This is macro at its best! You’re looking at bars of steel, with all their different variations in texture and color. Amazing how a subject so monochromatic in nature can appear so colorful and varied. The slight offsets in stacking add to increased shadows, which are played up nicely by the contrast setting. The bright silver bars pop out at the viewer, their ridges shimmering in the light. It is pure heavy metal glam.
