What is 'focus stacking', Pete? Love the colour of the orchid. Focus stacking is similar to exposure stacking / merge (HDR); the difference is one uses different focus points rather than exposure values.
I used a set of Hoya macro filters which enables closer focus plane. Since my camera was extremely close to the bloom I used the widest aperture available (f 2.8) which provided a decent exposure, but had an extremely narrow DOF. I used a single point focus point on my camera and changed it's location for successive captures. I imported all the captures into PSE 18 then used Elements+ focus stacking script to produce an image with a much larger DOF than any single image.
I've written a tutorial which is posted on CloudUp - practice images included.
Using macro filters approximates true macro photography without the huge expense.

You can use focus stacking for any scene where you want the image to be tack sharp from front to back.
For example, you might have a landscape scene with a rock or other feature very close to the camera as the subject and hills or whatever far away in the distant background and you want the rock and background all to be sharp.
The method I use is to set up my camera on a tripod and then take multiple shots using the various focus points on my camera for each shot to focus on the rock and points at various distances in the background. I then merge the images manually in PSE or use Elements+.

Pete, thanks for taking the time to write this tutorial and to share it with our members! Your generosity is truly appreciated.

Thank you Pete.
I know even less about manual photography, than I do, Elements.
