ManuelVilardeMacedo: Nothing new about flash sync, aka stoboscopic photography. Harold Edgerton pioneered it in the 40's. Spectacular photos, though.
I had the pleasure to meet Dr. Edgerton once at a conference. He was tweaking a repeating strobe with bright green fluorescent streaming water to make it look still and I asked him how he came to learn all he had about strobes and e-flash. He told me the secret was to "fool around a lot." He was right.
