An abstraction of some of the many photogenic corners of the Rio Tinto, with a cutout of a waterfall whose fall creates a swirl of foam. I have tried to photograph the scene with a moderate speed, for, on the one hand, emphasize the twisting motion of foam and on the other hand, to keep texture at the same time in the scene. When we find a composition with water in movement that we like, it turns out to be very interesting to try to photograph it with different speeds, to acheive the photo that contains the appropriate exposure time according to our criteria. A neutral grey filter (variable) turns out to be of great help in this process.
Photo taken with digital camera, 80-400mm F:4 lens at 180 mm, at F:16, 100 ISO, 1 second, polarizing filter, variable grey filter tripod.
