Manufacturers have been improving the battery in their Android terminals for years. For this, they have used technologies such as artificial intelligence, or direct improvements in their hardware. Double and triple cameras are the order of the day , something that, in my view, is more a marketing strategy than a real improvement, although they really add value, although not as much as we can think.
In spite of what DxOMark says, page that has shown rollerblading on more than one and two occasions, the camera of the Google Pixel 2 XL is still the best for many YouTubers and fellow techies , since it has the best processed currently, as well as an unparalleled portrait mode. The rumors point to a Pixel 3 XL that will bet on a single camera, something that will be a blow to the rest of the manufacturers.
As a photographer, what I value most in a mobile photograph is the dynamic range, the sharpness, the correct exposure and that the portrait mode is realistic . Currently, absolutely all high-end phones suffer from overexposure, leaving the skies burned whenever there is sunlight with our backs to us. The Google Pixel 2 XL is the only terminal that does not overexpose the skies , and whose front camera has the same dynamic range as the back one. On the other hand, his portrait mode is simply spectacular, since not only is he able to distinguish background and figure, but also Blurs the elements in front of the main object , for sample, the photo below.
The portrait mode of the Pixel is the only one allows me to take cover photographs without being noticed that they are shot with a smartphone , since the portrait mode of the other high-end always leaves some imperfection on the way, while the trimming of the Pixel is 100% accurate. This shows that no secondary sensor is necessary to obtain more information, since Google’s computational photography is above this , and with a single camera is more than enough.
Also call the attention that the Pixel 2 has an 8 megapixel front camera with aperture f / 2.4 , and make better photos than mobile phones with more than 20 megapixels of front and apertures f / 1.7 / 8/9 … The sample that the software can with the hardware , and that artificial intelligence is of little use if you limit yourself to raise the saturation of the image and little else.
That the Pixel with a camera makes better pictures than other phones with 2 or 3, does not mean that having more cameras is not useful. In the case of the P20 Pro, zoom 5X is a real joy , being the only way to carry this out their secondary cameras. However, it is worth considering what is currently used, the zoom or portrait mode? Taking into account that the public that changes the most mobile and values functions such as portrait mode for petarlo on Instagram, it is worth considering how many users actually use the zoom in their photographs.
If we rely on simple traditional photography, think about how much portrait photography there is currently and what is its relevance, compared to macro or zoom photography . Having said that, I think we should reflect on the true importance of software in mobile photography , before getting carried away by megapixels and number of cameras. These are aggressive marketing strategies that manage to fulfill their purpose well, creating some ignorance in the users.
