Taken In Snowdonia North Wales. Opposit Llyn Ogwen. This small waterfall struggled to keep flowing. The temperature was about -5 and the water had started to freeze. I used my Eos 40D with a 100-300mm Lens. With a bracket of 1 stop either side of my main exposure. 1/4 Sec. @f22, 1/6 Sec. @ f22 and 1/2 Sec. @ f22. Processed in Raw and opened in Photoshop.
The exposiures were combined together in Photoshop layers to bring out the detail in both highlights and shadows and detail in the moving water.
