Rio do Boi I

These series was made during a 7 hours trail with my son. This trail is called Rio do Boi (Bull's River) and goes inside the Itaimbezinho canyon, wich in tupi-guarani means sharp rock. I made these photographs in raw format an long exposure using a neutral density filter to lower the speed. I like the effect of time running in my photographs, it adds a 4th dimension. This is the kind of place you feel small beside a 2000 feet rock wall.
