Pink cosmos flower with selective color and blurred background

Photography employing selective color technique with desaturated grayscale background and preserved pink petals. Cosmos flower displays delicate white-to-pink gradient petals arranged in radiating pattern around compact yellow-black central disk florets. Shallow depth of field creates bokeh blur on secondary blooms. Technical execution demonstrates controlled color isolation through masking methodology, precise focus positioning, and naturalistic petal texture rendering with visible striations and translucency characteristics.
