These mountains often referred to as Bali Hai. It refers to a song written by Richard Rodgers and Oscar Hammerstein II from the musical South Pacific. This area resembles the island of Tioman, which is the original Bali Hai.
With the sun rising behind the camera, openings in the clouds allowed the light to filter into the clouds and illuminate the mountains on the opposite side of Hanalei Bay. Within 10 minutes the rain came in and this low warm light was gone for the day, replaced later by the bright light of mid-day. I used a long exposure to show the motion in the clouds. Also, the long exposure time smoothed out the water and simplified the image. That enhanced the effect of light hitting the posts of the pier.
