My first Focus Stacked Macro Image

While I am trying to make the automation to do the focus stacking, it is also important to try out the stacking manually.  Today I did my first ever macro focus stacked image of a flower.

Setup: three extension tubes (36mm + 20mm + 12mm = 68mm) and reversed 50mm lens.  This gives a 2:1 macro (double size) image.  Here is the setup and the result.  Its a stack of 10 images done in photoshop.
