The cypress knees are curious structures that are part of the root system. This version started with the color picture below, made from three half-stop brackets processed in Nik HDR Efex, then applied a "Color Isolate Red" develop preset in Lightroom 3. The knees got lost is the straight monochrome conversion.
This HDR color version captures fairly well the minor chord dusk light and mood of the swamp.
In Nik Silver Efex Pro, I was able to get good separation between the knees and water without loosing detail using a split tone preset I made for landscapes.
