Sunset on Na Pali Coast, Kauai

You can't tell from this picture, but it was shot in the rain. The light rain came on suddenly - just as the sunset was reaching peak color. I was not too concerned about my gear as both the camera and lens were sealed against such rain, but keeping the front element dry (for optical reasons) was a bit of a challenge. Always keep a microfiber cloth handy.
 
Rain comes from clouds and clouds are needed for dramatic sunsets. In this case, I'll take the rain.
 
I was shooting with two cameras at this time. I was capturing (handheld) waves hitting the cliffs with a telephoto zoom (70-300 L) and was capturing the sunset with a normal zoom on a tripod. This image is an HDR that utilized three exposures to get a little detail in the shaded rock and cliffs.
