2016 Kanagawa Science Summer
Let's make a camera obscle!

Introduction
On Wednesday, August 10, 2016, we carried out "let's make camera obscle!" at Yokohama City Industrial Technology Support Center. . The capacity was 20 people, but nearly 70 people received a large number of applications, and we decided to make a crying lottery this year due to the materials and space. I'm really sorry to everyone who couldn't attend.

What is the Camera Obskura?
First of all, what is the camera obscle? I told you that. He is the ancestor of the camera and comes from the Latin word meaning "dark room". It has been used for a long time to observe solar eclipse, and it seems that painters used it for sketches.

Learn principles
We had you experience what kind of principle actually it is. As a matter of fact, the hot sunshine every day was the same on this day, but the sky was a little thin clouds and looked whitish, and the camera Obskura had a slightly disappointing sky. I was worried that it would be reflected on the wall of the room well, but the upside down scenery was reflected on the wall and ceiling. While observing, I was able to experience the moving scenery, such as a car just entering the rotary or passing the seaside line.

Let's make it
Well, in the second half, I finally got a camera obscle. It is assembled with familiar materials such as milk packs, compact mirrors and sheet-type loupes. It is very difficult to make an inner box that fits perfectly with the milk pack that hits the outer box, and the point of the work is to make the focal length matched so that the surrounding scenery can be reflected neatly. But they all made it well and finished it coolly.

Yeah
At the end, we ran out of time and broke up in a hurry, but thank you very much to everyone who participated.
