This daisy-like flower is actually a dahlia. The rest of the plant is very dahlia-like but not the flower.
Got right on top of this flower with a 105 1:1 macro plus a 1.4X teleconverter (plus a circular polarizer which I *always* keep on my macro lens when working with flowers - they "glare").
Used selective focus to intentionally blur the petals in order make the "sunshine" stand out. The shallow depth of field adds a feeling of depth.
