Two completely unrelated shots .
That first looks like a double-exposure or a composite, but I believe it is just a reflection? That second shot of the gears... very industrial, and one of the best you've done recently, IMO.
Good eye on the first one. It is a reflection on a pool, but added a layer for additional blur.
Glad you liked the second one.
Thanks for the comments.
Both are well thought out and artfully shot.
Nice work Cristóbal!
Thanks Gato, I ended reprocessing the second one, but this version still works.
