I wanted more than just another picture of gilded church domes. I wanted a photograph rich in energy, particularly tension. I chose a camera position allowing me to shoot one dome emerging from another. I noticed a thin span of blue sky running between the big dome at center and the smaller steeple on the left. That small area creates tension, and I increased it by zooming in to apply pressure on all four sides of the picture at once. The gilded tiles glitter in the morning sun. The decorative sunburst coming out of the steeple is an appropriate touch for this sunsplashed picture. But the key element is the pressure I applied to those structures from the edges -- it makes the entire image crackle with energy and tension.
