    Failing to orient cameras

    Hello, I am completely failing to do a 3D construction using 3DF Zephyr. I generated about 120 photos by sitting in a rotating chair and fixing a camera, then taking about 40 shots as I rotated. I then repeated the process with the camera in a low position (looking up at me) and a high position (looking down on me. So, the cameras should be in 3 circles around my head (the subject). Nevertheless this is not at all happening as you can see from the result below:

    [img src="https://i.stack.imgur.com/lXFHi.jpg" alt="camera positioning" /]

    As you can see from the image all the cameras are clustered on a single axis, not arranged in a circle.

    How can fix this problem?

    The keymap generation was done with the High quality, Human Body settings. The pictures are high resolution jpegs taken with a Nikon D200 which the software correctly recognized and calibrated for.

    Hi Jsc,

    have you masked the images? It seems like Zephyr tried to reconstruct the background, that is fixed in this case. When using a 'turntable' setup (fixed camera and rotating object), masking is mandatory.
