In Karlovac, a city on four rivers in my beautiful Croatia, there is a beautiful and modern hotel with a large aquarium full of colorful and beautiful fish. Just before the hotel closed, they allowed me to take pictures of them.
So, let's go see together!
I took the photos with a Nikon D750, 50mm lens, f/1.8, manual mode, RAW format required, variable ISO and shutter speed. Processing in Photoshop - Camera Raw Filter.
