Vary your depth of field (DOF = Zone of acceptable sharpness) to see what looks best. Get close to your flower and have a background that is distant from your flower with nice muted or complementary shades. This first cone-flower at f/9 (more wide open aperture) has a softer background than the one shot at f/22 with the same 105 mm macro lens (focal length). OR use a more telephoto lens zoomed in at 200 or 300 mm while able to be more distant from the flower. The key factors that influence DOF: aperture, focal length and distance to the subject.Coneflower at f/9Pink magenta purple cone-flowers with muted background in pastels.Coneflower at f/22
