I forgot to add in my demonstration that I consider (an estimation) the bush at the right on my pictures to be about at the same distance as the background trees on Ty's photos (70-80 feet away).
The drone IMO is further than the background trees.
In fact, we have to consider three things (with all the camera specification, of course):
- The distance of the midground/background object
- The resolution of the picture
- The distance made by the photographer between the shoots
before drawing assumptions about the real size of an object.
In my GIF example, the pole line have exactly the same pixels size at a poor resolution but
NOT at the max resolution.
If the drone were closer than the background tree, I guess that a differences could have been detected in the numbers of pixels of it, between KK and LL; and I also think it's possible even in a poor resolution (again depends of the distance of the drone and of the resolution of the photograph).
However, like you noticed it, it's difficult to count the drone pixels since it's tilting and rotating.
I'm really curious to see if there's differences between KK and LL drone size in Hi-res. picture.
IMO, yes, or the drone is really really BIG!!
