A camera is essentially just a box.On the front end of the box there is a hole you might recognize it more having a piece of glass in it. Maybe it would be different shape, but we’re just going to make it into a very simple box and we’re going to view it just from the side. Now light enters this box through that hole and in modern cameras it is always with some sort of with some sort of piece of glass and we’ll talk about lenses a little bit later, but that light is focused through that hole in the wall inside there’s. No other holes anywhere else in the camera just in the front and that light is focused through that hole and then cast onto the back wall of the camera.
This is basically, if you remember the history lesson, it’s just like a camera obscura, it’s the very same principle, so we’re going to step back a step here, I’m going to delete a few pieces of our camera and we’re going to add in something that was very Important in the development of the camera – and that is the lens, so here’s our body – they made the hole a little bit bigger so that they could mount a lens on it and we’re going to make our lens. Let’S make our lens green and we’ll make our lens sort of like this right here and we’ll put it kind of a long lens like this all right. So here’s our lens and we going to see it kind of comes in here a little bit right. There. All right now inside of that lens, so I just made the outside bit of the lens inside of the lens.
It’S some glass, so there’s usually lots of pieces of glass. So we’ll say: here’s one piece of the glass and maybe there’s another right here and maybe there’s some space – have a piece of glass right here. Maybe there’s another piece right here right here and at the very end, there’s another piece of glass right here now. What happens is that same the same way that light came in before light is cast over onto the lens it travels through, and it comes out. The other side and lands on the back of the camera and just like before red comes in bounces around in here, takes a little trip and is then in the end cast in this direction like that, so you get an idea of how all that works.
So I’m going to go back a few steps here and delete that so you’ve got your light coming in I’m going to I’m going to reintroduce our light streaks here, because I think they’re kind of cool – and this is basically the same principle. This is still a camera obscura because we don’t have any film. Yet this is it’s a camera without film, which is a camera obscura and you could in theory, if you were small enough, you could jump inside the camera and you could draw what you were seeing on the back wall of the camera. Now, at some point like you might have seen in the history course or in the history lesson, some people figured out that there were leant light-sensitive chemicals and so at some point someone came up with the idea of making film, so film was produced and we’re going To make our film brown and it was put on the back of in the back of the room or in the back of the box in the back of the camera. So here’s our film – and this is basically early on it – would have been glass or some piece of metal covered and coated in some sort of light-sensitive silver nitrate of some kind, and eventually it became a piece of plastic or sort of something along those lines.
And then that would be covered in the silver nitrate and in a dried form. Early on these actually were glistening wet. They would stick them in take the photograph while the plate was still wet and then they’d take it out and go develop it. So this is a sort of a situation where you’d out now need to find a way to keep the film from being exposed, while the camera is exposed to light, because, right now, if we were just to have your film sitting in there, it would always be Exposed to light so you need to make a shutter early, shutters were actually often inside of the lent, and there was just like a little door that you would pop open. The light would come in and it would hit the film and expose it.
And then you would pop it back down and a light would stop, and that was that was your shutter. But as film got faster, the shutter needed to become more more quick and there are still cameras that use a lens like a lens shutter type. But in general, most shutters on most cameras we’re going to make the shutter on this camera red are right in front of the film, so the film is sort of in a kind of a case of some kind, something like that and then in the front. There’S basically a big door and sometimes it’s a series of tiny little doors that all open at the same time. Something like this and they’re all kind of connected, and so when the picture is being taken.
All of these sort of like the blinds in a in a window or something they all pop, they all pop forward or pop down whatever. However, this that the the shutter works and they slide and I slide down and then they pop back up into place. So it’s kind of like almost like those those kind of blinds that you have on your windows, that you can open and close by twisting the twisting the handle it’s sort of a similar, similar situation but at the same time as they’re sort of changing they’re. They’Re. Horizontal tilt, they’re also sliding up and down, and that basically creates the second like a very small moment where a light is then cast on the film.
So your film is is protected from being exposed and then it’s exposed to the light, and then it’s closed to again, so this prep represents then the basics of photography. This is really. These are the most essential elements to a camera. There’S also the thing there’s also the problem that you can’t necessarily control the amount of light coming in with this lens. So you just have a set amount of light that you always have to work with that brought about the idea of the aperture.
The aperture is kind of a little bit more of a confusing concept and we’ll talk about more in another lesson. But basically what aperture is is it’s kind of like shutters for your for your lens and often that piece of machinery is either here and the lens. So like right, where my arrow is or kind of more forward and we’ll make ours up here, because we just have space for it, I didn’t leave space back here from the side. It would look something like this from the side. It would look like we’ll.
Just look like a little hole, and basically this is a piece you would twist and twist like sort of a wheel on the updates on the outside of your lens, and it will close and open this window. So from the front, if you were to look at the front of this piece right here, you have your lens and then you have what are called blades and they’re all sort of going like this and there’s a little hole in the middle and as you turn This this this right here, this sort of grip. As you turn it, this hole gets bigger and smaller. So you can control this. The amount of light that’s coming in sort of like opening and closing the shades on a pea on a window, and this has the effect of allowing more or less light in which has lots of lots of purposes and lots of lots or lots of uses.
Sorry and we’ll explain those later on when we start talking about aperture more in depth, but just so you know that is how aperture works. So I’m going to delete our little diagram here. So we’ve got aperture now comes the problem of the viewfinder. Now we’re not exactly sure how we’re going to see all of this now we’re going to make this camera into what’s called an SLR. Now, there’s lots of different types of viewfinders one.
The early viewfinder was just basically two squares, so you de speak two little squares on the top of the camera, and you would then, with your eye you would you would make these little boxes so that when you look through it over top of the camera, you Would see about what your lens would see, but you know this is a pretty primitive way of doing my first ever camera had one of these, and it was just a little two dollar camera that my mom bought me for my birthday, when I was really small And it does work, it works really well, but it’s not the most advanced way to see it so eventually, over time there have been lots of different ways of from creating a viewfinder. This is something a little bit like what you would call like a rangefinder something along those lines, but what would eventually kind of come to be the standard in photography or what is sort of considered the best solution to this problem. Right now are one of the best solutions to this is: what’s called the single lens reflex, so we’re going to add now a mirror to the whole situation, so we’ll take a mirror, and so the light would normally be coming in and hitting this and just not Going anywhere, but what scientists and camera makers decided to do was try putting a mirror right here, so I put in a mirror – and this reflects the light up. So your light comes in right. Here hits the mirror and goes going right up to the top of the camera.
So up here they made a very complex we’re going to add some more hardware to our camera. Here made a very complex little set of mirrors and prisms, so the light goes up and it lands inside of a big prism that is sitting up in the top of the camera and I’m not exactly sure how the light bounces around there’s some good diagrams of It online, but you take your eye here. We’Ve got our eye again and it’s looking into this there’s a hole right here and it’s a little window that looks right in to this and basically the light is going boying hitting the mirror going up up into here. Bouncing around a little bit now this is not accurate. Obviously I didn’t do a very good job on this and then it’s coming back out right here, so the light you’re seeing it go all the way up.
Ding go this way. Go that way. There must be something like kind of like that in there somewhere and the light comes back, and you can see exactly exactly what this lens is seeing. What you’re, seeing through this lens now, when you want to take the picture, you push the button and this piece of mirror. Well, I didn’t make it.
I made it a little too big, so it may wouldn’t look like it would work, but it actually would youwould. This mirror would flop up to an up position, so the mirror when it was when you’re taking a picture is right here. So there’s like a spring on it that kind of has a hinge and it sort of just goes think pops up, and you can imagine it not being here anymore and then that light passes through that there pass and then the shutter opens. While this is happening. So you’ve you pushing the button, has done two things: it’s open the shutter and it’s popped the mirror up and then the light travels in through the lens.
The two digit hits the film exposes it and then, when the camera says that the exposure is correct, then everything closes back down. So the mirror drops back down the shutter closes and the film is exposed. The only thing that they’ve really done in recent times. It changes any of this is that they’ve taken this piece of film and they’ve developed digital sensors. That can basically do the same thing and actually can now we’re learning.
Do a lot more, even and they’ve replaced that so we’ve got a digital sensor and they’ve added some sort of memory space. So we’ll just imagine that this is like a little little card down here. This is what you save your your files on. So the light comes in hits the digital sensor and the digital sensor is just like a little series of electrical nodes that sense the light and then they pop out bunches of ones and zeros, and they go through put a little computer in here. So there’s a little computer here right there and the information goes ding-ding-ding into the computer computer processes.
It saves it as a file and drops it into your card, and your picture is now here on your card and then you take that out, put in your computer and use it, but sometimes you won’t maybe have a mirror here. You’Ll have there’s lots of different ways of doing this little part here, but this is basically how it works. They’Ve added also in recent years screen so on the back. You’Ve got even with the early digital cameras. You have a screen just a TV version of this.
There might be, there might be some sort of either the shutter is some different kind of shutter, and the sensor is always exposed to the light and so you’re, seeing directly what the sensor sees, or they have some sort of system does the same purpose of taking This light that you’re seeing and then instead of displaying it up top, they just display it on a screen.
