G I know you like this picture
You got very big overexposed spot in the middle
I don't think you can fix this easily
I will recommend to Clone the dead spot, replace the sky or trash the picture
did not sound that good but i thing you just waisting your time try to fix something it will not work
I don't know if you re close to this beautiful place
That's my opinion
Thanks Emmanuel
But if i was you i will try to take the picture again
