It might look OK but on closer inspection the edges of the petals (especially noticeable on the inner most petals) had a ghost image...
I had the camera on a tripod, shooting with a cable, mirror up, indoors, no movement. The exposure was 2 seconds using flash plus two continuous lights on the background.
The 2 second exposure was to get the background ambient-light closer to white, the flash should make the subject exposure about 1/700 sec. If I shot at 1/160 the ghost went away.
It had me foxed for a while, head scratching, trying to figure out where the ghost came from.
Solution: I am using a tripod and I had forgotten to turn off the lens Image Stabiliser. I have read that IS can generate image movement when the camera is on a tripod; I would usually switch it off but often forgot and had never noticed it before.
I find it interesting that the ghost was only noticeable when I had a long exposure, perhaps that was why I had not seen it before.
