One of my favorite techniques to demonstrate on a workshop is the technique of “shooting through.” It’s really very simple. You need a large group of flowers and with a long focal length or macro lens, position flowers very close to your lens. The petals can actually touch your lens. Then, focus on a flower beyond the close petals and capture the shot with a wide aperture. While demonstrating for the group, I captured this image of golden lupine with a 100mm lens, f/4, 1/250 sec.
