| STREET LIFE Istanbul, Turkey Martin Roemers By foot, rail, and automobile, people pass through Taksim Square, animating the modern hub of Istanbul. Schemes to restrict the area to foot traffic worry planners who fear the famous cross- roads could lose its creative energy. | TOGETHERNESS New York, New York Reinier Gerritsen Commuters kvetch about crowded trains, but New York's subway system helps account for a rela- tively low per capita energy use. For density and diversity---hallmarks of a vital city---look no further than rush hour on the line from Grand Cen- tral to Wall Street (right). Gerritsen's "Wall Street Stop" images are assem- bled from photos taken in rapid succession with different focal points. He combines the results on a computer so most faces appear equally sharp.
