    Initially the images were prepared to be viewed on VR devices. I have reduced their size and reversed their order (from L/R to R/L) so that they can be viewed directly, in "cross view" mode.

    I am not certain if movie clips can be up-loaded to this site.
    Here is a link to a movie clip I did yesterday. It is crossview.

    What technique do you use to get these macros in 3D?

    Depends on situation.
    - For static subjects I use the method with the lateral movement of the camera (cha-cha) on a dedicated device mounted on a tripod. In this way, the focus can be adjusted very precisely.(images 1, 3 and 4)
    - For video and subjects in motion that require a greater working distance, I use a system with two identical cameras, with identical long-focal lenses, mounted in a system with a beam-splitter (special mirror 50% Reflection/50% Transmission ). But the installation is large, heavy and difficult to handle.(image 2)
    - I also have a macro system with two lenses that projects the images on one half of the sensor each, but the stereoscopic base is fixed and the optical quality is below that offered by normal lenses.(the image attached to this post)

    Thanks for this. I only tried the "cha-cha method" so far. :-)

    I use several methods
    1. Cha-Cha for subjects which are not moving. This could be with normal lens or macro lens. I may use a tripod, or I do it free hand which is possible with practise.
    2. A variation on Cha-Cha is to hold the camera and move it sideways whilst taking rapid stills ( say 10 per second ). Then choose two of the images for making the stereo image.
    3. For moving subjects, I use two cameras.
    (A) two cameras side by side on a bar which is on a tripod. Care has to be taken to obey the 1 in 30 rule. That is for good 3d effect try and keep the subject 30 times or more than the distance between the lenses. To sync the two film clips ( when doing 3d movies ) I try and use a high frame rate of 60 or 120fps.
    (B) two cameras on a rig which has a beam splitter ( 50% transmission and 50% reflection ) I built this rig myself using mostly wood. This rig has an effective spacing between lenses of 5 to 15mm ( adjustable ). I use this for macro work.
    (C) two cameras on a rig which has a normal ( high quality ) mirror. This mirror is placed at 45 degrees to one of the camera's lenses. With this method I can get an effective lenses spacing of about 40mm - so it is good for subjects which are around 1 metre or more away.

    The cross-eyed viewing method swaps the left and right eye images so that they will be correctly seen cross-eyed, the left eye viewing the image on the right and vice versa.

    Yes!

    As did its proboscis (sp?).

    I hate pictures of insects. But there’s no denying the remarkable “3D” result of the techniques used.
