Took this long ago with a 100-300 zoom with close focus in a marsh. The flowers themselves were in a spot of bright mid-day sunlight shining through the bush, while the background was in shade. So I underexposed quite a bit (I think at least -1.5 to -2.0 stops) and rendered the background entirely dark. Since the flowers were yellow and reflected so much light, it helped even more. So there was no photoshop work done to this, this was as it was actually shot.
This was taken in a dining room and I put a black background behind the flowers and again underexposed so this one was worked up a bit for that similar effect. These two remind me of flamenco dancers.
