If you are tired of the usual long exposure photos, then this post is for you. Japanese photographer Yume Cyan has spent the last month in the forests of Nagoya City, Japan, shooting some surreal long exposure photographs of fireflies.
His long exposure shots (often 30 seconds at ISO 800) were taken with a Canon 5D Mark III and 50 mm lens. The aperture was set at f/2.8 – this made the closer fireflies look like out-of-focus circles of light. Finally the photos were combined together into composite shots.
According to Wikipedia, there are more than 2,000 species of fireflies, but despite their name, only some species produce adults that glow. These lightning bugs produce the most efficient light in the world – nearly 100 percent of the energy in the chemical reaction is emitted as light.
You can usually take such surreal photographs during the rainy seasons, from June to July, when fireflies mate after thunderstorms. For more examples, be sure to check out Long Exposure Photos of Gold Fireflies by Yuki Karo.
