Knowing about the exposure triangle in the realm of photography is quite important. This is because the photography triangle is very important. On top of that, exposure triangle photography is also an extremely important topic that should not be ignored. Thus, you must know about the exposure triangle.
Along with it, the basics of the camera, its speed, and overall how the triangle should be are the main topics. Thus, by all means, you must learn about the exposure triangle. What is an exposure triangle, and what other components stay in it? You must know all to excel in photography.
All About Exposure Triangle: What is Photography?
Photography is defined to be known all about capturing light. In fact, the etymology of the word “photograph” is basically “light drawing.” To make a photograph that one can definitely see, we have to control both the amount of light that is exposed to a photosensitive surface. This can be any form of film or a digital sensor.
It can also control the sensitivity of that surface to the light. Thus, to know all about the exposure triangle, you will have to first know a bit about the physics and characteristics of light. After this, you will have to know how a camera and lens combine to control exposure by using what is commonly known as the “Exposure Triangle.” This will be explained in the blog as you read on.
What Is Exposure Triangle?
The Exposure Triangle is known to genuinely comprise of a aperture, shutter speed, and ISO. These three camera and lens controls work or operate together to regulate the amount of light that makes it to the light-sensitive surface. This is relating to the aperture and shutter speed and the sensitivity of that surface such as film or digital ISO.
Not only do those three controls affect the light of a photograph, but they also have unique “side effects.” The aperture is known to control the depth of field shutter speed. It can blur or freeze action, and the ISO can add or subtract film grain or digital noise from an image.
Exposure Triangle: The Three Values
Below is all the knowledge you need to know about the exposure triangle. This will be extremely helpful to you with regard to knowing about the exposure triangle and, thus, knowing all about the three values that are in it.
Aperture – Exposure Triangle
Like the iris of your eye, the aperture blades on the lens of a camera control the amount of light to be let into the camera lens. This is because the amount of light that reaches your camera’s image sensor will determine what the exposure looks like.
Each aperture setting on the lens is referred to as an f-stop. This is a fraction that indicates the diameter of the lens opening. The aperture in the exposure traingle also determines the depth of field and sharpness. Every lens has a “sweet spot” or “critical focus”. This is usually between f/4 and f/11.
Shutter Speed – Exposure Triangle
While the aperture determines how wide the lens opening is, the shutter speed of the exposure triangle determines how long the lens stays open. How will it let the specific amount of volume of light into the sensor be determined by the aperture? A faster shutter speed, like 1/1000th of a second, has the effect of freezing motion. On the other hand, a slower shutter speed, like 1/60th, will blur motion in a scene.
ISO – Exposure Triangle
ISO is defined to be the international standard of measurement that determines how sensitive a photographic film emulsion or digital sensor is to light. When increasing the ISO allows you to work with less light. However, if the ISO is increased, oftentimes, there will be more noise and less detail within your video.
In other words, increasing your ISO will bring light into dark images but can diminish the quality of the shot. At lower ISOs, the degree of your camera’s signal is significantly large compared to the noise; this means that the noise generally remains inconspicuous.
Exposure Triangle: What To Do When Shooting?
When shooting on your device, it is best to keep your ISO low to avoid noise; however, your determined ISO level ultimately depends on the surrounding environment and lighting conditions.
For example, if you shoot in a low-light setting, you will need a higher ISO to expose the photo and brighten the film properly. On the other hand, when one is in a very bright setting and trying to capture footage, a lower ISO would be appropriate to avoid noise getting into your photo or video.
How to Choose Camera Settings in Exposure Triangle?
When it comes to choosing camera settings utilising the exposure triangle, it helps to decide which setting will dictate the photographer’s decision. Will it be aperture shutter speed or ISO? Now, how does one answer that question?
Thus, if you’re in a tricky lighting situation, you will have to go forward in using your best camera settings. This is to be done for a tricky lighting situation. Therefore, if you are getting creative with motion blur, sun stars, or something else, then you will have to use your camera setting based on that.
Best Shutter Speed – Exposure Triangle
The best shutter speed is known to be the one that lets in enough light. All of this is done while not causing any unintentional motion blur or camera shake. However, unless you want a long exposure to capture motion which includes photographing a waterfall, then you will probably want to shoot at 1/200 or greater. Or you will want to shoot 1/the focal length you’re shooting at the exposure triangle.
Best Aperture – Exposure Triangle
The best aperture in exposure triangle is when the lowest one your camera allows is the one which lets in maximum light allowing you to shoot at higher shutter speeds and lower ISOs. That is, by all means, done unless you don’t want the shallow depth of field or bokeh effect. This is because you might want a higher aperture for a wider depth of field. This can range from taking a group picture and wanting everyone to be sharp.
Best ISO – Exposure Triangle
The best ISO is defined to be the lowest ISO that you can use in the exposure triangle. This is given as per the restrictions of your conditions. Outside on a well-lit day, you might shoot at ISO 100 all day. However, indoors, you might need to raise your ISO. This is required to balance your exposure or risk of having a too-slow shutter speed.

What Do People Say About Having A Good Camera?
The stated statements are told by people who believe in having a good camera. Thus, get ahead to know it thoroughly and properly:
#1 @jeanbergen
That’s the million-dollar question! One I am asking myself right now. A good camera makes a difference in the quality of the image. However, the photographer’s creative eye and the composition’s artistry are equally, if not more, important than the tool.
#2 @2electric.boogaloo2
That’s an interesting question. I don’t think it improves photography, but it may improve the quality of a photo. But that’s only because you’re buying the technology.
Example: If I buy a real camera instead of using my phone, the photos will likely be the same (even though I’m trying to improve my skills every day), but the quality of the photos will be much better.
#3 @hrbutler06
I don’t believe so. You can get incredible photos with inexpensive gear and a good eye! All the money in the world can’t buy you a natural ability to see things others don’t.
#4 @tam.erdt
In my opinion, it depends on your requirements. If, for example, you need to print your photos in large sizes, you will need a camera with a full-frame sensor, and if you need to do sports or animal shots, you will need quick autofocus, etc.
But for my kind of landscape photography, it’s not essential to have expensive gear. The truth is, though, life would be much easier because a bigger sensor and higher dynamic range would allow me to take fewer landscape shots, and I would not need to do bracketing in most cases.
Conclusion
Thus, this is all you should know about the exposure triangle. The exposure triangle is quite important in terms of photography. Thus, get ahead with it and know more about it thoroughly. This will help you level up the exposure triangle in your photos.
