Suggestions for a nubie in 3D?

I want to make tiny seeds I have photographed with the Canon MP-65 and 5DIII, from 2 to 3 D.  Is that possible, starting with an existing RAW or

Seed pod with tiny seeds visible as dark "buggers" inside

Velvet Leaf with pods and small yellow flowers

TIFF file?

The seeds are, for example, the common foxtail, giant foxtail, Velvet leaf, Pigweed.

What software would you suggest I look at?

The final product will be a black and white for a book being finished up on Weeds and Seeds, by a Horticultural Prof at a state university.

I've gotten great stuff, but he now wants to have the photography on the first page of each chapter, to be --what I would call--3D os one tiny seed.

I've looked at the equipment that Robert LLewellyn uses  for his book on Seeing Trees.  terrific work--where the camera moves around the tree leaf or seed pod, on top of a 5' light table.  That kind of equipment an run up to $1500 or more.

The simplest and fastest solution is to re-photograph all the subjects in 3D.

Re: Suggestions for a nubie in 3D?

I agree.  "Conversion" to 3D can take so much effort, it's MUCH easier to take two shots and use StereoPhotoMaker to edit them.

The distance between shots can be calculated by the simple 1/30th rule (shift 1/30th the distane to your closest detail), which will be quite small for macro shots...

Don'r move or alter lighting between shots.

1/30 rule is not absolute  for macro. When you examine an interesting object at close distances for sure this rule can even be 1/5, and that will be very natural.  I have done that many times.

For his samples, I would go with 1:20 for larger subjects and 1:15 to 1:10 for smaller subjects.

Re: Suggestions for a nubie in 3D?

You are correct, of course.  I should have said that the1/30th rule is a starting point.  It mostly applies to scenes that include both close an very distant elements.

I like to "bracket" my interaxial movements.

Another benefit of true stereo pair shots is depth realism within all the details.

Re: Suggestions for a nubie in 3D?

You write " what I would call--3D " Pardon me if I misread.

I do not think you are talking about stereoscopic pairs. Which is what stereoscopic 3-D usually conveys.. i looked at the sample of photographer you mentioned and I see nothing that would show parallax as in multiple image from different viewpoints presented for fusion by viewing.

I was going to go on with ideas about macro work in sliding bars and then stopped because I doubt this will be the nature of the book image you seek. Help us clear up. Can you link to a page that shows exactly what you are seeking the result to look like? I think i get it and it is not stereoscopic 3-D as we define it here.. 3-D now has multiple definitons in graphics...

Checking out Llewellyn web site. He gets super duper depth of field with focus stacking on a single image.  Which necessarily is done in the taking process by multiple combined exposures.  ( Not my thing but it must be not so hard with built in camera chips that do this..)

So no, that deep deep structural purity of a leaf or seed is not what we 3-D stereo nuts are all about...another forum thoug in this DPR site would  i guarantee  yield better results on high DOF with super macro objects.  And ideas on accessory  gear  and maybe software also for same.. Good luck my friend.

Aloha. Gerry

As a remark,"super duper depth of field with focus stacking" for stereoscopic 3D macro images  offers a spectacular effect!

I've always speculated that that would be the case.  But can you point to any examples where both 3D macro and focus stacking have been done?  I've yet to see one myself.

I've made myself a lot of them. I will open a new thread with some examples.:-)

Here is a cross-view 3d image which was produced by stacking lots of macro photos and letting the software create the 3d image.

Nicely done, Brian. What was the taking photo instrument/camera and lens- or dissecting microscope maybe- to get that hyper close up?.  It is a wow shot I admire.

Looks like a challenging project for anyone to undertake.  What is the secret if we may ask and learn as well as admire?

Re: Suggestions for a nubie in 3D?

Congrats! You have done a lot of impressive 3D macros!
I suppose Bill Costa (and others) will be amazed.

So, I will post only one more sample (cross-viewing), with the mention that my "specimen" is alive.

Re: Suggestions for a nubie in 3D?

Where's Natural Mysteries, and what does he/she really want?

I have had great success with my Fuji W3 to make sharp-depth closeups without need for stacking. Under good lighting, the depth-of-field is great. This is an African flower that I adjusted sharpness and color in editing and the spacing in Stereomaker. I like to have flowers jump out of the 3D window. This flower was over 1.5 feet high and you can still see good sharpness by the ground.

Re: Suggestions for a nubie in 3D?

We have discussed about stacking in macro pictures.
On the left side of the flower there is a small insect. If you take a photo of just that insect, then we can discuss about DOF in the macro photography. And not even to talk about photographying just the head of this insect (like in some amazing photos demonstrated by Brian).

Otherwise, your photo is very nice!

The photo I gave a link to on Flickr is not taken by me. It is taken by someone I follow on Flickr.

Here is a photo taken by me in 2014. It is not a stacked photo, just a single photo for right and single photo for left. I think I did it cha-cha style, with a macro lens set-up.

The value of the examples remains the same, no matter who made them.

Re: Suggestions for a nubie in 3D?

While that photo does "work", the deviation is too excessive for a realistic view, mainly due to the large interaxial on the Fuji on such close subject matter.

Not long ago, Panasonic made and sold a single mount lens with two close optical elements that could fit the standard mount on a Lumix camera. Limited in functionality... Dr T sold a modification which permitted a closer focus.... And I am led to believe it worked reasonably well. Stereo macro is a great thing to play with....

And with still objects, there is no real problem except getting a good single lens camera and a focus rail and a still subject.. I have tried a fiew efforts kind of free hand without computation. And way way back there was the expensive Macro Stereo Realist a prize to find anywhere..

VW model about 8 " long  SBS

Realist with a single camera two exposures w a point and shoot option for same C 5050  SBS

Our mystery nubie has moved on...to the larger world or to watch TV. Whatever. I think he misled by stopping here, so Aloooha Mystery Person..gs
