That's about it, and a sore buttocks...I sat there for an hour with my eye stuck to the viewfinder, doing my best to click whenever I saw one jump. So I snapped well over 300 shots, most of which were either out of focus or had a tail in it or just a head etc... Some of them were just really crisp freeze-frame pictures of running water, lol. . Another trick, if you have a dslr (probably works with upper end point and shoot cameras too), is to press the shutter button halfway and keep it pressed, while you wait for the next fish to make its move. That way, the camera is already focused when the fish passes through the sight & it doesn't waste any extra time before engaging the shutter.
Thanks for the kind words everyone .
