There's an easy way and you won't need any trick: don't shoot backlight!
If you need that precise angle of view, shoot it earlier or later when the sun is not facing you, this is also a photographer's contraint: control the light…
Another way would be to add a lens hood, but that might be difficult on a drone…
Also, those cameras are usually set to shoot wide open (with such wide angles and shooting distance, that is not a problem for the depth of field) if that's possible, try to stop down (light is not missing there) it may diminish the bad effect…
@Asher Kelman: Post your methodology, I'd love to see how you can fix that…
I have been asked to propose sculptures for a bluff facing the Pacific Ocean. So I asked the City to allow me to first build a 3D model, for which I need a drone to get me a set of overlapping stills for photoprogrammetry!
I have engaged a company who will provide the drone and an experienced pilot. I have no expertise here and the software, Agisoft Metashape or Pix4D needs
perfectly focused sharp, high contrast, overlapping pictures.
I was surprised when they couldn’t tell me the exact time of the planned shoot, off hand, without going back to his computer and calling me again!
It was explained that they need to first look up the sun angles, so as to set set the time of day exactly when the sun is closest to being high above the location, so there will be no long shadows.
.....and also, don’t expect “artsy drama”, as they never fly into the sun for the pictures I need!
I thought I could also have dramatic pictures of the coast line, at dawn or at sunset, so was so disappointed!
I was told bluntly, “Choose: do you want your well-exposed high contrast detail-rich pictures
....... or you want “art”?”
So you are totally correct, as expected.
The set of pictures technically perfect, I need, cannot easily include “flying towards the sun”, low in the sky.
So for
that, he would provide, (at several times the cost), a larger drone with a medium format camera or a “Red”, with extra wide dynamic range, but couldn’t even then guarantee I’d be satisfied.
Knowing this, I, personally am not at all qualified to take charge of a drone for what I need, LOL!
But I did, nevertheless, try my hardest to correct the O.P. image, above and failed!
