This is a hoverfly on a daylily, with the flower itself providing the background. I changed the flower colour from yellow to cream to increase the contrast with the subject. It is actually produced from four images stacked to give better depth-of-field.
Canon 7Dii, Laowa 100mm lens, 1/6000sec, f6.7, ISO1600.
Magnolia blossom in infrared. The background is blue sky, which is rendered dark in infrared, and I used a polarising filter to darken it further.
