Clam Shell Growth Rings on Lichen Bark

Concentric ridges etch the creamy surface of a clam shell, creating a tight spiral of textured layers. The shell rests on rough bark heavily speckled with patches of pale green and grey lichen. Soft, diffuse light from an overcast late morning fills the frame, eliminating harsh shadows and revealing the subtle undulations of the shell's ridges. Tiny droplets of condensation cling to a nearby glass surface, catching the light in sharp, clear beads. The scene shows the tactile contrast between the smooth, calcified shell and the organic, uneven texture of the lichen-covered wood. A fine line of white shell material catches the light at the very edge of the spiral.
