For years we have seen a clear trend in smartphones and that is that the back of the devices, although sometimes also on the front, has two cameras or more. This for some may have a clear reason, but for many people it becomes a mystery to be solved and this time we are going to clarify it.
To reach the conclusion that has caused manufacturers to put more and more lenses on the back of devices, we must look at mobile phones from 2017, for example, when the Samsung Galaxy S8 and its only 12 Mpx lens It was the most advanced that we could find on the market, with photos that were good, but, however, they do not reach the current levels, where more lenses have been needed.
Multiplying the possibilities of mobile
With a single camera, the smartphone could continue to take very good photos, but it would not offer us the diversity of options that we have today. This is the main reason that manufacturers have been adding more and more cameras. The need to compete with professional cameras has led them to this.
Photographers have at their disposal the option to change the lens of the camera, to achieve a different focal length or to modify the angle of view, while on mobile phones that was only possible with accessories that were not at all practical. Since the space available on the back was sufficient, all kinds of lenses began to be added, so that, on the screen, we only have to choose the one we want to use at any given time.
Therefore, the clear and concise explanation that leads us to understand why phones have two, three or even four cameras, is based on the options they offer when taking photos or videos.
What each of them can do
Maybe you didn’t even know it, but each of those cameras in the smartphone module has a purpose. From now on, in addition to knowing what they offer, you will know what each of them does, we are going to explain their advantages in a concise way. In this way, depending on the situation in which you find yourself, you can get the most out of your mobile.
Standard/Main
We start with the camera that all mobiles have integrated for many years and that is concerned with achieving the best result in all situations. Its strong point is usually the resolution , in addition to the aperture, to capture the highest level of light possible and that the photos come out well day and night.
wide angle
It is the second most popular lens in smartphones, since it offers a very different image than the standard one. The wide angle has many uses, achieving with the largest field of view , among other things, photographing or recording landscapes that otherwise could not be fully perceived at a glance.
Depth
It is one of the cameras that first began to be integrated into smartphones and that over time has lost prominence since others have adapted their capabilities. It is above all dedicated to recognizing the depth that was from the terminal to the object in the foreground, to make the striking portrait effect that many know.
Zoom
The ability to get closer to something through the mobile cannot be missing, for which the optical or digital zoom is a key factor. It is increasingly necessary in photography, allowing distance not to be an impediment and the greater it is, the less blurred the image.
Macro
Contrary to the zoom, in this case we have to get closer to a small detail up to approximately 3 or 4 centimeters, being able to see each filament of the fabric or composition however tiny it may be, observing more than the human eye in some cases.
