@waterwingz I didn't have the additional focus stacking options running when I took the image in the above post (Winchester Cathedral BTW). Now I would select Mac2Inf option and the camera would do a full focus stack from the camera's minimum focus to the blur defined infinity, say at 3xHF distance, ie giving an infinity blur of CoC/3.
For the above, I focused on the nearest tile and the script also took three exposures at each focus plane. Aperture was f/6.3 at a focal length of 8.8mm.
The script took four focus brackets, thus giving 12 images for post processing in LR (for the exposures) and Helicon Focus for the processed exposures.
I had bookends switched on, which means each bracket set is easy to spot in LR.
BTW here is another example of a 3x4 stack, ie 3 exposures at 4 focus stations.
