Icy River. I was teaching my Masterclass in the Swiss Alps in october 2021 and it was very cold, high up he mountains for this time of year. The river was partly frozen and therefor I decided to go in the river to make this shot. I used a NiSi S6 filterholder, a NiSi Medium Nano IR GND8 3 stops gradual filter, a NiSi Landscape polarizer and a NiSi IRND64 6 stops ND filter on a Leofoto Summit LM 324-CL tripod with my Sigma 14mm f/1.8 DG HSM Art lens.
