Wow amazing place and beautiful shots!
I should come in turkey someday.
It's not your GH4, isn'it?
We have a similar place South of Rome unfortunately without so many fishes. It's a karst lake who flows in a river:
Trouts reproduce in this part of the year and we dive down the river trough a ripping current. We leave one car 3 KM downstream and we get carried away with the camera in our hands.
I have a lot of shots never published. You are making me want to edit something.
Some years ago I just published a teaser and nothing more... time time time...
