Thanks for commenting! I've never thought of scales in 3D. The depth looks exaggerated, perhaps illusory or just lack of familiarity. Are we seeing the stems of the missing scales protruding from the substrate? Yes, stems from missing scales. When it comes to synthetic stereo the depth is not perfec...

Thanks for the comments! Love the lighting on those first two shots, very special. The first two pictures are part of a stack and stich. I did not want the light to change between the pictures, so I used cross polarized epi light. This type of light is practically shadow less. I stacked it with Zere...

No success with 3D from Zerene Stacker Stereo/Rocking

I have a couple of times tried to do 3D models with Zerene Stackers Stereo/Rocking function. I must say that I have not found a way to make it work. Here is one example of pictures I used. 8 pictures of a trilobite created with conical path. http://www.photomacrography.net/forum/userpix/3238_Trilobi...

Very interesting, thanks for posting. I have very little experience with 3D printing. What material do you recommend if I want to print a reliable part for this type of use?

Thanks for the comment I personally wouldn't even consider using either the finite or infinity type 20x 0.75 objectives without a coverslip. That depends on what you want to photograph and finding a way to do it with the gear you have. For me it started with curiosity and this post 2015 https://www....

Hi Adalbert I have been thinking about this lens. Thanks for testing it. Have you tried to see the difference in image quality with different distances between the tube lens and the sensor? If you have, it would be nice to se the results. I have posted my testing with the Nikon Plan apo 20x NA 0.75 ...

In the end I recovered my Helicon license. The soft looks much better 10 years later, although as I thought the resolution is not enough for the 3D I need. Actually on a surface of fairly smooth curves covered by a skin that contains the image and gives it that detailed look. But if the surface is ...

I have spent much of the day trying to understand the creation of a 3D volume in Photoshop ... without luck. I manage to texture the basic shapes by default (cylinder, sphere ... bottle, what were the Photoshop programmers thinking?:roll:) I also get your "hedge hog" ... but I can't apply my depth ...

This is a spectacular species of Morpho. Nice photo, but the blue scales look a bit speckly, as if the light was partly coherent. Might need a milk diffuser to decohere the light and eliminate the speckle pattern. Hi Lou Jost Thanks for the nice comments and the interesting suggestions. The scales ...

wow! how much information! I believe that with a synthetic 3D, created from the deep displacement of the images of a stack, it will give me enough information for what I need. I have also tested rotating objects and many photos from all angles (an old music disc player is a good platform to start) ...
