Dual camera
Dual camera phones were the sensation of 2017, almost every single smartphone started to have a dual camera set up and they claimed to avail depth sensing using these cameras. Now just like a human eye you can focus on a single object and blur the background using 3D viewpoint, and create a bouquet effect. This was great right? because you can now capture a very good looking image without having much knowledge of photography skills and the image will look like it was captured with the DSLR. Now you post these pictures on social media and people will be clueless and surprised, you will collect a lot of wows, right?
A brief history
Now let me tell you a brief history of the dual cameras on phones then you will probably get me. It may surprise you but the first dual phone camera was announced in 2017 and it was a Samsung flip phone which was designed for the Korean market. The first dual-camera smartphone which managed to be launched was HTC EVO 3D. At that time the main goal of having a dual camera on a phone was to capture 3D videos and images. and at the time this river camera city was considered to be a very revolutionary feature being in a smartphone, but under the curtains, companies were compromising the other features of the smartphone with the dual-camera setup. Because of not very good performance, these phones didn't get the chance to be a hit.
The scam
What if I tell you that in spite of having all that you are probably being scammed, yeah you got it right, there are 80% chances that you are being scammed, especially if you are using a mid-range or lower mid-range phone you are probably being scammed. It doesn’t make sense?
Sorry, we got debited from a topic so we were discussing whether these dual camera phones really something to think about or this is a very well executed scam. as I have mentioned earlier that dual-camera setup in a smartphone gives the smartphone power to sense the depth and produce a really good looking bokeh effect in the image. For those who don’t know that what is a bokeh effect, it is the effect which makes the object in the centre in focus and everything else blurred, like a DSLR (very close to DSLR). You can not fit the optical property of a DSLR into a smartphone so this artificially created effect produces images really close to that of a DSLR. The smartphones like Huawei P10 and Samsung galaxy note 8 fulfil this requirement really good. But it is really bad to say that almost 60 to 70 per cent of the phones we have currently in the market have apparently fake depth sensing.
The affected phones
This thing was observed in the mid-range and lower mid-range smartphones, rather providing actual hardware to create depth-sensing they used simple image processing to create that effect, segment the object in the focus and blur everything else. Simple right? But the results they create can be really far far away from the concept of depth sensing.
To check your smartphones, if they are having the authentic and working, just cover the non-primary camera and try to capture a bokeh image, if it workes then know that you are scammed. Many companies have made these type of smartphones, they just advertise the technology and do not provide it in the phone. It’s not that they don’t have access to such technology, its because they don’t want to provide it in the lower mid-range phones. Many smartphone companies provide it in their high priced phones and not in their low priced phones.
I say if you are not able to provide the feature then why to lure people by advertising it.
