Ozone falls can be a challenging shoot. With bright water flowing over wet, black rock under a bright background yields a dynamic range issue for both the camera and for an appealing image. An HDR technique is the answer. This image is the result of two pictures blended together. The water and trees are from a shorter exposure than the dark rock.
A challenge also arises when shooting water with exposures long enough to create a motion blur. Any breeze present will create a similar blur in your leaves.
