Yeah, you're probably right, Slobodan. Here's the color version. I cropped! (I'm so ashamed.) I had the camera on a tripod shooting up the stream at ISO 100, mirror up, and f/16. Shutter speed was around 1/4 sec. These two guys came down to drink. I didn't have time to change anything on the camera. Just time to swing it around, zoom, focus, and hit the cable release -- twice. Then they were gone.
