At first glance I thought it was a worked photo! The blue is so intense that it looks like a lie. I, who live near the sea, never tire of admiring it and even of fearing it. Knowing the world hidden in the marine waters must be a wonderful but also overwhelming experience. Thank you for letting me know, through your images, things and spaces that I don't know. Greetings to you and hopefully you can dive again, @velimir!
