What causes "The Blob"?

[GadgetGuy]

Nothing whatsoever to do with the color of the drone. Have a look at the page linked to that talks about opposition surge. Here is a brief summary.

When filming irregular surfaces there will be some shadows on the surface (even very small ones) everywhere except where the light is reflecting directly back at you - no shadows there. That, by definition, is when the sun is right behind the camera. Everywhere else, the shadows (even small ones on rock or even grass) will average with the reflected light to an intensity less than that area where all light is reflected straight back with no shadows.

Hope that helps.

Thanks for the clarification!

The same thing happens when you fly anything, planes, hang gliders or whatever, the same exact flare. It is normal.
