When I go searching for cascades and waterfalls to photograph, I get especially excited to find some that are a combination of flows from a few directions. Often, because the water is tumbling over a variety of rocks, the textures are different making for a pleasing composition.
One of the advantages of shooting woodland water features in the early morning are the slow shutter speeds which make the use of neutral density filters unnecessary to get a nice soft look. On the other hand, one of the difficulties in shooting woodland water features in the early morning are the slow shutter speeds which make the use of higher ISO values to provide faster exposures needed to retain some detail in the flowing water, especially where it splashes at the bottom. It really takes a bit of experimentation to find the right combination as the flows vary as well as the light.
