Rosenthal piled stones and a sandbag so he had something on which to stand, as he was only 5 feet and 5 inches (1.65 m) tall. He set his camera for a lens setting between f/8 and f/11 and the shutter speed at 1/400th second. Then, out of the corner of his eye, he saw six Marines start to raise the second flag. He swung his camera around toward the action and pushed the shutter. Three feet to his right, Sgt. Genaust captured the flag-raising from nearly the same angle using color motion picture film. To make sure he had a worthwhile photo to send to the AP, Rosenthal took another black and white photograph showing four of the second flag-raisers steadying the flagstaff waiting for the bottom of the pipe to be more secured with rocks; and afterwards a rope. When that was done, Rosenthal gathered a group of sixteen Marines and two Navy corpsmen around the base of the flagstaff for a posed shot (called the Gung Ho photo) which included First Lieutenant Harold Schrier, the only officer on the summit, who had volunteered to take the 40-man patrol up Mount Suribachi that morning to seize and occupy the crest and raise the battalion's flag.
