For you who are a camera and photography lovers, exposure may be one of the things you’ve ever heard. The term refers to a feature that can be utilized to maximize the results of photography. Unfortunately, the general public and those who have long in the world of photography is not much use. It is mostly due to lack of information about this important feature.
The general public still uses auto mode when they do portraits using their cameras. In addition to being the easiest and fastest, using the auto method is also more practical. Many people are transfixed by this mode because of these advantages.
But for those of you who want to develop creativity, you need to use the exposure mode. With this mode, you can develop the creativity of photography and play with lenses that produce more necessary shots.
For those of you who are beginners, you can see information on the basics of the technique of using the mode. However, deepening the basics of exposure is very important because with that you can later develop it to a higher level.
Exposure by photographers
Reviews on exposure modes are not something that photographers do not pay attention to it. One famous photographer named Bryan Peterson has reviewed it in his book.
The book under the title Understanding Exposure it became one of the points of photography to learn about the unique method. In this book, Bryan describes many things about photography. The one is an easy explanation of the concept of exposure.
By knowing the concept, a photographer will be able to improve the quality of photography in stages. He is also motivated to hone his skills in different ways. Therefore, knowing the concept of a thing is one of the basic needs, as well as the concept of exposure.
The concept of exposure
In Bryan’s above book, he mentions that there are three main elements of the exposure . This book will help us to Understanding the Concept of Camera Exposure. All three are ISO, Aperture and Shutter Speed. The discussion of the three will be described below. You need to understand each of them in basic ways before practicing the exposure use.
The first element is ISO. ISO is a measure of the camera’s sensitivity to light. The higher the ISO scale that you use, the higher the sensitive sensor capability of the camera to the ambient light conditions. ISO is not only found in digital cameras and DSLRs but also on mobile cameras. So when you scale up the ISO, the image you want to produce will be brighter than the lower ISO scales.
The next element mentioned by Bryan is Aperture. Aperture is the definition of the lens width size when you shoot the image. In the case of photography, this is also called an opening. Aperture is usually indicated by f / number. An example is f / 22.
What is the meaning of that number? The maximum is the size of the diaphragm. In camera phones, camera aperture is usually only up to f / 1.8. In digital cameras, it is usually found up to f / 1.4 even larger. You need to know that the smaller the numbers are listed, the larger the lens is open thus; the shoot that you get will be wider.
The last one is an element called Shutter Speed. This Element is the definition of open shutter rules when the user shoots. The open shutter will allow the light to enter into flax to the camera.
Normally, the shutter speed is measured by seconds or materials in a much smaller fraction than the second. An example size of shutter speed is 1/10 or even 1/500. Keep in mind that the bigger it captures it, the sooner the shutter opens to receive the light.
However, you should not open the shutter for too long. If the shutter is too long opened then the light that enters the lot and causes the picture looks pale. This is called Overexposed. You need to re-capture if this happens.
Also, you should also note that the shutter speed has several modes and the size of seconds longer. It usually applies to indoor photos that are lack of light or dark. Thus, the concept of shutter speed should pay attention to the state of light around.
The interaction of these three elements is what is called exposure. Just changing one element will usually change other elements.
Bryan mentioned that the interaction between the three is illustrated as the Photography Triangle. He also mentioned that each of the above elements would interact with the camera as well as the light.
Understanding the Photography Triangle
To facilitate the understanding of photographic triangles or commonly known as exposure triangles, then there is a parable used as an explanation.
The parable is exposure is a water tap. With the concept of tap water, then the shutter speed is the time that defines how long the tap is open. Then the aperture is how wide the tap opened. Then, ISO is a water pressure driven by the company. For the water coming out, it is like the light received by the camera sensor.
With an easier understanding like this, you might be able to describe what kind of exposure. You need to notice that the parable above is not a perfect parable. But with the basic knowledge of the above parable, there is a simple picture of exposure.
From the above parable, you can imagine it and prove that all three have a very strong relationship. If exposure is the amount of water coming out of the tap, then that means that you can modify all three settings.
An example is to change the shutter speed as a tap. By changing this, then you have automatically changed the aperture because the size of the open tap will change. So, it is also with the water pressure that can be changed.
With all the mutually changing relationships with each other, now you can set your camera for better quality shots. Even in the dark, you can use the exposure to maximize the image.
