Chamber of obscura do it yourself at home. How to make a chamber-scope with your own hands: two detailed lifehak. Guidelines for work

Already known for several hundred years of humanity is a prototype of a camera. In this article, we will not only get a closer look at her story and the principle of action, but also we will analyze how to make a chamber-obscure with your own hands from girlfriend in several ways.

What is the camera-obscura

Chamber-obscura (lat. camera - "room", obscura - "darkened, dark ") - the simplest optical device, the prototype of the camera. It can be like a box or a chest, on one of the walls of which a small eyelet is cut, and instead, the screen is stretched from translucent material and a dark room with the same small eye. and screen.

Another name of this device is a Pinhol Camera (English. pinhole Camera - "Camera having a hole").

Principle of camera-obscura

Before making a chamber-scope with your own hands, you need to figure out how it acts. Its work is based on the law famous for the rectilinear spread of light rays. A lot of narrow light beams passes through the camera's opening of the camera. Each of them leaves the light spot on the screen of the opposite wall equal to the sizes of the eye. Such specks from the set of rays are superimposed on each other on the surface of the pinhole chamber screen, thereby creating an optical reflection-copy of the subject or panorama that is in front of this peculiar device.

Human Eye and Pinhol Camera

The camera-obscura, by the way, reminds the principle of its action. Human eye - an image on its screen also falls through a small hole and upside down. It happens from the fact that the light gets into the eye, and in the apparatus at an angle - the rays, reflected from the top of the objects, are directed down, and the rays reflecting the objects close to the Earth are directed upwards. Inside the chamber they intersect, so the image on the camera screen is turned upside down. In our body, a picture in the correct position returns the brain, and in the camera - a mirror.

History of Pinhol Camera

How to make a camera-obscure with my own hands, and our distant ancestors were conceived - for the first time this phenomenon noticed Aristotle in the IV century. BC.

The legendary Leonardo da Vinci was the first to describe the algorithm and the mechanism of its work. His invention in the Middle Ages used artists - camera-obscura helped them make pictures of any objects.

About how to make the camera-obscura in the more "advanced" version, scientists thought and later. In 1568, the principle of operation of the Pinhol-camera was improved - the Venetian inventor de Barbaro replaced the screen with a flat-convex lens. This innovation significantly improved the clarity and saturation of the image. The device was named a wall-camera. It has become a step to a modern camera.

How to make a chamber-scraper with your own hands out of the box

For the manufacture of your own pinhole camera will be needed:

  • cardboard box from under tea or juice;
  • thin translucent paper is perfectly suitable for tracing or parchment;
  • scissors;
  • glue;
  • scotch.

So, how to make a chamber-obscure with your own hands from the box from tea, juice, etc.:

  1. Cut on one of the walls of the box a small window.
  2. Using glue or scotch, creeps the hole with a suitable piece of paper, turning it into the future camera screen.
  3. In the middle of the opposite wall, make a hole with a diameter of no more than 1 mm. Use for this needle, pin, stationery button.

That's the whole instruction, prompting how to make a chamber-scope with your own hands out of the box. Use your invention in a darkened room - visit it on a bright and contrast light source - for example, a burning candle. Its inverted image should be reflected on the paper screen.

How to make a chamber-scope with your own hands: Camera

In this life, we will analyze the creation of a more complex, but more interesting Pinhol-camera, with which you can get real photographs. To begin with, collect the desired materials:

  • aluminum jar;
  • a piece of plastic;
  • matchbox;
  • 2 "barrels" for film;
  • photofill herself 35 mm;
  • black paint, tassel;
  • stationery knife;
  • insulating tape;
  • needle;
  • scissors;
  • line;
  • pencil.

So we disassembled two ways, prompting how to make a chamber-scope with your own hands. In the last better to shoot a tripod, and the shutter is open on a strictly defined time - in sunny weather for 6 seconds, into a cloudy - for 7-8 seconds.

Not that in our time there was a problem in purchasing a camera. Rather, the futility is such an opportunity for almost everyone. Many are content with cameras in phones, many spend a bunch of money for semi-professional or professional cameras, and MNOOOO -OGOs are fond of lomography, which is not only fashionable, but also affordable.

Therefore, of course, the self-made camera is not a forced measure, but an interesting experiment and (which, as it seems to me, even more importantly) the opportunity to do something with your own hands and see the imaginable imagination.

In order to make a chamber-obscura, you need to follow the instructions:

1. Take any container / box / tin can or, as on the illustration, a jar of films, a thin needle, a piece of foil, isolent (black tape) and black and white (!) Photo paper (for example Kodak Professional Polymax II RC) or Slide film (for example Kodak Ektachrome E100 GX).

2. Cut the hole in the middle of the box with scissors.

3. The resulting hole is much larger than the hole of Pinhol.

4. Cut the piece of foil, which is completely (and with a margin) closes the hole.

5. In the middle of a piece of foils. Do minimal hole with a thin needle.

6. The surface of the foil must be smooth, so remove all the irregularities of sandpaper.

The smaller the diameter of the hole, the better the snapshot will be.

7. To avoid light reflections inside the container, its and foil on the inside need to paint matte black paint.

8. Scotch absolute to the foil container.

9. Clay the hole with a piece of tape to protect from premature light penetration.

10. In a dark room (!) Insert the photo paper into the container so that it does not cover the Pinhol.

11. If all the holes are securely closed, the camera is ready for work!



In this article, I will tell you how to make a chamber of a knotter of a matchbox and homemade breeding agents.

It should be noted that such a camera does not have the depth of field, but this does not deprive the photo made by Pinhol Volume, it is not at all, it is soon filled with a picture of his unique artistic atmosphere. The principle of operation is very simple, the light from the shooting object passes through the hole and falls on the photosensitive material, that is, the film, it turns out as if the projection of the image.

What do you need for the manufacture of such a camera

Matchbox

Photowing 35mm.

Some plastic from any bottle

Any aluminum bank

Stationery knife

Empty Bachel from Under Film

Insulating tape

Pencil

Scissors

Rule

First of all, you need to make marking and cut a frame window in the inside of the box, it was 36 x 24 mm, but here you can do the form arbitrarily, as some make 24 x 24 mm to how to like it.

After you cut the recovery window, you need to paint the inside of the box into the black color, you can use any paint, marker or mascara. I used the acrylic paint-spray matte, the glossy did not try, in my opinion it will create not the necessary glare. It can be noted that the edges of the personnel window of the inside of the box tangled, this will affect the photo and give more artistic appearance. If you wish, they can be smoothed with a file or a stationery knife.

How to rewind the frame? Whatever this process could be controlled, the following is done, cut out a thin tape and smoothed fine with your fingers, so it twists. On one of the edges are sharpening.

Coleutented it to the barrel, insert it into the hole in the film, as shown in the photo. It is necessary to fix the plastic ribbon well that it would not jump from the hole when rewinding, it is also necessary to make sure that the film will not break. When rewinding, clicks will be heard, so if you have a frame window with a size of 36 x 24 mm, you need to count eight clicks (for the safety netting nine) and you can photograph a new frame. If the frame window 24 x 24 mm is counted six clicks.

Let's go back to the match box, now we need to prepare an external part, we make markup and in the center cut out a rectangular opening of 8 x 5 mm.

The most important detail of the camera, this is a properly made hole that is responsible for the sharpness of the frame, the less it will be, the sharper the frame. From the aluminum bank you need to cut the square of 15 x 15 mm and the needle gently pierce the hole, be sure to clean up from the opposite side. And if you bring an aluminum plate to the window, the hole must be barely seen.

It is always necessary to paint everything into black, the smaller the light plots will be, the better the frame will be better, it is also necessary to cry the hole in the black marker, so that the rays of the sun were not glad to fall on the metal surface.

We start collecting our miracle camera, tapey, put on the outer side of the matchbox, aluminum blank with a hole, it is desirable to secure exactly in the center, which would be a ray of light throughout the frame. Take another matchbox and make a markup, cut off the rectangle of 15 x 8 mm, cutting the cardboard and attach the tape to our obscura chamber. Another important detail, the shutter itself, the dense cardboard 10 x 30 mm should close the camera hole tightly.

To rewind, you need to make a handle from cardboard and pull the tape, the size of about 5 x 20 mm.

We install the film and fix the inside of the box, and do not forget to check the framework of the frame meter, if you can hear clicks, you can fix everything with a tape.

It is impossible to make light on the film on this isolent, it is advisable to use black, but for the absence, I had to use green, do not save the quality of the pictures on the insulant. Fix everything.

You need to take pictures from a tripod or with a good stop, the slightest chapel smears the frame, makes it fuzzy. (How to make a photo with sharp - read) When photographing Pinchol, you need to be able to determine how to open the shutter on how many seconds, the seconds can be considered to be considered. If the day is sunny and the film with sensitivity then I open four, five seconds, if we are overcast seven, eight. I got a good person from the first time. Try, I'm sure you will not regret.

It proposes to make a miracle invention, known before our era and first described by Leonardo da Vinci. Its dimensions range from the matchbox to huge halls. Camera-obscura translated from Latin means "dark room". The device allows you to transfer real images to the screen. True, here is not enough - in an inverted form 🙂 But it is even more interesting. For many centuries, artists used a commercial camera to create landscapes until scientists invented chemical compounds sensitive to light. So the first photos appeared!

See which masterpiece can be created using a touchscreen camera.

An inverted image of the autumn central park in New York was displayed on the walls and ceiling. Photography made Abelardo Morell with a touchscreen camera. Dimmer the room, "he says," make a small hole for light - and the pictures of the world on the other side of the window will settle in your home.

Um ... - I do not know ... but the idea is seductive 🙂

We can make a simpler device today than that Morlal used. But no less interesting.

We will need:

  • Disposable plastic cup (better dark color)
  • Stationery or pin for sewing
  • Black acrylic paint (can be purchased in bookstores or mix gouache with pva glue 1 to 1)
  • Brush
  • Parchment paper sheet 12 × 12 cm (you can try to replace with cottage or thin white napkin)
  • Stationery
  • Candle + matches, flashlight
  • Small figures or silhouettes for viewing

What to do:

  • Carefully cover a cup of black paint on both sides, let dry the paint

  • In the center of the cup, make a very small hole with a pin or buttons. This will be a touchscreen lens

  • Secure the paper on the cup with a gum. She will serve as a touchscreen camera

  • Light a candle or flashlight, dink the room and watch the light, holding a cup on an elongated hand with a screen to yourself.
  • Consider and you will see a small sickle light spot on a dark paper background - this is an image of a flame, and it "stands on the head"!
  • In front of the flashlight, you can put different silhouettes, experiment with distances and shapes, you can turn the silhouettes, while getting normal images.

Question: Does the eye look like a chamber-obscura? Is it possible?

Finally, a pair of masterpieces from Abelardo Morella 🙂

Bright, as if sleep, and a very sharp image of the Brooklyn bridge and the lower Manhattan materializes over crumpled sheets. To create this surrealistic picture, Morella installed his camera into a room that served as a scuba chamber, and left the shutter open for five hours. The impaired vision was fixed on the film. In addition, he used a prism to turn the image.

Color, shape, perspective - all stirred in a multicolored puzzle, created by Morella in the living room of one Venetian house. "I want people to lose in guesses, what came from," says the Master, sprobed the view of the Grand Channel on the wall, where the jungle was already drawn. The hypnotic chaos believes the shadow from the chandelier.
