This photograph was taken on an overcast day with a Nikon D600 and a Nikkor 18-35 mm lens at 22 mm in Alberta, Canada. The exposure was f/8 and 1/320 sec (ISO 400), which allowed some of the turbulence in the falling water to be captured. The tonal and color balance, contrast, sharpness, etc. were adjusted using Topaz and Nik plug-ins in Photoshop CS5. Photograph by Irwin H. Segel, Davis, California.
