Not having been to a waterfall in over 4 months, I felt that was long enough. I knew the South Fork River in River Falls, Wisconsin was spring fed, so figured is would be flowing enough to capture. I had been to the falls exactly one year earlier and the scenery was quite different. This year there were no colorful flowers growing anywhere, just snow and ice. The falls were still quite beautiful and I had the place to myself. It took about 4.5 hours to capture 4500 images I needed to create the video. The lighting was perfectly even as it was a very cloudy and rainy day.
