Did you know the difference between human visual perception and the way photographs represents reality.

To make photographs that communicate your ideas, you will also have to learn the differences between human visual perception and the way photographs represents reality.

When viewers look at a photograph the eye travels over the image, seeing only a small part at a time. Some visual elements attract and guide the eye more than others. The eye tends to follow the path of a line. Converging lines especially seem to draw the eye to the point of convergence. The eye is drawn to areas of tone different from the average. In most photographs the lightest areas draw attention, but in high key image – one with mostly light tones – a dark area may initially attract the eye. If two elements are otherwise identical the eye will generally be drawn to the one larger in size. All other things being equal, visual elements at the center of the frame are given more importance. The eye can also be drawn by certain subject matter, such as human presence in a photograph, particularly the eyes of those portrayed. This is especially true when the eyes of a subject are looking directly into the camera, and therefore directly into the viewer’s eye. Any subject matter that carries a strong emotional message, such as a shocking or extremely unusual event, will also attract eye.

The hand of a Japanese soldier killed by a bomb blast is seen in the rubble which covered the island. Note the fly on his finger. One of the most controversial elements of the Iwo Jima invasion was the extent of the pre-landing bombardment. Preliminary air bombardment of Iwo Jima was delivered by heavy bombers operating from the Marianas bases. B-24 Liberators bombed for 70 consecutive days, releasing at 18000-20000 feet (5500-6100 meters) usually against antiaircraft fire. Once or twice a group of B-29 Superfortresses assisted. The prolonged aerial bombardment of Iwo Jima had no effect in the reduction of well prepared and heavily fortified defensive installations. The Japanese estimated that 40 percent of the bombs missed the island completely. Direct air support operations against Iwo Jima began on D-3 (February 16, 1945) with the arrival of Task Forces 52, consisting of nine to eleven escort carriers. Marine commanders had requested ten days of preliminary shelling. 5th Fleet commander US Navy Admiral RaySubject Matter. Edward Steichen, Iwo Jima:- Although this image is fairly uniform in tone and texture, the eye is strongly drawn to the fingers of the buried soldier because of the shocking nature of the situation.
