Sunflower with Red Halo

A sunflower head (Helianthus annuus) faces the camera on its stem in a garden bed. Bright yellow petals are brushed with rusty red toward a dense, dark-brown seed disk; soft, even daylight and a shallow depth of field keep the bloom sharp while the leaves blur behind it. You can see the tight spiral of central florets and a ring of dark anthers around the disk.
