How To Make A Pinhole Camera
This video is a step-by-step instructional project guide, explaining how to make a pinhole camera using simple everyday home items. It's a great project to do with your kids, and simple enough for them to understand and learn.
Today, we're going to make a pinhole camera out of everyday items at home. This is something you can do with your children, very simple, and it teaches them a little bit about light and the fact that light only travels in straight lines. We'll see that later.
All you need to make a pinhole camera is a box, a box like this, and you're going to cut some holes in it. A cardboard box, pair of scissors for cutting, you need a skewer or something like this to make a hole, some tin foil to make the pinhole with, and you need some tracing paper. And if you can find any or know where to find any, get some lens or magnifying glasses because that will help to make the image crisper in the pinhole camera.
What you're going to do is make a pinhole in your tin foil, like this, and with the pinhole camera, it's a trade-off really between having a small hole and having a very crisp high definition picture than having a bigger hole and it letting more light in, so you get a brighter picture. So I'll make a biggish hole. I'm going to put some tape there, use the tin foil so you get a nice round hole.
If you did it in cardboard, it wouldn't be so round. I taped around the tinfoil so that no light can get in any other way other than in the hole. On the back of the box, you're going to put some kind of paper, some kind of see-through paper.
It could be tracing paper, tissue paper, but it needs to be see-through. So you just need to put it on the back of the box like that. It's as simple as that, that's your pinhole camera and now, I'm going to show you how it works.
So I'm holding the pinhole camera up here to a window or bright object, you could use a light bulb or window like this. You will start to see an image of the windows on the tracing paper in the back, so you really need a dark room to do this. But if you put a lens in front of it, you can see the picture gets much more focused, you can see the edges of the windows.
What you'll notice, and you might not see it, but you'll see it when you try it, is that the image is upside down, and that's how a camera works. So that's a pinhole camera. So, here's a real pinhole camera, an older pinhole camera.
This was some of the earliest cameras that were used and all they are, are quite simple, it's a hole in the front and a place to hold photographic film or plate at the back and when you press the shutter, it just opens the shutter, lets the light in through the pinhole and exposes the film. That's a pinhole camera. If you want to make a real pinhole camera and take a photograph with it, you would have to make it out of different materials.
It would have to be blackened materials so light can't get it, would have to be sturdier than a plastic box or a cardboard box like this. You would have to have the film that you can attach to the back and would have to improvise a shutter at the front that you can open and close when you wanted to expose the film. Otherwise, it works exactly the same way.
So that's how you make a pinhole camera. .
