Had some fun experimenting here with the light. The image has two suns. The primary sun is set at a 300 heading with a -1 elevation which is below the horizon. At this point, the foreground is too dark so I added a second sun which also is set at a 300 heading; but, with Light atmosphere unchecked, elevation set at 12, Strength set at 5.5, Cast shadows, Do soft shadows, Glow in atmosphere unchecked; and, Visible disc unchecked. This set up appeared to yield a reasonably well lighted foreground notwithstanding a negative altitude setting which makes for a very nice atmosphere for a sunset or rise.
Additionally, I added one of Oshyan's Fill lights set 180 degrees from the main suns at a 10 degree elevation and strength at 0.13125 - Cast shadows unchecked.
