Almost all smartphones come with a Front-facing and Rear-shooting camera.

A smartphone comprises up of three main parts:

The sensor which detects light

The lens the component in which light comes through & the image processor

How it works actually?

1 -The user or smartphone focuses the lens

2 -Light enters the lens

3 -The aperture determines the amount of light that reaches the sensor

4 -The shutter determines how long the sensor is exposed to light

5 -The sensor captures the image

6 -The camera’s hardware processes and records the image

The megapixels on the smartphone are still an important part of the camera, it carries less importance than it did a while back. Instead, the primary limiting factor is the camera sensor of the phone and how sensitive it is when light passes through the lens.

Each sensor behaves very differently in a different smartphone, so every single image or video that you capture will be a variation of contrast, color accuracy, saturation and several others compared to a different handset. Most camera apps have manual settings so you can capture an image or video based on your own settings, but most devices don’t have such an extended list of controls.

Since smartphones have small sensor sizes, they tend to perform badly in low-light areas. This is an area where camera sensor manufacturers have worked incessantly to improve considerably, but they have a long road ahead of them it appears.

How focusing works?

A mechanism that restricts how much light passes through the lens and into the camera itself in order to control what’s called depth of field, or the area of the plane that appears in focus. The more your aperture is closed in, the more of your shot will be in focus, and the more open it is, less of your total image will be in focus.

Wide open apertures are in photography because they allow you to take photos with a awesome blurry background, highlighting your subject while narrow apertures are great for things like macro photography, landscapes, portraits etc.

The ƒ-stop is a ratio of the focal length divided by the aperture opening. For example, a lens with a 50mm focal length and an opening of 10mm will be listed as ƒ/5. This number tells us a very important piece of information: how much light is making it to the sensor.
