iOS 15 will remedy one of the most annoying failures of the iPhone camera: stray lights. It will be thanks to the post processing that will be applied once the photographs are analyzed, but being able to say goodbye to those annoying green orbs that appear on more than one occasion among other types of flashes and flares is great news.
What are stray lights
Stray light is defined as all light entering through a camera lens in an uncontrolled way. A phenomenon that, although it may have a creative part that is of interest on specific occasions, usually poses a significant problem because it generates a series of flashes, flares, halos and even orbs of different colors that annoy the final photograph.
About how all this is produced or what is the reason that causes the stray light, it must be said that there are several, but always when there is a strong light that falls directly on the objective. If it is somewhat dirty, it does not have a sun visor, it uses low-quality filters and the occasional other case, then it ends up appearing.
That is why it is important to take care of the lighting sources of a scene when we are going to take a picture, although sometimes even doing so they appear despite the fact that in the preview we do not appreciate any problem.
The iPhone and the "Green Orb"
In the image above you can see the green orb. In the one below, already processed with the latest version of iOS 15, it disappears
The iPhone has suffered from stray lights and Green Orb throughout different generations, becoming a very annoying problem. Especially for users who were unaware of this problem, it became frustrating because paying the price of an iPhone and seeing green or other colored orbs appear in the photos left them wondering if the camera could be defective or not.
Well, Apple in the latest beta of iOS 15 has introduced a improvement in image processing that allows these defects to be eliminated via software. They have been able to verify this on Reddit and that the person responsible for the development of the Halide application has later shared it again for everyone's knowledge.
This solves an annoying bug in the iPhone camera that, as we said, has accompanied its users for several generations of the product. Now it is only necessary that the algorithms and analysis carried out by the processor software continue to improve and learn how it is created and how it can be removed efficiently no matter where it "falls" in the final photograph.
There will be situations where, due to its similarity to the background or object on which it appears, it cannot be removed, but if it does disappear in a high percentage of forums, it will be enough. Of course, this may revive that debate about who is truly responsible for good photographs: the user or the software that processes and interprets the scene as it thinks it will be more attractive.
At this rate, the computational photography It will be so powerful that it will even end up determining the most attractive frame for any scene. So you just have to open the camera app, shoot and let the software take care of everything.
