Waterfalls of spearfsih canyon. scheduled for 7:30 - 10:30pm. Come with me to explore the three main waterfalls found in Spearfish Canyon: Roughlock, Spearfish, and Bridal Veil falls. Waterfalls have been my favorite subjects for years now, no matter the water level. We'll talk about technical concepts and tools, including camera settings and filters, and explore each location for possible compositions. While a tripod, ND, and polarizing, filters are optional, having them will allow you to slow the shutter speed, remove glare, and blur the water in your images. with tomas alvarez.
