This is photo of the outdoor swimming pool Vyzlovka in the Czech Republic.
Techniques of the world-famous icemanWim Hof can be practiced in it at the time of the photoshoot. The whole surface was frozen and in some places, there were ice floes.
High iso and the maximum lens aperture were used during the photo shoot, because the picture was taken without a tripod from the hand shortly after blue hour.
