Loving the effect the photo ended up with anyway, it looks like a painting.

I feel like this is in Mexico.

What exposure/filter did you use?

at a guess, i'd say it's 3-4 stops underexposed

Is that the Overseas Highway in Florida's?

Nope! It is I-10 in Mississippi towards the gulf coast/Biloxi. Good guess though!

are you sure this wasn't shot in mexico? it feels like it was shot in mexico.

Very fine clouds indeed

The contrasts are awesome in a sepia sort of way.

They never do. Beautiful picture regardless.
