I have been playing with my new ring flash today.
This head of orchids is about 10cm front to back and the mid-point to camera distance is 45cm.
With the a 100 macro lens at F13, calculation gives a DOF of 1.2cm and yet......
The whole spray is in decent focus - a good demonstration of the possibilities of focus stacking.
No good for anything that moves of course, since you need to take multiple shots (12 in this case) at different focus points.
