"Knock knock!"

When Jonghyun opened the door, he saw Wong Tae-ka and Yoon-a standing in front of the door, holding all sorts of things.

"Oba!" Yuna looked at Jonghyun and suddenly blossomed. When Zhong Xuan saw Yun'er, he also smiled dotingly, and stretched out his hand inside: "Come in!"

Wang Taika also smiled: "Ah, Zhong Xuanxi, see I didn't lie to you!"

"Come in and sit, there are so many things, do you want me to help?" Zhong Xuan welcomed the two people in, and the room was very well cleaned up at this time, clean and bright.

Wang Taika put the tray of barbecue and said, "I didn't help, I just ate some together, and I was happy." By the way, I also have a documentary here, so I'll watch it later. Is there anything that can be shown at home by Zhong Xuanxi? I have a portable hard drive, and the USB port of a normal computer is fine. ”

"Absolutely. Jonghyun opened the TV series, then connected to his computer, and said, "I don't usually watch it often, I'll study it first." ”

Wang Taika smiled: "It's really disturbing." ”

"No, no, no. Zhong Xuan said this in his mouth, but in his heart: You still know that it is an interruption!

The barbecue thing is very fast, and you can start directly when you prepare the things, and eat while roasting, this process is actually more interesting.

But just barbecue is also easy to be greasy, so Wang Taika made two cold dishes, that is, shredded potatoes and cucumbers, which are not high in technical content and are super suitable for Wang Taika. Even in order to prove to Yun'er that he can cook, Wang Taika specially fried a plate...... Scrambled eggs!

That's all there is to eat, and there is no way to make it simple. The rest is meat that needs to be grilled and things like that, as well as lettuce. Wang Taika was still worried about the seasoning, but it happened that Zhong Xuan had it at home, which was even more beautiful.

Yuna is very happy, one is a good parent, and the other is a good ...... Bastard Seventeen!Anyway, it's fun, and there's no such thing as multiple light bulbs. The blessing of life is nothing more than a time to eat something with someone close to you and have fun.

"Why don't you drink something?" Yuna suggested.

Wang Taika smiled: "I really can't drink yet, and I don't have anything." ”

Jonghyun set up the TV, listened to their conversation, and said, "I have it in the refrigerator, and I didn't finish it at yesterday's party." If you want to drink it, take it and drink it. There's juice in it, Yun'a, drink it. ”

"Do you drink?" Wang Taeka asked Zhong Hyun with a smile.

Zhong Hyun was already depressed, thinking that it was already like this, and it would be okay to drink some. So Zhong Xuan nodded: "A little bit is fine." ”

Wang Taika clapped his hands: "OK! Actually, I don't particularly like to drink, but since we have a dinner together, this is a small dinner, so let's drink some." Otherwise, I always feel that there is no atmosphere. ”

"I'll go get it, I've got it here, find it yourself if you want to put it." After Zhong Xuan finished speaking, he went to the refrigerator to get wine.

Mrs. Wang stuck to the computer in front of the TV, connected the hard disk, and looked for it from inside. Yun'er was very curious, so she also came over and looked next to Wang Taika.

"Wow, that's a lot!" Yun'er looked at the catalogs, there were many names in them, all of which were labels in Chinese.

"It's just part of what I was looking for in the first place, it's really somewhere else. Wang Taika flipped through it with a smile, and to be honest, it was really quite a sense of accomplishment.

Yun'er looked at the folders above, pointed to a folder with a starry sky pattern, and asked curiously, "What is this?"

"This folder is full of time-lapse photography, which is very interesting. Wang Taika sighed: "It's still troublesome to shoot this thing and make a documentary." ”

Yun'er asked curiously, "What are you doing?"

"Time-lapse photography is a time-compressed shooting technique, which is to shoot a group of photos or videos, and then compress the process of minutes, hours or even days and years into a relatively short period of time and play it back in the form of video through photo series or video frame extraction," Wang explains. In a time-lapse video, the process of slowly changing objects or scenery is compressed into a short period of time, presenting a strange and wonderful scene that is usually imperceptible to the naked eye. It is usually used to shoot urban landscapes, natural landscapes, astronomical phenomena, urban life, architectural manufacturing, biological evolution and other subjects. This is the most amazing and pleasing way to shoot. But the process was so lonely. ”

"Hmm!" Yun'er nodded: "You said a big push, I didn't understand a word." ”

"Haha, you'll know when I get the contents of the hard drive into the computer and play it. It is easy to freeze when playing directly in the video. "Actually, the process of shooting time-lapse photography with a machine is similar to making stop-motion animation, where a single still picture is connected together to get a dynamic video. Time-lapse time-lapse shooting for a long time. Therefore, it is also called low-speed photography or time-lapse stop photography. At the heart of this is the means of recording and reproducing the slow process of change of scenery in timed and intermittent changes in a clearly changing image. For example, it takes about three days and three nights for a flower bud to open, which is 72 hours. We photographed one of its frames every half an hour, recording the subtle changes in the flowering movements in order, and shot a total of ...... Uh, that'......"

Yun'a smiled and said, "One hundred and forty-four." ”

"Yes, yes, smart! A total of 144 frames, which are then projected through a projector at a normal frequency, 24 frames per second, in six seconds, to reproduce the flowering process of three days and three nights. You've seen that kind of picture, right?" asked Wangtaka.

"Oh, I see! I know, I've seen it, but I don't know the exact name. Yun'er suddenly realized: "Very good, you are a good teacher." ”

Wang Taika said nonsense: "Well, come to my house tonight, and I'll make up for you!"

"Hey!" Yun'er scolded Wang Taika, very helpless, but she couldn't help laughing: "Bad guy!"

"Haha, okay, do you want to see it? urban or landscape?" asked Wang Taika.

Yuna thought for a while: "Can't you watch them all?"

"Of course you can, I'm asking you which one to look at first?" Wang Taika smiled helplessly.

"Scenery!" Yuna asked, "What kind of scenery is it?"

"That's the Northern Lights in the Arctic Circle! Didn't I tell you before, I was a temporary photographer for National Geographic! I approached a Finnish team that specialized in time-lapse photography, and I got the opportunity to join in. Wang Taika smiled and clicked on the folder and said: "The first four are the Northern Lights and starry sky taken in the Arctic Circle, and the latter ones are the glaciers photographed." Want to see it?"

Yuna nodded: "Of course!"

"Okay, play. Wang Taika was just about to play, but he remembered something and said, "It's interesting to watch this thing together." Jong Hyun Xi, I ask you to enjoy the beautiful scenery!"

Zhong Hyun held a few cans of beer and looked at Wang Taika and Yuna with an inexplicable expression: "What?"

"Don't do anything, sit down first. Wang Taika went over and closed the curtains, then returned to the computer and said, "A magical scene is about to happen!"

Wang Taika pressed the space bar button, and then the computer started playing, and the TV connected to the computer also began to show the picture.

In the darkness, the stars were dotted in an instant, and the whole picture was suddenly chilled by thousands of stars, accompanied by the faint green Northern Lights, a shocking and gorgeous scene was presented in front of everyone.
