I had a bit of a problem trying to do the lathe. I needed a 28mm lens to get it in, and due to the inherently wide dof manually focussing accurately along various points that I could later identify for this post was a nightmare. So an alternative subject had to be found where I could mentally note the focus points between frames, hence this choice of currently completed workshop projects. Repaired ballhead, rotating base and stub centre column on Manfrotto 055 tripod.
Manual refocussing of the lens between frames was chosen as opposed to my Micro plate. This was to confirm that it could be done for the benefit of those without such a plate. Aperture was kept to a shallow f8, again to check the effect over a subject with a depth of 130mm. 9 focus points over 130mm of depth is probably the fewest I would currently recommend. Camera was set to jpeg medium fine again to replicate a fairly worse case scenario for those that do not use RAW. ( I can sense Foxy's thoughts from here.  )
Attatched images :
1) Image with explanitory notes
2) The first frame at focus point 1 to show dof at f8
3) The final stacked image

Don, Again an excellent example of focus stacking, but just one point, especially when using a focus rail (screw/worm drive) you only need to establish your first point of focus, then depending on the thread size just give it 1-2 revolutions to obtain the varying focus points.
not quite so simple when you're out in the field hand holding the camera.
