What is each of the three cameras of the cell phone and how to make the most of them


Following the launch of several consecutive models from LG, Samsung, Motorola and Alcatel, the three subsequent cameras became the standard for mid-range equipment sold in the country. Far from being a large lens divided into three parts, each one is designed to offer a unique feature. At this point many ask: What is each one for? Do they run simultaneously? Is there a specific one for portraits, landscapes or group photos? Also, what is the function of the depth sensor and what does it mean wide angle or macro camera. The specialists explain how to make the most of them.

A better camera is the main excuse to move from cell phone. In recent years, the turning point in the evolution of mobile photography was the integration of multiple sensors in the devices to make up for the lack of zoom and achieve a greater variety of results.

The combination of these lenses opened the door to the professional world of night photography, background blur, face detection, the ability to achieve small details at very short distances (macros) or the ability to highlight what is hidden in the shadows or in broad daylight.

The peculiarity that the experts emphasize is that, a greater number of “holes” in the back, does not have to affect the final result of the photos. It only depends on it the quality of the lenses and sensors that forms each of the cameras.

The three cameras that incorporate most mid-range mobiles are the main call, depth and wide angle. And although many times, through software, they can work together, each one is intended for a type of photography.

“The main camera It is the one that uses by default the cell phone for instant photos. Incorporating Artificial Intelligence (AI) allows it to recognize scenes and Automatically apply settings to get the best possible photo. In some cell phones, this AI allows highlighting a particular color and leaving the rest of the scene in black and white ”, summarizes Martín Errante, product manager for Motorola.

Moto G8 Plus. It has three cameras: a main one of 48 MP, a depth sensor of 5 MP and a wide angle of 16 MP, but that is for the exclusive use of the video mode.

The depth chamber works in conjunction with the main and generate a blur effect (bokeh) in the background of an image, highlighting the foreground or vice versa. If the subject is in focus but the foreground or background is blurred, the photo is said to have a limited depth of field. If almost the entire photo is in focus, the photo has a maximum depth of field.

This feature is already present in intermediate equipment such as the Samsung Galaxy A20s, the Alcatel 3X, some models of the Motorola One line and the recent LG K50s. Little by little, the trend shifts to entry teams, such as the recent Moto E6s.

One of the ones that stands out is the classic Motorola G8Plus, with three cameras: a main one with 48 MP, a depth sensor with 5 MP and a wide-angle with 16 MP, but that is for the exclusive use of the video mode.

The Samsung Galaxy A71 has four rear (64 MP f / 1.8, 5 MP macro, 12 MP wide angle and 5 MP depth). The Macro Cam function achieves sharper detail photos, especially for photos of dishes or nature.

“The real benefit of the three cameras is that now it is the smartphone that adapts to take the best photo and not the user, providing greater flexibility to each situation. The incorporation of wide angle camera It produced that, with just one button, you can expand everything you see, without having to run or bend down so that the group of people or landscape enters the picture. The third camera allows adding depth and taking photos with a bokeh effect. This effect before you could only do it with a professional lens“warns Sergio Jung, product manager of the LG cell division.

The main purpose of a wide angle lens is to achieve -between 60 and 120 degrees- a greater depth of field, which is the area in front of the camera that appears focused. The idea is to widen the angle of view and, despite being at a certain distance from the lens, make sure there is room in the frame for everything you want to photograph.

The LG K50s incorporates a triple rear camera of 13, 5 and 2 MP whose sensors are intended for standard photos, wide-range captures and the depth effect that allows an artistic blur to be made in the photos.

Most of the equipment, from the camera software, allow you to select some of these three options manually. While some models, in a single shot, are capable of combine all lenses to achieve creative results.

Already in the most advanced lines, some cell phones incorporate more than three cameras, such as the Samsung Galaxy A71.

On the more expensive phones there are even more features. “The function Single shot, through the AI ​​technology of the Galaxy S20 you can capture and compose, in a few seconds, a mosaic with different styles of photos and short videos, such as live, cropped and ultra wide focus, among others, and thus take advantage of the best shots of each batch ”, says Eliseo Outes, head of product at Samsung Electronics.

Alcatel 3X. The first of its cameras is 16 MP and is capable of automatic adjustment. The second is an 8 MP wide-angle camera that offers a 118-degree field of view. The third is a camera to work depth and is 5MP.

The lens telephoto lens, continuing in the territory of the high range, it is the one that facilitates the approach of the lens in a clear way using the camera’s own optics and without resorting to the mobile zoom. In other words, it does the opposite of the wide angle, bringing closer what you want to photograph without losing focus.

“The Galaxy S20’s large image sensor causes the camera resolution to increase significantly, obtaining more detailed images with additional flexibility to edit, crop and zoom. The 20 and S20 + have a 64MP camera, while the S20 Ultra has a 108MP camera, “explains Outes.

Another widespread myth in photography is that of megapixels (MP), considered as synonymous with better photos. The amount of MP – allows you to estimate how much an image can be enlarged without losing sharpness – speaks of the resolution of the camera, a parameter that affects the size of the image and not its quality.

The important thing is the size of the pixels, the small dots that make up a digital image. “We can combine them with each other to create larger pixels, with greater sensitivity to light to obtain sharper photos,” Errante summarized, explaining Quad Pixel technology, which brings together four in one. “This allows for good photos even in low light environments,” he said.
