Examples of Kenna work: http://www.michaelkenna.net/html/2008/france/index.html Astro guys take particular note of moonrise image. The extreme softness of the motion/time blur with perfect sharpness effect, whether exposed for only a few seconds or longer, is what I am referring to. I'd like to see examples of B/W, digital that achieves this. Not interested in doing technical images. As I have said it should be an as-taken image NOT a PS illustration. Some noise filtering and other routine PS adjustments are acceptable. I did a long exposure series years ago with low ISO film and ND filters that I'd like to try with digital cameras.
