Yesterday morning I woke to minus 17 degree Celsius (about 1 degree Fahrenheit). With the wind chill, it was well into the minus 20s. Our camera club had been planning an outing to Warsaw Caves Conservation Area just north of Lakefield, Ontario for several months now, and I had been looking forward to visiting the area for a while. We were outside for just over two hours and after about 80 photos, my camera battery decided to call it a day. Note to self: add ‘extra batteries’ to camera wish list. Warsaw Caves is an interesting place to visit in the winter particularly due to the heat rising from the caves cause massive amounts of ice to form on overhanging trees. This was also my first attempt at using my new polarizing filter, but forgot to rotate it for a darkened sky. It did allow me to try and capture a ‘silky’ water effect to some extent. While not a ND filter, I still think it worked quite well.
