyone still had a keen interest in the advanced methods and capabilities of fingerprint identification.

So at this moment, there were more whispers and quiet conversations in the audience, but everyone's smiles also increased.

Seeing that the forensic investigators next to him were all against him, Chen Wenming had nothing more to say.

In fact, discussing the cutting-edge abilities of a technology and discussing its boundaries is a training mode in itself.

Just like fingerprint technology, now that it has the ability to extract fingerprints from clothing, bedsheets, and other places, various means must be used to inform frontline police officers. Otherwise, what's the use of conducting research in the laboratory without the operations of frontline police officers?Similarly, fingerprint collection training is conducted by various units every year to strengthen training and improve the understanding of grassroots personnel.

The advancement of DNA is more obvious. In the early years, DNA identification could only be done with blood, saliva, human tissue, and **. It was not until around 2008 that sweat was promoted in many places. In another 10 years, the updated knowledge of basic police officers would be that any place the suspect has come into contact with can be tested.

Today's training was originally attended by everyone for fingerprint identification learning, so the first class was quite disappointing.

However, in the second class, more and more people started to treat it as a cutting-edge lecture, which became very popular.

After all, those who usually give cutting-edge lectures are often not at the cutting edge themselves.

What Jiang Yuan demonstrated today was considered beautiful in the eyes of a group of forensic police officers.

"Well, let's run it again after processing," Jiang Yuan said, referring to the processed fingerprint image.

The forensic officer in the front row couldn't help but laugh, "It doesn't look like it at all."

"In fact, the two images are exactly the same. This can be directly proven. If the suspect's lawyer raises this point, we can do forensic identification... Do you want to do it? It may take about ten minutes..." Jiang Yuan politely replied, and anyone who had an opinion would be answered attentively.

But the forensic officer in the front row waved his hand, "Don't mind me, just follow your teaching outline."

Jiang Yuan actually didn't have a teaching outline, but seeing that the forensic officer wasn't particularly interested, he continued, "Then I'll continue. Now we need to mark the characteristic points again, and this time, we should choose a smaller area..."

"The specific area to choose should be judged based on the finger shape."

"We have already dug out two cases, and we have two sets of fingerprints for reference. From here, we can actually see some of his hand habits."

"Well, we can actually use some footprint identification thinking here..."

Jiang Yuan mentioned it briefly and didn't say much. After all, today's lecture was about fingerprint identification, so it was better not to digress too much.

However, Chen Wenming couldn't help but sit up.

He usually uses footprint thinking when doing fingerprint identification.

It was a natural choice. A person has 10 fingers - a normal person. And in terms of usage, there are always some habitual movements, different operating methods, including whether they prefer to use their left or right hand, single finger or two fingers, index finger or middle finger, or middle finger and ring finger, and so on.

But unlike the development of footprint identification, there are no standards or rules for fingerprint usage habits.

Everyone figures it out on their own.

Chen Wenming was also figuring it out, but he didn't have many opportunities to use it.

At this moment, he wanted to hear Jiang Yuan's opinion.

Although the Dragon Slaying Technique was in a state where there were no dragons to kill, it would be great to absorb the essence of the Dragon Slaying Technique and apply it to slaughtering cows and sheep.

However, Jiang Yuan did not continue to talk about the fingerprint footprint thinking.

Because the characteristic points of the fingerprint had already been marked, sending it to the fingerprint database for comparison would quickly yield new results.

"After processing it like this, comparing it with the existing fingerprints will easily yield results. Because it is an assignment system, after processing with Photoshop, its assignment value can obviously be improved..."

Jiang Yuan began to explain the key points.

The forensic officers below were already anxious, and someone shouted, "Make a call first, make a call first!"

"I'm dialing now." Jiang Yuan took out his phone from under the table and said, "This is not urgent. He's in prison."

The call connected, and Jiang Yuan reported the situation to the captain on the other end, who naturally expressed his gratitude and joy.

Even though the person was in prison, the case was considered solved.

Moreover, the suspect would continue to be prosecuted and sentenced, saving time and energy for the arrest.

Jiang Yuan suggested continuing to dig into the case and then hung up the phone.

The forensic officers in the audience were filled with admiration.

Especially the last part, it was like a dream.

Normally, when the captain of a regular police station receives a suggestion, they would chew it up and spit it out along with the person who made the suggestion.

Jiang Yuan was a bit accustomed to the politeness of the captain from another county, but seeing the expressions of everyone, he quickly changed to a more serious look and said, "Let's continue the course..."

Buzz...

The vibration of the phone rang again.

Jiang Yuan glanced at it and hurriedly explained, "It's a call from Miaohe County. I don't know if there's any unexpected situation. Let me answer it."

After speaking, Jiang Yuan answered the call.

In the earpiece, the voice of the captain of the Miaohe County Police Station was deafening, "Jiang Yuan, thank you so much. We've already caught the person."

"That's great, congratulations."

"It's congratulations to all of us. Thanks to you, this case that was considered closed has been revived."

"Has the suspect confessed?"

"Not yet, but it should be soon. We found some evidence at his house, and there's no problem with zero confession. Confession is just a matter of time." The captain of the Miaohe County Police Station chatted for a while before hanging up the phone.Turning around, the room was filled with trace evidence investigators, their eyes gleaming with excitement.

A long-lost passion was reignited, each person fantasizing about being the one to make the call.
