We had done laboratory tests to see the impact of high-frame rates images on viewers. Viewers were shown identical films shot and projected at 24, 36, 48, 60, 66 and 72 fps, and all of them were monitored with electromyogram, electroencephalogram, galvanic skin response and electrocardiogram. The results were conclusive that the 60 fps profoundly increased the viewers’ visual stimulation. (via Douglas Trumbull Sees a Better Filmgoing Future - Creative COW)
