Having photographed this location many times, the water flow was low enough to get right into the middle of the stream looking up at the surrounding trees. But the only location suitable was a little splashy, and so I only managed to get one usable image before the front of my camera got soaked. Wet feet from standing in a lower level rockpool I could handle okay, but the camera was quite wet. The 5 second exposure was just long enough to expose the scene and short enough to avoid too many splashes.
I wouldn't ask you to do this on a workshop but it really is fun, and that makes three ways my camera has been soaked in the past twelve months, waves on the coast, the little stream seen here and torrential rain in Antrim that saw water getting into the circuitry and misting up the LCD information panel. The camera still worked but didn't display anything at all. A good drying out near a radiator but not too warm, and with some silica gel nearby soon sorts that out. Still not the best way to care for your camera!
