This turned out to be a labor of love to get the image as I wanted it. Initially, the comp was good, but awfully busy. I wanted the BG more blurred and hazy with the three gallardia in focus blossoms and some of the close stems sharp and bright.
First, I separated the blossoms on a top layer, sharpened and saturated them. Using the level tool, I darkened the lower layer and darkened it further in the midtones another 8 or 9%. Then I put a 0.5 ND from the bottom to the top. Finally I put a tilt-shift blur from the bottom to the top.
After the darkening and the blur, I came back with a history brush and painted over the blurred stems and a few of the expired blossoms to bring them back to their focus before the tilt-shift blur. Then I bordered it, signed it and flattened it.
