Nice macro. You mean its focus stacked, - right?

@Willie - The menu item in the camera is called focus shift. But yeah you do the focus stacking in PS.

As a technical exercise it's worked.

It's a technique I have yet to try. I have some observations which you, or anyone else, is free to comment on.
I was under the impression you don't need to use small apertures, something mid range is good as the software stitches together the sharp bits.Given there's not so much depth in the subject and you used 25 images could you have managed with less?

Technical exercise is one thing, aesthetics are another and are the same considerations you'd take into account for any still life, single shot or focus stacked.

Just a couple of ideas. There's not a lot of colour, so mono is an option. You used natural light, which is fine, but it would be worht experimenting with some supplementaty light. Easier with continuous light, for example a coloured LED torch(es) for an accent, as if catching the lights at a performance venue.

A diagonal composition would look leass static.

@dark Lord - This was an exercise in working out how to do this. As I was not aware what the optimum number of shots was to cover the range/distance from back to front I decided to over do it. f22 as the camera is on a tripod anyway and giving myself as much DoF as possible to ensure success.

As I said its a proof of concept type shot and yes I imagine in the future I will experiment with more open aperture and less shots but then again if it works then why change the formula Grin

Interesting image from a technical view point. Using a very small aperture of f22 would theoretically result in lens diffraction and less sharpness. Most lens are sharpest of f8 or f11 but we are getting into a nit picking area here.
Good one

That's what I wanted to know mark, something about the methodology and reasoning, not just for myself but anyone else who happens to read this.

I'll second Keith's thoughts - the next experiment could be with fewer images (how few is enough?) and optimum aperture (is the final result noticeably sharper?)
