Accomplished Color to B&W transition by using Desaturation, Violet B&W filter. Increased Contrast, Mid tone and Shadow level.
All elements of nature and black and White Photography are captured in this photo.
Originally a Color image, but was thinking Zone System, when I took it. Happy with attempt to honor Adams with all 10 zones in conversion to B&W with Picassa software. I think it has great clouds with dark sky feeding into magnificent rushing water.
