What is aperture settings? by Hasif Ahmed

You’re a photographer? or you want to be one photographer? Whoever you are, the concept of aperture settings must be clear in order to take good photos. Either you’re a beginner or you’re interested to know about it or even you’re doing your school homework, this my short article shall help you with it. Let’s begin the fun and explain you in my own words.

Q. What is Aperture?

A. Aperture is a type of breach or diameter that passes the light in your camera through lens. You didn’t got anything or did you? Okay again, aperture is like your eyes, when you open your eyes then you start consuming light through pupil (the black circle in the middle). This pupil here act like the camera’s aperture. So, when you click shot button, then the shutter opens and the total diameter of the opening passage is the measurement of your aperture settings. That opening hole size determines the amount of light the camera will absorb.

Q. How Aperture is measured?

A. It is usually measured in F-stop for example f/22 or f/2.8 in a manual aperture control settings in a DSLR camera. In compact digital cameras, this things are automatically adjusted for which those cameras are never considered as PRO (otherwise photographers wouldn’t have been earning big sum of money with their SLrs).

The measurement kinda works in the opposite way as we generally might think because these settings are expressed in decimal numbers. Remember the following key function of F-stop:

Higher numbers of F-stop or aperture settings => Allows lowest amount of lights
Lower numbers of F-stop or aperture settings => Allows highest amount of lights

We’ll review a picture that were taken in aperture priority settings for better understanding that what we  can do with aperture and how it is useful to us.

Photos taken in different aperture settings by Hasif Ahmed

The picture above shows brief details about the pictures taken in different aperture settings or you can say f-stop numbers. This example is to make you understand that how aperture settings effect in the camera.

Since you already now know that when at what settings the camera lets more or less lights into the camera so you should be able to judge by the numbers of what is happening. (Sorry about the website address watermark on the pictures, I had to do it to protect the images from being stolen by someone else).

First from the left, which has f/2.8, where more light has entered into the camera and thus giving the blur effect of the scene at the back of the focused object. Therefore, the object in-front only has the sharpness aside others.

Next has the semi background blur f/5, which means that the front portion of the picture has the depth pictured sharp where the rest of the remained blur. Also notice the main object which still remained sharp from top to bottom.

Last two photos with the settings f/10 and f/16 are both similar. f/10 has it’s background even more clearer than f/5 but still the depth is not defined very clearly. But with the settings f/16, the depths of the background is highly defined and it is sharper than any other aperture settings here. And the settings like f/16 or higher is very good for landscape photos.

Wow! now you know how to blur the background of a picture when snapping, that’s a skill improvement for you. When I was young with no knowledge of photography (I was a dumb), then I used to imagine, how the heck the photo have such blurry effects until the day I learned this stuffs. And it is really a cool effect that most people want when targeting their photo in one object rather landscapes.

Now aperture and shutter speed are very closely linked with each other. If you set aperture to high then the shutter speed will increase at the same time and vice-versa. If you’re taking a snap of a faster photo with high shutter speed and in lower light then you can minimize the aperture or f-stop to allow more lights into your camera. This is really useful because not all pictures can be taken with lot’s of time and adjusts. Sometimes we need to take instant shots. And I tell you what, in the beginning, you will have trouble taking photos faster but once you get hold of it, then it’s just a piece of cake.

There you go, you’ve just learned it and I am done writing this article. Feel free to ask question if you’re having difficulties or if you think that I might have written anything wrong in this article. I would be glad to fix it.
