As far as phones are concerned, camera quality is one of the important features for a user when it comes to selecting a new smartphone. Everyone wants to be able to have a very clear image depicting that amazing lifetime experience they have had. In recent times, Smartphone companies are launching their phones with dual and triple rear cameras. There has been a lot of development in the field of machine learning and artificial intelligence in a few years. Thanks to this, the Triple Camera in the Smartphone is now capable of taking professional photographs. The Tri-camera in the rear can give a very clear photo in low light. Also, by taking the desired details with Wide Angle and Zoom, it is helpful to take a lot to take clear snaps.

In addition to this, Triple rear cameras are very useful for highlighting objects or faces as compared to the background. For example, the Night mode in Huawei P20 Pro enables you to take photos for six seconds of exposure time and the wide angle mode on the TECNO Camon 12 pro enables you to take images with a very wide coverage angle. In summary, these dual, triple camera gives the user the facility to click beautiful pictures.

Now lets us elaborate some basics supposing a phone has a specification of rear camera as : 32MP f1.7 aperture (Main)+8MP(Ultra wide)+5MP f2.2(Live Focus) and see how these three camera affects photography.

What is aperture?
Aperture is a hole in the lens through which light enter into the camera. If aperture size is large then incoming light is more compare to the one whose aperture is small. Aperture size is measured in terms of ‘f number’ or ‘f stop’.

All of us have seen the specification of camera given above as an example, there is a no. written like f1.7 that is the aperture value of the lens. ‘F’ is always written before the no.

Depth of Field (Dof)

Depth of field is a distance between nearest and farthest objects in the image. That is the distance between foreground parts of image to the background parts of image. Dof can either be large or shallow.
The lens with small aperture size has large depth of field. in this case we will get a whole image in focus. There is no background blurring effect.(Main Camera)
The lens with large aperture has shallow depth of field because that lens mainly focus on the area that we want in image and background part got blurred. One benefit of large aperture size is that in night we get a clearer picture because in night light entering in the camera is more. (Live focus)

Wide Angle Lens:
Today all camera phones are coming with ultra wide angle (up to 1200 ) lens. How this ultra wide feature of lens is achieved? The answer is focal length. The lens with smaller focal length provide wide angle pictures. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it.

Other benefits of Triple cameras include:

1) Higher Resolution Image: If you have a higher resolution camera then it will give you a very good image which will be worth printing. You can also use this photo of Professional Quality for zooming and cropping. Despite much zoom and distance, you will get many details in your images.

2) Better low light Image: In this Tri-camera system, an additional camera improves the condition of the light in the photo. A high-speed monochrome sensor with better light sensitivity is capable of providing a good snap in very low light or at night too.

3) Multi-Aperture for accurate and clear image: Just like high-resolution and low-light sensitivity is necessary, a switchable aperture is also beneficial in the camera. Aperture is an important factor that determines how much light the sensor has to reach. Here, more light means to give a bright picture in the dark, that too with low noise. Telephoto or wide-angle lenses are also using this technique.

4) Zoom further to capture more details: In the triple camera system, the additional camera is able to zoom more. For example, the camera of HUAWEI P20 Pro offers a 3x zoom. That higher zoom means getting very good details even with distant captures.

5) More Stabilized Image: If you want HDR images with more exposure, and without the risk of getting a blurred image, then a dedicated monochrome sensor is the best option for you. The triple camera helps to make your image more stable.

6) Better Portrait with Bokeh and Depth detection: With soft-bokeh and background blur effects, you succeed in getting good portraits. Although it is possible to do both with the dual camera, a dedicated third camera can provide better results by providing more depth to your images.

7) Wide-angled Snaps: Wide-angle images have been one of the favorite options for most of us. In such images, a wider view can be captured in the same frame. Often with zoom, you can’t fully capture your desired large view. Here, the same wide-angle feature can help you a lot to capture a wider snap.

It is to also note that to get a beautiful picture, some other function also matters like distance of camera from the subject and other settings. Here only the basics that smartphones companies have specified in their camera were discussed.

Very educative

Ftc dedicated to all that believes that convid19 can be defeated with good hygienic practice and social distancing.

seunlayi:
Very educative

At least those people using iphone 11, can now know the Function the three camera(s) at the back of their phone. All thanks to the poster

Nice one

Very Educative. Nice one Op.

At what point does the number of cameras Bec me a gimmick? Besides wide angle lens, can't they achieve the rest with software instead of packing that many cameras?

lol, well it's a good thing they'll learn the uses of the triple cameras their phones carry and not just them but every triple camera phone user too

Phones now help in so many ways for my businesss.

actually theres been a huge advance in camera technology in recent times, but instead of creating more cameras wouldn't it be a nicer idea to just make one camera that can carry all these features?

i dont know sha but i feel one of the good advantages of this triple camera idea is just the wide angle shots it could give.

nice info @op, most triple camera phones i know dont fall short when it comes to producing great photos

I hope you are not talking of Tecno/infinix

Nive one OP, you broke it down well.

Educating thread

Camera explained in detail. Thanks op

shiftback:
At what point does the number of cameras Bec me a gimmick? Besides wide angle lens, can't they achieve the rest with software instead of packing that many cameras?

like you get. I don't seem to see the essence behind packing a lot of cameras

Multiple camera phones is overrated, I won't be swayed, soon we will go back to single camera phones again

Up to a point, one camera with software enhancements produced great results. We saw that with Google's Pixel phones.

But multiple cameras have the advantage that each lens can do one thing better than the other. e.g. one lens is dedicated to macro (close-up) shots, while another is dedicated to telephoto.

It is like having two professionals in different fields instead of one man who is good at both fields. More often than not, you get better results with two separate men who experts at their different fields.

Which is why in the last few years, Google Pixel cameras have fallen behind the competition from Huawei, Samsung, Xiaomi, and OPPO. Google is now making cameras with multiple lens too and trying to catch up.

I hope that explanation helps. Cheers.

Nice one OP

Thanks for post, I've learned something new

Thanks for this, My Xiaomi note 8 has 4 camera lenses and apart from the main camera lens I really did not know what the other 3 are for till now.
This present young generation like taking pictures.
For some of us Battery life, Mails and App multi tasking matter more than pictures.
Sometimes I can go weeks without taking any pictures on my phone.

This is the information tat i've always wanted.

This not our priority now joor

Enlightening
