Recently I posted a similar photo of the Prague Castle and the Charles Bridge. I felt like trying the similar composition in black and white. I played with it a bit and I quite like what I came up with. This is black and white HDR picture. How did I create it? Very simple. After all the blending and usual HDR stuff I converted it to black and white. I think this adds details to some areas which otherwise would be lost. Anyway, technique does not matter that much, it is important for me that I like the result:).
