That is for sure interesting. It almost looks like a flashlight being pointed at the ground, even though I know it isn't. Refraction or even reflection of sunlight comes to mind too. But what is the cause?

From the size, blurriness and visibility when in shadow i'd say it's a small dent in the covering glas of the camera.

it is a new drone, it is untouched, i took off only from my hands, so, how do you explain that in other directions does not appear that effect? and another question...why it is exactly on the shadow ? Thanks

What's strange is the very end where you're dropping it down to land.  The white spot goes away and the shadow of the drone appears in the exact same place.  It seems very unlikely, but I wonder if it's some auto-exposure going crazy on the shadow of the drone.  It would explain why it's only there with the sun to your back.  I can't imagine that shadow could cause that from the high elevation you were at, but it sure seems odd that when you dropped it at the end, you could not see that shadow at all until the white spot went away and then you're left with the drone shadow.  I'm curious to see what's causing this once it's been determined.

It's a well known phenomenon called "Heiligenschein" and it has nothing to do with any DJI specific problem. It was already mentioned before here in the forum. https://en.m.wikipedia.org/wiki/Heiligenschein

This happens often. If anyone look at the footage they will see this. I have noticed this
with all my drones. There's nothing wrong with your bird.

Very odd,  it doesn't look like flare,  more digital.  Have you tried a different SD card?

I've answered this question in another thread: https://forum.dji.com/forum.php? ... D712%26typeid%3D712

Paste from the other post:
I noticed this in many drone shots and videos, when the shadow of the drone fall in the scene,specially over grass and homogeneous foregrounds. It´s an optical illusion created by the edges of the shadow which dissolves in to the surrounding. It´s called Heiligenschein.
https://en.wikipedia.org/wiki/Heiligenschein

I thought it could be caused by the internal camera software compensating, but apparently if you look with your own eyes yo will see it too.

Interesting topic, I found an older thread here talking about this subject.

Good luck getting any more info from DJI.
Did you check the Wikipedia link?

It shows you how this is also perceived from inflated balloons, with naked eye, no camera...  From airplanes... basically this has nothing to do with DJI is an optical illusion.

Is not present only in movies, but in real life too... if you are there you see it with your own eyes too.
Is also not only for drones, I repeat, any camera, flying or not, and even without using a camera at all but using your own eyes. Is an optical illusion.

DJI doens't come around to give opinions about optical illusions, or other matters but to assist with certain issues or requests, since this is not a problem with the Mini or any of their products, why should they?

I mean I'm not trying to be a "know it all", but help, the info I provided closes the question or doubt about this phenomenon completely.

You obviously haven't read the links I provided since this old post, asking the same question you did, has an answer from DJI Official : https://forum.dji.com/thread-109188-1-1.html

DJI Susan replied: As discussed above, please try to avoid shooting with sun behind.

That's DJI "Official answer".

For those of you wondering why when the drone is near the ground the shadow looks normal, this is because the effect only happens when the shadow is blurry, at the edges, if the drone is let say in the floor, the shadow is sharp, so no effect, the further it gets from the reflected surface (floor) the more the shadow edges soften and the more the "Heiligenschein" effect will be noticeable.
All explained in the Wikipedia article.
