iOS 15 will remedy one of the most annoying iPhone camera glitches : stray lights. It will be thanks to the post-processing that you will apply once you analyze the photographs, 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 any light that enters the lens of a camera in an uncontrolled way . A phenomenon that, although it may have a creative part that is interesting 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.
Regarding how all this occurs 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 hood, it uses poor quality filters and some 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 photograph, 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”

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 what an iPhone costs and seeing that green or other colored orbs appear in the photos left them with doubts about whether or not the camera could be defective.
Well, Apple in the latest beta of iOS 15 has introduced an improvement in the processing of images that allows to eliminate these defects via software. This has been confirmed on Reddit and that the person responsible for the development of the Halide application has then shared it again for everyone to know.
This solves an annoying failure 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 that the processor software performs is improving and learning how it is created and how it can be eliminated 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 reignite that debate about who is truly responsible for good photographs: the user or the software that processes and interprets the scene as they think it will be more attractive.
At this rate, computational photography will be so powerful that it will even determine 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.
