There is a relationship between the shutter and the aperture, and also with the sensitivity of the camera sensor.This relationship is called the exposure triangle, and in a future episode, I will explain the exposure triangle in less than 10 minutes.All cameras are generally the same.This principle applies to any kind of camera. Think about an iPhone as the camera body, with a camera lens attached to the body, and an aperture which on my iPhone XS is fixed at F1.8.How was this for you?So this is the level of explanation that works for me, which I hope works for you too? We have learned very quickly what a camera is and how it works. Now are there things in here which need much more detailed explanation? Yes, of course.I’m trying to build myself up here from small beginnings and straightforward explanations by taking (not attacking) things at this level. Like I said I am going to explain the exposure triangle. I’m also going to talk about some of the general camera settings – obviously, there are some that are specific to each individual camera and some that are universal principles of the topic.A universal ruleWhatever the camera the exposure triangle applies – aperture, shutter and ISO.Strange termsThere is some very strange and confusing terminology in photography which I will try to get to the bottom of.

This relationship is called the exposure triangle, and in a future episode, I will explain the exposure triangle in less than 10 minutes.

This is not what I said in the podcast, but is a much better answer.You can listen to the episode hereOr keep on reading. Or do both. Entirely up to you!What is a camera then?Well, the word camera comes from Camera Obscura. Obscura is a Latin word that means darkened in English. Camera is also Latin, meaning vault or vaulted room. It also has Greek origins as well.So camera obscura came into being and that means dark chamber. So there you have it – next time you look at your camera, think of it as a dark chamber!It all makes sense, doesn’t it? A dark chamber can become a lightproof box.How does light get into the box?The lightproof box has an opening in it which is called the shutter. When the shutter opens light gets into the lightproof box where the camera sensor is.So that’s the fundamental of thisOkay, let’s have a look at the fundamental components of a camera.I’m talking about a conventional camera with a camera lens on a camera body.Camera bodyThe camera body is the bit that has all the electronics and clever stuff in it. It also has such things on the camera body, controls and dials with which we can change all those many, many settings.Camera lensThe lens to attaches the camera body by a mount. The lens is the thing that controls the light and the sharpness of the light getting in (not what my transcript says so time to correct this!Camera sensorThe camera body is where the very important sensor is. Now what’s a sensor? If you think of a film camera (if you’re old enough) there was a place where you put the film, in the back of the camera body. You had to wind the film onto the first bit to take a photo with It.Well on a modern camera, the sensor is where the film was in simple terms.Camera shutterThe shutter is the thing that lets light reach the sensor. Press the shutter release button and the shutter opens, exposing the camera sensor (or film) to the light coming in through the lens.Again, I don’t want to get too technical here!So a camera is a light-proof box with a shutter in it.So how does the light get onto the sensor?Well, the next thing is what’s called the camera lens which is either attached to or built into the camera body. On conventional DSLR and mirrorless cameras, you can change the lenses. There is a very unhelpful acronym ILC which means interchangeable lens camera. To be perfectly honest with you I don’t see the point of that.The camera lens has all the optics in it to focus what the camera is pointing at onto the sensor (or film).The other thing that the camera lens contains, as well as the optics, is the aperture.In most cameras the aperture is adjustable, meaning you can change the size of the opening in the lens which reduces or increases the amount of light getting through to the camera sensor.Shutter and aperture – the special relationshipThere is a relationship between the shutter and the aperture, and also with the sensitivity of the camera sensor.This relationship is called the exposure triangle, and in a future episode, I will explain the exposure triangle in less than 10 minutes.All cameras are generally the same.This principle applies to any kind of camera.

Diffraction is when light waves bend around obstacles placed in their path and bend into the shadow region. This phenomenon is responsible for interference patterns being formed on screen placed behind diffraction apparatus for example. Equations are valid for calculating conditions and positions of interference bands.

So camera obscura came into being and that means dark chamber. So there you have it – next time you look at your camera, think of it as a dark chamber!It all makes sense, doesn’t it? A dark chamber can become a lightproof box.How does light get into the box?The lightproof box has an opening in it which is called the shutter. When the shutter opens light gets into the lightproof box where the camera sensor is.So that’s the fundamental of thisOkay, let’s have a look at the fundamental components of a camera.I’m talking about a conventional camera with a camera lens on a camera body.Camera bodyThe camera body is the bit that has all the electronics and clever stuff in it. It also has such things on the camera body, controls and dials with which we can change all those many, many settings.Camera lensThe lens to attaches the camera body by a mount. The lens is the thing that controls the light and the sharpness of the light getting in (not what my transcript says so time to correct this!Camera sensorThe camera body is where the very important sensor is. Now what’s a sensor? If you think of a film camera (if you’re old enough) there was a place where you put the film, in the back of the camera body. You had to wind the film onto the first bit to take a photo with It.Well on a modern camera, the sensor is where the film was in simple terms.Camera shutterThe shutter is the thing that lets light reach the sensor. Press the shutter release button and the shutter opens, exposing the camera sensor (or film) to the light coming in through the lens.Again, I don’t want to get too technical here!So a camera is a light-proof box with a shutter in it.So how does the light get onto the sensor?Well, the next thing is what’s called the camera lens which is either attached to or built into the camera body. On conventional DSLR and mirrorless cameras, you can change the lenses. There is a very unhelpful acronym ILC which means interchangeable lens camera. To be perfectly honest with you I don’t see the point of that.The camera lens has all the optics in it to focus what the camera is pointing at onto the sensor (or film).The other thing that the camera lens contains, as well as the optics, is the aperture.In most cameras the aperture is adjustable, meaning you can change the size of the opening in the lens which reduces or increases the amount of light getting through to the camera sensor.Shutter and aperture – the special relationshipThere is a relationship between the shutter and the aperture, and also with the sensitivity of the camera sensor.This relationship is called the exposure triangle, and in a future episode, I will explain the exposure triangle in less than 10 minutes.All cameras are generally the same.This principle applies to any kind of camera. Think about an iPhone as the camera body, with a camera lens attached to the body, and an aperture which on my iPhone XS is fixed at F1.8.How was this for you?So this is the level of explanation that works for me, which I hope works for you too? We have learned very quickly what a camera is and how it works. Now are there things in here which need much more detailed explanation? Yes, of course.I’m trying to build myself up here from small beginnings and straightforward explanations by taking (not attacking) things at this level. Like I said I am going to explain the exposure triangle. I’m also going to talk about some of the general camera settings – obviously, there are some that are specific to each individual camera and some that are universal principles of the topic.A universal ruleWhatever the camera the exposure triangle applies – aperture, shutter and ISO.Strange termsThere is some very strange and confusing terminology in photography which I will try to get to the bottom of. I think it’s fair to say that if photography was being invented today we wouldn’t have all these things that we have now like the size of the sensor, the terminology and complications of things like the exposure triangle.I’m rambling nowHow long should a podcast episode be? The answer is as long as it needs to be – I won’t stop if I get to 10 minutes and have not finished.So what’s next on the Photography Explained Podcast?PE3 – How To Take A Photo? (Not in the podcast episode as I did not know).Thanks very much for listening, I hope you enjoyed this episode. If you did, please leave a review and rating wherever you get your podcasts from.

Well, the word camera comes from Camera Obscura. Obscura is a Latin word that means darkened in English. Camera is also Latin, meaning vault or vaulted room. It also has Greek origins as well.

So this is the level of explanation that works for me, which I hope works for you too? We have learned very quickly what a camera is and how it works. Now are there things in here which need much more detailed explanation? Yes, of course.

Well, the next thing is what’s called the camera lens which is either attached to or built into the camera body. On conventional DSLR and mirrorless cameras, you can change the lenses. There is a very unhelpful acronym ILC which means interchangeable lens camera.

The camera body is the bit that has all the electronics and clever stuff in it. It also has such things on the camera body, controls and dials with which we can change all those many, many settings.

Hi everybody, welcome to Episode Two of the Photography Explained Podcast. In this episode, I will explain this – how does a camera work?

Refraction is when light rays enter a different medium of different optical density and change direction or bend. In this case, Snell's Law is valid to calculate the degree of refraction. If it enters a more optical dense medium it is refracted towards the normal.

There is some very strange and confusing terminology in photography which I will try to get to the bottom of.

A camera works by exposing the camera sensor to light when the shutter opens. The amount of time the shutter is open, the size of the opening in the camera lens and the sensitivity of the camera sensor to light are all adjustable and set by either the camera or the photographer to create the exposure.This is not what I said in the podcast, but is a much better answer.You can listen to the episode hereOr keep on reading. Or do both. Entirely up to you!What is a camera then?Well, the word camera comes from Camera Obscura. Obscura is a Latin word that means darkened in English. Camera is also Latin, meaning vault or vaulted room. It also has Greek origins as well.So camera obscura came into being and that means dark chamber. So there you have it – next time you look at your camera, think of it as a dark chamber!It all makes sense, doesn’t it? A dark chamber can become a lightproof box.How does light get into the box?The lightproof box has an opening in it which is called the shutter. When the shutter opens light gets into the lightproof box where the camera sensor is.So that’s the fundamental of thisOkay, let’s have a look at the fundamental components of a camera.I’m talking about a conventional camera with a camera lens on a camera body.Camera bodyThe camera body is the bit that has all the electronics and clever stuff in it. It also has such things on the camera body, controls and dials with which we can change all those many, many settings.Camera lensThe lens to attaches the camera body by a mount. The lens is the thing that controls the light and the sharpness of the light getting in (not what my transcript says so time to correct this!Camera sensorThe camera body is where the very important sensor is. Now what’s a sensor? If you think of a film camera (if you’re old enough) there was a place where you put the film, in the back of the camera body. You had to wind the film onto the first bit to take a photo with It.Well on a modern camera, the sensor is where the film was in simple terms.Camera shutterThe shutter is the thing that lets light reach the sensor. Press the shutter release button and the shutter opens, exposing the camera sensor (or film) to the light coming in through the lens.Again, I don’t want to get too technical here!So a camera is a light-proof box with a shutter in it.So how does the light get onto the sensor?Well, the next thing is what’s called the camera lens which is either attached to or built into the camera body. On conventional DSLR and mirrorless cameras, you can change the lenses. There is a very unhelpful acronym ILC which means interchangeable lens camera. To be perfectly honest with you I don’t see the point of that.The camera lens has all the optics in it to focus what the camera is pointing at onto the sensor (or film).The other thing that the camera lens contains, as well as the optics, is the aperture.In most cameras the aperture is adjustable, meaning you can change the size of the opening in the lens which reduces or increases the amount of light getting through to the camera sensor.Shutter and aperture – the special relationshipThere is a relationship between the shutter and the aperture, and also with the sensitivity of the camera sensor.This relationship is called the exposure triangle, and in a future episode, I will explain the exposure triangle in less than 10 minutes.All cameras are generally the same.This principle applies to any kind of camera.

The lightproof box has an opening in it which is called the shutter. When the shutter opens light gets into the lightproof box where the camera sensor is.

Howcamera Works

The image sensor is the film to a film camera, or the retina to the human eye. Its performance determines the picture quality or sensing precision.

A camera is a lightproof box with an opening in it which allows light to pass through to the sensor where the image is recorded. The camera body is the box, the lens is the opening and the shutter is the thing that opens to let the light in. The lens focuses the image on the sensor giving a high-quality recording of the scene the camera is pointing at.

The shutter is the thing that lets light reach the sensor. Press the shutter release button and the shutter opens, exposing the camera sensor (or film) to the light coming in through the lens.Again, I don’t want to get too technical here!So a camera is a light-proof box with a shutter in it.So how does the light get onto the sensor?Well, the next thing is what’s called the camera lens which is either attached to or built into the camera body.
