Manufacturers of flagship devices in the old-fashioned way build the description of new products around this indicator, but it itself grows more and more slowly from year to year, in contrast to the extensive list of additional options. And this is reasonable, because the more pixels, the wider the range of potential problems for the typical user.
Each megapixel is a solid amount of information that needs processing, storage space, transfer capacity, etc. When watching HD video, our eyes should be able to perceive approximately 2 million individual objects, and if we sit down at a 4K-capable display, their number will exceed 8 million. Such a breakthrough of data is objectively required only in cases where it is necessary to meticulously display all the details of a complex image. For example, a photo for a National Geographic magazine – 10 megapixels will be enough.
If a non-professional photographer picks up a camera with a matrix of several tens of megapixels, the gadget will conscientiously record all the flaws of his work in the pictures. Whether it is an excessive amount of artifacts with inept use of lighting, which turned out to be monstrous blur due to trembling hands, or unnecessary small details that were deprived of the chance to get lost against the background of the main objects.
The resulting image turns out to be so large that a spontaneous photo shoot instantly fills the modest limits of a free “cloud”, and for publication on social networks it has to be deliberately cropped, removing those megapixels with your own hands. Which, overnight, from the desired ones became superfluous.
How many megapixels do you need?
For the average user, whose task is to take photos and videos for Instagram and other social networks, an 8 MP camera is enough. The fact is that almost every cloud-based photo service (including Instagram, Vkontakte, etc.) automatically reduces the quality (compresses or reduces the size) of the original picture (or video) upon publication.
Why do you need a lot of megapixels
An increase in the resolution of the camera matrix is justified in cases where the result of its work will be presented over a wide area. An advertising poster with an area of several square meters, a print on the entire wall of a boutique, a printout of a character’s figure in full growth.
It is important that an ordinary, average smartphone owner runs the risk of facing such a task well if once or twice in his entire active life. And troubles with a lack of memory space and traffic overruns are familiar and relevant for everyone.
Still want an iPhone with a 20MP camera?
Below are photos taken from the Apple website showing the capabilities of the camera from the iPhone 6s to the iPhone 12 Pro Max (12 MP), of course, with beautiful places and competent use.
