The tufas at Mono Lake in California is an iconic photographic venue and on the bucket list of every serious landscape photographer. In a recent trip to Mono Lake area I visited the tufas in the morning, afternoon, and evening. On one of the occasions there was a beautiful effulgent sunset, during which time I took many photos. The current photo was taken after the sun had set and the majority of photographers had left the site. I guess that they thought the show was over. I persisted and decided to explore the more mysterious colors that appear during the twilight. To get this photo I had a 2.5 second exposure that enabled me to bring out the subtle variations of twilight color.
