Blue dahlias with layered petals photographed with selective focus and dramatic lighting

Macro photograph using selective focus technique to isolate central dahlia bloom in sharp detail while background flowers render blurred. Cool-toned color cast dominates frame through blue and cyan hues with warm peachy highlights creating contrast across layered petals. Complex petal structure exhibits radial symmetry with precise arrangement creating geometric patterns. Lighting appears directional, creating dimensional shadows within flower centers and across overlapping petals. Shallow depth of field emphasizes foreground subject against densely populated floral arrangement.
