Green Flash and Atmospheric Optics
From July to December in 2022, I tried very hard to capture the green flash of the sun as it went down. Whenever the weather is sunny, I start paying attention to weather satellite cloud chart. It's a pity that the most common encounter at the beach is that the sun falls into the clouds in the last few minutes, so the green flash cannot be formed. But in the process of nearly twenty failures, the sun and clouds often have amazing performances, which always make people "wow!" It's so beautiful! "
In addition to green flashes and rare blue and purple flashes, this composite photo captures several beautiful sights as the sun sets. The second photo on the right is the green rim taken on December 24th. Generally, the green rim are very thin and difficult to see clearly. This green rim of the setting sun above the treetops in the distance is very clear!
