Here is a link to the 3d clip

The 3d close up of the Beetles are done with two camera on a rig. The rig was made by myself and has a half-mirror ( beam splitter ) in it. There are many problems with macro filming using two cameras. One is getting both cameras to be in focus on the same point in the scene. For example one camera might focus on the insects feet and the other camera on the insects head and with a small depth of focus which you get on macro , it can effect the overall 3d effect. Another is white balance should be the same on both cameras. Another is alignment between the two cameras - there needs to be a bit of toe-in otherwise when aligning the two clips in software some of the image is wasted at the sides. This means lost pixels and lower resolution on the final combined image. For example the two cameras might be 1280x720 pixels ( 120fps to allow slow motion and better alignment in timing which is necessary ). In software the two images are aligned and after that the useful remaining image may only be say 900x 530 pixels for good 3d alignment.
