After years of research on long exposure photography, Brazilina photographer Vitor Schietti was able to create his “Impermanent Sculptures” project by manual waving of fireworks, some post processing, and then by combining up to 12 shots into a single image.
In an interview with Colossal, Schietti said that the usage of ND filters was vital to find a perfect balance between the fading twilight and the brightness of the fireworks.
“Only a few attempts were allowed per day, since the time frame during which this balance is possible is very narrow (30 to 50 minutes),” he added.
