What is a 108 megapixel camera phone for?

At the end of 2019, the world's first phones with 108 megapixel cameras arrived on the market, the Xiaomi Mi Note 10 and the Mi Note 10 Pro, in fact, the first of these just arrived in Mexico a few days ago. However, I just started the year and we already have another 3 phones with a 108 megapixel camera, such as the Xiaomi Mi 10, the Mi 10 Pro and the Samsung Galaxy S20 Ultra. Situation that indicates that the fashion of the 108 megapixels could continue to expand to other manufacturers throughout the year.

Ms is not always better in photography

We have also wondered if it really works
that a phone has a camera with 108 MP, is it useful? What benefits does it have?
Is it a marketing trick? Before answering all these questions
we must mention that not having more megapixels we have a better photo,
for this many other factors come in, such as the size of the pxel, the focal aperture,
image processing, etc.

Therefore, the first thing you should discard is that one of these phones will make a better picture than a 48, 64 or even 12 megapixel phone. What is a fact, is that a photograph with so many pixels will allow you to have larger images that we can print on advertising posters without problem.

The issue is that people who do not advertise
will use a phone to capture an advertising image, because that is why
They use semi-professional rflex camera. On the other hand, the sensors of the
108 megapixel phones that are so far are 0.8 microns, that is,
They are basically the same size as other sensors on the market, so
the 108 megapixels are also not taken advantage of if the sensor is no more
large, because the larger the sensor, the greater the amount of light that
can enter, and in these cases the photographs with poor lighting will not be so
Good if you want to take them with a quality of 108 MP.

For this reason all manufacturers use a function to merge pixels, thereby mixing several pixels in one, in the case of Xiaomi the firm uses Pixel Binning, which allows to join 4 pixels in one, giving photographs of up to 27 megapixels but with a size of 1.6 microns, that is, less megapixels but more light, while the S20 Ultra can do the same, but mixing 9 pixels in 1, obtaining photographs of 12 megapixels of 2.4 microns.

Now, a 27 megapixel photo is still a lot
for a telephone, especially if the only thing we are going to do is publish it in
social networks or see it in Google Photos, so here it is more convenient
an image of 12 megapixels, but with more light.

The problem of storage and processing

Another detail that we must consider is that the photographs weigh much more when the resolution increases, for example, in the Xiaomi Mi Note 10 the weight of an image of 108 megapixels is 20 MB, which although it is not something that will cause problems With the storage of your phone, in the long run you can force yourself to erase your images to save some space, and if on the other hand you are one of those who like to upload these images to Google Photos, they will not be uploaded with this quality, unless that you occupy your storage space, and not as such the unlimited Google Photos.

On the other hand, a phone with a sensor of this size
it requires more processing work to take the picture, and this is
something that shows in the Xiaomi MI Note 10, because the camera application is less
fluid compared to other phones of the brand. It is not a difference that
annoy, but what users are going to notice are accustomed to using other
Camera applications that work quite quickly.

So there is no advantage of a 108 megapixel camera?

Yes and no. Yes, if we need very large images or if we can merge them to have a photo with more light, which in conditions with poor lighting help in a remarkable way, however, in the telephones it is not common that we are going to see larger and larger sensors that we allow you to take advantage of the resolution without losing the light collection.

Now, for most users a 48 or 64 megapixel sensor
It may work much better than one of 108, especially for casual photographs.
The 108 megapixels on phones are not bad news, but neither are they a
function that revolutionizes mobile photography, so depend on each user
Choose whether or not a phone with these features suits you.
