The camera tech 📷#2 Aperture. 🔥

In our previous article, we understood the megapixels in cameras and clear our myth about the megapixel count.
In this article, we will know about the next and very much important component of the camera which is the Aperture of the camera.

The aperture is the same as the pupil of the human eye,
In the human eye, there is a pupil which is like a hole that allows light to enter the eye by which we can see.
The aperture also performs the same function it allows the light to enter the camera and reach the image sensor.

So, now we will know about the aperture.

What is Aperture?

The aperture is defined by the size of the opening from which light can enter in the camera.
Aperture is measured in f-stops, which is a ratio of the focal length divided by the opening size. 

So the smaller the f-stop the wider the opening and therefore more light can reach the sensor, which results in better low-light pictures and less noise.
As you narrow the aperture by a full “stop” —or power of the square root of 2 (ƒ/2 to ƒ/2.8, ƒ/4 to ƒ/5.8, etc).

Smartphone cameras are positioned very close to the lens as compared to DSLR cameras. A camera’s focal point is the distance between where the light convergences in the lens to the sensor, smartphone cameras have shorter focal lengths than DSLRs.
As we know that the aperture equation is the focal length divided by the opening size, this helps to explain why phone cameras have a wider aperture than most DSLR lenses, even though they are not necessarily better at light capturing.

That is all about Aperture, I hope you have understood about Aperture.
