Alchemy workshop

Harvey uses the enchantment platform to carefully study the magic crystal that can be "photographed" from Kenneth. This time, he is much more cautious. There is only one special magic crystal at present. If Harvey accidentally damages it, he needs to go to Norton, the capital of the Kingdom, to buy it. Moreover, because there are too many popular magic crystals, he may not be able to buy it.

"Are these Mr. Randolph's gifts?"

The enchantment stage activated the magic crystal and projected a dozen "photos" around it. Seeing these photos, Harvey understood why Kenneth didn't pay so much attention to the function of magic crystal. The projection function of magic crystal is very excellent. Even so, it can't be 100% real. There will be illusory feeling of light and shadow in material projection. The photos of magic crystal inherit this shortcoming. The photos look very illusory and the visual effect is extremely poor.

"I don't think there's any lens or film in the world... Harvey shook his head with a wry smile, trying to make a magic camera is more expensive than he thought. In his last life, he was not a photography related person, and knew little about photography. If he knew the lens parameters or principles, he would be confident that he could make lens and other substitutes.

The projection photos are all records of horses, which are taken from all directions and corners. In the photos, the lines of the muscles of the horses are particularly clear, and the explosive force of the uplifted muscles can be clearly felt. They are all materials used by Kenneth to make the unicorn magic projection.

By comparing the photos, Harvey carefully observed each enchanted magic array structure of this special magic crystal and judged its effect on the influence.

"We should be able to find a substitute. Magic crystal itself is a whole like a camera. It already has the basic photographic function. Maybe we can adjust the photographic effect by adjusting the magic array." Although the principle of photography is the same, magic crystal has nothing to do with the composition of the camera. The camera is based on continuous photography to form a coherent picture.

Magic crystal is said to have been developed by ancient casters according to the function of human eyeballs. At that time, magic was almost omnipotent. Magic crystal was invented based on the casters' understanding of human eyeballs. It has a magic array with similar functions. The image of magic crystal "seeing" will be stored in the special material inside magic crystal, Later, when you want to project these pictures, the magic array will directly project the pictures recorded in the special material.

Harvey controls the enchantment platform to continue to analyze the internal structure of the magic crystal, and he gradually has the bottom of his heart about this magic crystal.

"Ordinary magic crystal can sense the light reflected by material without dead angle of 360 degrees. This magic crystal is only slightly improved to form a lens, which is more like a technological retrogression. No wonder Kenneth said that this thing can only be used in a few cold areas."

In the evening, Harvey takes time out to eat Sherry's dinner, and then tells her to make some pastries that can satisfy her hunger, with more portions, so that when he feels hungry in the alchemy workshop, he can eat them immediately.

After a whole day's research, Harvey felt as if he had found something and didn't understand anything. He was a little frustrated and lay on the cold floor thinking: "it's very necessary to recall the physics knowledge of junior high school, the principle of camera, and remember that it's pinhole imaging. The most important thing is the calculation of image distance. There's a formula."

Harvey regretted giving all the knowledge of nine-year compulsory education back to the school. He racked his brains and couldn't recall a little bit of physics knowledge. Instead, he remembered the appearance of the physics teacher.

"As long as you learn mathematics, physics and chemistry well, you are not afraid to travel all over the world. This is a wise saying!"

Harvey doesn't intend to give up easily. Although most of the technology trees or magic trees in the world are ordered by casters, and the knowledge and technology that ordinary people have developed is limited, there must be someone who has studied such a simple thing as pinhole imaging. The source of his confidence is the instrument used to test myopia when he took Shirley to an optical shop to match glasses last time.

At this point, Harvey does not continue to study blindly, quits the wizard's tower, takes a bath, enters the meditation state, and restores the mental power consumed by operating the enchantment platform.

The next morning, after a long search, he finally found a book recording the principle of pinhole imaging in the corner of the Elroy library, in which all kinds of experimental data were recorded in detail. This book was classified as biology, belonging to the study of human eyes. The principle is not complicated. With the research data of this book, Harvey directly started to calculate the image distance and recall modern knowledge for experiments.

His goal is to make a camera, which can directly and clearly project the image on the white cloth. It's not difficult to achieve this effect by using magic crystal, and it's a lot easier to study.

For several weeks after finding the direction, Harvey's research made new progress every day. Based on the magic crystal, the magic array was constantly improved, and the photographic image was clearer. When the image was projected, it was no longer out of thin air, but could be projected onto the white cloth to form a clearer image.

······

In the dim room, the doors and windows were closed, and only a weak oil lamp was lit.

Harvey sat in his chair and nervously looked at the wall in front of him, where a piece of white cloth was fixed. If you look at its shape and size, you will find that this piece of white cloth is actually a table cloth. Next to Harvey, there is a wooden box about the size of a palm. The dim light comes out of a round hole in the wooden door. When Harvey puts his hand on the wooden box, the dim light from the hole begins to come to an end. The light is brighter and forms a clear image on the white cloth.

Shirley, the maid, sat quietly beside Harvey and watched the countdown of white cloth.

“3。”

“2。”

“1。”

At the beginning of the film, there is nothing special. Just like the first documentary film on earth, it simply records the scene of a maid preparing breakfast.

Harvey's nose is a bit sour when he sees the picture that he has not seen for a long time. Although the projection picture is not as clear as the cinema, which is at best the level of the school projector, the film is colorful, and the coherent picture looks no different from the modern film. This has been a great success, spanning half a century of modern people on earth.

Shirley was also surprised to see the familiar and strange figure of white cloth. She had never seen herself preparing breakfast with such a strange vision. Cherry lips opened slightly in surprise and asked curiously, "master, this is..."

Harvey, who has been surrounded by a sense of achievement, split his mouth and laughed brightly: "although the research results of my period of time are still far from perfect, there are still many areas for improvement in photography and storage."

She knew what Harvey was studying, and there was a strange space in Harvey's bedroom wardrobe. Harvey had already moved his bedroom in. She could not help laughing when she saw Harvey's joy. Her delicate eyes were bent into crescent moon.

Shirley's quiet smile made Harvey's heart beat a little faster. Then he turned on the camera's photography function and came to Shirley. He bent over, stretched out his right hand and said with a smile, "Miss Shirley, for more research materials and to celebrate this success, can you dance with me?"

"Will it all be recorded?"

"Of course, it'll take pictures of every movement we dance."

Shirley puts her catkin on Harvey's hand. Harvey gently kisses the back of her hand and pulls her up. In Shirley's exclamation, she can dance the world's ballroom dance at will. The dance steps are not very complicated, but Shirley's movements are clumsy and can't keep up with Harvey's rhythm.

Driven by Harvey's body, Shirley's pretty face showed a look of panic and said, "master, wait, my glasses haven't been taken off yet, ah."

Said has stepped on Harvey's instep, Jiao body lost the center of gravity, was Harvey into the arms.

When they looked at each other, they both chuckled, adjusted their movements and danced happily again. Harvey didn't feel so happy for a long time. Even when he finished count of Monte Cristo, he didn't feel so successful.
