(1)Sunset in a rainy winter day.
There is a lot of post-processing in this picture (Mavic Pro, 12Mp, ISO 100, DNG). I think, this is about the maximum you can get out of this sort of picture, taken within these quite challenging conditions (and with the aforementioned drone). Yes, it's not D810 quality, but I don't have the means to fly up such a big body
and at least, the picture has the merit to exist...
