Chances are, you’re new to Photography world and have less idea about technical terms of camera & photography overall.
In this article, I’ll be explaining about Aperture as fast as possible.
And, let me mention it that I’ll be explaining about it based in Photography & Camera terms.
Let’s dive in.
In short, aperture is simply a mechanical hole in a camera that allows light to pass in & hit the sensor when needed.
We need it in a camera so that we can control the amount of light that hits camera sensor.
Aperture is made in such a way that, based on the exposure situation of the field, it can be opened up more or less.
So, if aperture largely opened, more light hits camera sensor thus we get bright image & vice-versa.
Aperture hole can be made bigger in darker environment and can be made smaller in brighter environment.
This picture should make much sense.
As you can see, larger the F number, smaller the hole becomes and lesser light is allowed to hit sensor which results in darker image which helps to maintain your exposure in bright-light conditions.
And, smaller F number means that the aperture opens up wide so that it could let more light to hit the sensor resulting brighter image.
Also, if you are shooting in smaller F numbers or on wide opening of aperture (below f/5.6), you’ll get that shallow dept of field also termed as bokeh effect or blur effect.
Now let me quickly wrap this up.
Aperture is a shutter that allows or blocks lights from the lens to the sensor by mechanically opening or closing itself.
When aperture is opened wide, you get brighter image, which is smaller F numbers.
And, when aperture is opened small, you get darker image, which is larger F numbers.
Also you can achieve that blur effect or shallow DoF (Depth of Field) if you opt. for smaller F numbers.
So, that’s everything (basic) you need to know about the Aperture.
