Sunflowers, with their large size and bright colors, make great photo subjects. Add a bee to take the overall composition one step further.
For this image, I moved in close to the foreground flower, keeping it completely in the frame which places the center about 1/3 into the frame. I then moved to position a similar flower in the background. Again, that flower is fully contained in the frame and the green leaves anchor the bottom of the composition.
The shallow depth of field created by the combination of an 85mm focal length and f/1.4 aperture draws a viewer's eye directly to the bee and to the sharp flower petals (with strong contrast also pulling the viewer's eye to this location).
This image is razor sharp across the back of the bee (thanks to the Zeiss Otus 85), but details quickly soften in front of and behind that plane of sharp focus.
