Users of the beta version of iOS 15 have discovered that the camera application is now able to eliminate the effect of “lens flare”, or lens flare, when we photograph scenes with a direct light source.
It is very possible that right now, among the photos that you have stored on your mobile you have one with that failure. It is easily recognizable as a “halo” of light, or a point of light that appears in a part of the image. It normally appears when the sun is low enough to hit the lens, hence the circular shape it usually has.
In the case of the iPhone, it is more common to find this fault as a green light, which appears on the opposite side to the light source. For example, in the following photo , posted by Reddit user u / Doubleluckstur, we can see that on the left there is a green area; It’s the kind of thing that doesn’t bother you that much, until you realize it, and then it’s the only thing you can see.

But with iOS 15, it seems that Apple has achieved a breakthrough that allows us to eliminate these failures automatically, and without us having to do anything. When the user first took the photo, they observed the existence of the “lens flare”; but later, he reviewed the photos taken, he realized that it had disappeared. It wasn’t that his mind was playing tricks on him, but that iOS had applied image enhancement algorithms .
Although Apple has not officially confirmed it, everything indicates that a new algorithm is focused on detecting and eliminating flare from images, especially if they aesthetically ruin the image. This has been confirmed by other users of the iOS 15 beta, although it seems that the algorithms do not work the same way in all situations.
For example, depending on where the flash appears, the algorithm may not detect it, or decide not to eliminate it; on more complex surfaces, such as the bark of a tree, the flare remains, presumably because the system is unable to remove it without affecting image quality.
Instead, the flashes that appear in the sky, grass or other surfaces are eliminated. It also seems to depend a lot on the light source; if the algorithm detects the sun, it is more likely to eliminate the flare, and not to eliminate it with artificial lights.
According to the developer of one of the most popular camera apps on iOS, Halide, this is “great news,” although not everyone may be as happy. Many photographers look for the flare effect in their creations, and it can be a hassle for iOS to remove them automatically and without prompting the user.
