Photogrammetry
Has anybody done any photogrammetry of insects? I am trying to produce a close to 3D image of an insect with a Stackshot rail and Cognisys turntable. I'll use Agisoft Metashape software to produce the 3D image.

3D object creation
Anybody here doing 3D object creation? The easiest way I have found so far is to use Object 2VR software which creates movies. What I want to do is create an image that you can move around at will to see different angles. I use the Cognisys system with a a rotating turntable so I get front to back i...

vertical vs. horizontal setup
What have photographers here found to be the advantages and disadvantages of a vertical camera setup vs. a horizontal setup? Right now I have a horizontal setup, that is with the camera/rail system on a horizontal plane. I like this setup because I can move my camera back and forth to accommodate la...

Dorsal view
I do like though the small background for the leveling head. I did make one of those out of 3/8" plywood. I put black plasticene clay on the back and then covered that with black velvet. Pinned insects stay perfectly still in the clay on the horizontal axis I need. Another solution to tilting in sev...

dorsal view
Again thanks to everyone who has given me suggestions as to how to take macro photos of a subject on a horizontal plane with the camera. I am also using tips from Sam Droege, who works for USGS. He has a very simple setup. He uses a jackstand with black clay and shoots the insects from a lateral poi...

posing insects
Thanks to all who have contributed advice and suggestions as to how to solve the problem of arranging pinned insects. What I came up with so far, is to photograph my subjects horizontally, pose the pinned insect on top of a small jackstand, which can be raised and lowered for height and stick the pi...

Small clip on system
Where did you get the small plastic alligator clip that would hold a subject in front of the lens? And does it have a pre-drilled hole in the end of the clip to attach to the articulated arm?

Helicon FB tube
I recently purchased a new device form Helicon Focus. I haven't received the device yet, but I'm eagerly awaiting the delivery. The device is called the Helicon FB tube. It is similar to an extension tube in form in that it fits in between the lens and the camera body. A cord connects with the camer...

Cognisys
Is anyone using the Cognisys stacking system? I bought the 3X StackShot system for stacking photography. It works very well for macro stacking solutions. Couple that system with Helicon focus remote and you have one heck of a system. The Helicon remote allows you to control all of the functions of t...

I need someway to photograph an insects dorsal view with a Cognisys stacking system on a horizontal plane. That is the camera is mounted on the Cognisys horizontally so I nee...
