Here, the greens of the evergreen trees are muted while the blacks and whites of the rocks and snow whites along with the rust of the valley grass stands out.
The sun is obscured and an occasional patch of blue will show itself at the top of the falls. I have to move around to capture both the upper and lower falls in the shot as seen here. It is just a frame ,shoot at various speeds move and re frame and wait for the sun to add an extra layer of color. It is late January here in Yosemite National Park.
