The "subtle pinks" required a better camera profile in LR than the standard Adobe one. I did not change anything else.
Aperture was f/4, not f/2. What the photo does not reveal is that the inflorescence is rather small, and had to be shot near minimum focusing distance with the close-up lens on. In that case, f/2 will get nearly everything blurry. The purpose however was to "simulate" a flower bouquet, requiring sharpness on at least a few summits. By experience, f/4 offers a good balance between "confused" backgrounds and sharp subjects on close-ups (around 1:5 reproduction ratio).
