This orchid is setting out its second set of flowers since it was presented to my wife as a gift some months ago.
I shot this with my 100 mm macro lens at f/4.0.
Camera to flower distance was 30o mm. At f/4.0, the depth of field is so small that only a small part of the flower is in focus.
Using a macro rail, I stepped the camera about 2 mm per exposure to get this shot, stacking 28 images and letting Photoshop churn away on it for several hours for this result.
