Before understanding aperture and depth of field in simple ways, you need to know first what the aperture is. Well, an aperture is how big of the lens’ size which is open when you take a photo. When you push the shutter button, the hole in front of the camera sensor will open and the aperture setting which determines how big the hole opened. When the hole opens bigger, the certain amounts of light will be allowed to reach the camera’s sensor.
Then, about the functions of the aperture, it has two purposes. The first one is to control the amount of light which is passing through the lens. It means that you will have to change the way of your photo look. The second function is to control the depth of field. What does the depth of field mean? Yea, it is how much of your image is in focus on the subject.
For the additional information for you, a small depth of field will make the most important subject sharp, so everything which is in the background will be shadowy. On the other hand, a large depth of field will keep all of the image sharp. Moreover, this depth of field concept will be more useful, especially in portrait and macro photography. However, all of the specialization will need it.
Understanding More About the Aperture
Talking about the aperture and depth of field, you should know that there are some aspects to help you understand more about aperture.
- How the aperture works
Firstly, if you want to have more understanding about aperture, it is good for you to know how it works first. Thus, it will be simpler for you to understand it. Well, the way it works is when the wider the lens opened, so the more the light gets into it. The result of it can increase the brightness of your photos. Therefore, if you need to get bright photos when there is not sufficient light, you can make the aperture stay wider.
Then, you need to know that the lens aperture can also influence the sharpness of the picture. You should pay attention to it when you need to get a reliable picture of the sharpness. Hence, you should be careful in managing it.
- Understanding the aperture value
Secondly, you need to know that the aperture value is written in units of “f/.” There are many beginners not right in using the aperture because they get lack of understanding in reading the aperture value. It can be so because you should understand the aperture value in reverse. For example for the wide aperture, the small value represents it. The nearest aperture is represented by the big value. Thus, this condition sometimes makes the beginner get wrong in setting the aperture.
- Understanding the F-Stop formula
Simply explaining, f-stop is a value level of the aperture. Then, f-stop is also known as f-number. This formula is often used in counting the exposure value, include the elements that make an exposure, like shutter speed, aperture, ISO. From all of those elements, the computation of ISO is the easiest one. It can be so because the ISO value level is the result of the multiplication of two from the previous value. They are ISO 100, 200, 400, 800, and so on.
- How to use aperture
To know the way to use the aperture is also important for you if you need to get a good understanding of the aperture. Well, like a shutter speed, you can also set the aperture as you want. You can make it happen by choosing a manual exposure mode (M) or aperture priority. That choice will let you manage the aperture as you like. However, you can do it with the auto mode or program (P). So, make sure to change it first to manual mode before setting.
Also, if you use a Canon, the shutter priority is written in a symbol (Av). While for Nikon and any other cameras, the shutter priority is written in a symbol (A). So, go to it first can be the beginning step in setting the aperture as you want.
After you finish changing to the manual mode, you can choose the aperture menu on the LCD monitor. Then, you can change the value as you need. It is simple, isn’t it? Thus, when you succeed in doing it, it means that you have understood the main basis of using cameras.
Furthermore, after you know all of the explanation of aperture above, it is also necessary for you to know further about a depth of field. Yes, depth of field is used to describe the primary difference between two images. With the role of depth of field, you can make one image of two look in-focus more than the other. So, it can be used to make the result of the picture more interesting.
Then, with aperture, you can manipulate the depth of field in the photograph just by adjusting it appropriately. The key of the aperture you should know is, ‘the wider aperture creates a shallower depth of field. The narrow aperture creates greater of a field. You should remember it so that you will not experience a misunderstanding in operating it.
Talking about aperture, you must know that it will also be interesting to talk about photography. To get good picture or photos, the photographer should pay attention to the aperture and depth of field to get best and exciting result. Thus, by understanding well about those two aspects, aperture and depth of fields, will help you to be a professional photographer who can catch a strongly attractive picture in every shot.
Additionally, when you have known aperture and depth of field well, to find the unbalanced light to take a picture will not be a big problem. It can be so because you can use the role of an aperture to adjust the brightness of the light to be balanced and as you want. Yes, that is all about the aperture and depth of field which can hopefully be useful for you.
