Blue hydrangea flowers display dense clustered petals in shallow focus.

Photographic capture employing macro depth-of-field technique on blue hydrangea blooms. Sharp focal plane isolates foreground clusters while background flowers render progressively blurred. Petal morphology exhibits characteristic four-lobed sepals with central stamens. Lighting source positioned overhead produces directional illumination across petal surfaces, generating distinct bright-to-shadow gradients. Color saturation concentrated in blue spectrum wavelengths throughout specimen. Floral arrangement displays natural clustering density typical of hydrangea inflorescence structure.
