The video was made in a small river not far from Sofia.
By the end of summer it is almost dry.
The camera I was shooting was small in size and I had sunk it all over.
So at least I had good light and the opportunity to see the rocks well at the bottom.
It is beautiful! Even the waves that are formed can be seen.
This river, named Old River, springs from the Sredna Gora Mountain.
It is not large, it is not deep water, but there are hills near it, with pastures and forests.
