Edgerton and his assistant, Kim Vandiver, made a series of color Schlieren explorations of flames with bullets and fans in 1973. This particular image made the cover of "Scientific American" in 1973. Palm Press published this 24 x 18 inch (61 x 45.7 cm) dye transfer edition in 1989 from the original 35mm High Speed Ektachrome transparency. This is number 14 in an edition of 18 (+4 APs). About 6 remain and the majority now reside in museum collections.
