Half Dome reflected off the Merced River.
There was a 3 stop difference between the top and bottom half but the difference of my GD and sunset filter combined was only 2 stops so I used multiple exposure to balance out the image where the filter was inverted for 1 shot. I was a bit sloppy in holding the filters and the very left edge of the image was not covered by the filters so I color burned it in PS to balance out the picture.
