Shot with Canon 18-55mm at 18mm, f/13, ISO400, for 2 mins using a stacked Rockfish Circular Polarizer, Hoya ND1000, and Hoya NDx10 Grad Filter. This is by far the best shot I have ever gotten with my Canon 600D, though I would not recommend stacking all three filters as this caused severe vignetting (my Rockfish CP is unfortunately cross-threaded onto my lens, so I had to make due). This is the jpeg version of the shot, but I also have it in RAW format.
