Oscar - excellent work!! it's almost getting to the point where I'll feel comfortable buying a specimen without holding it in my hands. seems all that is left is to be able to size the piece on my computer screen such that it's presented at actual size. (this can probably be done but I'm not smart enough to do it.)
please let me make sure I understand the technical terminology:
- the final result is a series of 5 "frames"
- each "frame" is a compression of 26 photos taken at different focus points (to enhance the depth of field)
- the focus point of each of the 26 photos was changed 0.0416667 mm
- each "frame" was taken with the specimen rotated(?) (this is where I'm not clear) "1.08333 mm" (you use the term "displacement" - do you mean angular displacement - if so it may be easier to state it in degrees??)
thanks for the excellent work and also thanks for communicating in English.

Sorry i don't explain very well... In this 3D/360º animation two devices involved; one 3D/360º table with high resolution degrees with minimal rotate of 0.0375º per movement and one MacroRail to make stacking images. In this case with minimal of 1.6 microns. See the photo that i attached.
With the program move the MacroRail to the first position (INI position) of sequence of photos. To complete one stack i need 26 photos separated between 0.0416667 mm, in total from INI pos to END pos the MacroRail displacement the camera 1.08333 mm. When done with the sequence, the software call in this case to Helicon Focus method C and generate one stacking image. This is the first frame of animation.
Next the software move the 3D/360º table 12 movements = 0,45º, move the MacroRail to the INI pos and repeat the same process in total of 5 times.
When done, we have 5 frames or stacked photos. Now the software generate the adobe flash animation (can generate html5 if i liked) and publish this.
The result is that you see. Is very preliminary test version, but it's very close to what I'm looking for. In the next few weeks I will improve the results.
I hope explain better.
You can see 3d/360º high resolution prototype and one MacroRail horizontal setup with camera in reverse orientation
Software that i development to control both devices, rotate and macrophotography
To compare, this is the normal use of MacroRail in vertical setup and the camera go to down when take photos

CNC meets digital optics meets software meets art for arts sake. Beautiful. We are reaching new standards for photo perfection and info density. Fantastic Oscar, nice, very nice. I'm sure someone, somewhere, right now is using a 3D printer to bring these things to hand. If not, why not? The possibilities seem boundless.

I am the happy owner of one of those MacroRail machines and I am trying to convince Oscar to bring at least one to the next Münich Show. Münich is THE place to show everybody how this works. Perhaps some of you could be more persuasive.... :-)
PS: In Münich I had to wait several minutes behind a man who was taking pictures to one of the golds... about 20 pictures per piece!!
