Post subject:  Camera angles ?
I was wondering what are the best angles one could use for the camera rig ?

I was watching the video you guys have of the dancing man they seem to be separated by about 30 degrees or so, I was setting up my rig so 1 camera was at the front of the actor and the other at 90 degrees from the first camera something like this:

( it is looked from the Z plane ) birdseye view:


Code:
         0
        /|\   ================== CAM
        / \
          |
          |
          |
          |
         cam


however it seems you guys use inclination:
Code:

                       CAM
                    /
                  /
         0      /
        /|\   /
        / \ 
              \
                \
                  \
                    \
                      \cam




so what's the recommended setup for this ?

In general, you need 60-90 degrees between cameras.

I would recommend to start with 3-camera setup with 60-70 degrees between cameras. Make sure that your 3 cameras are not set up in one line. Set them in semi-circle. It helps setting cameras at different height (like one camera higher then other 2).

2-camera setup is only useful for simple motions. We used it in our 8-month-old demo just as experiment. I recommend 3- or 4-camera setups for complex motions.

So for a 3 camera setup you don't recommend setting up all the way around the actor? 120 degs apart. A semi circle is good enough?

Semi-circle should be good enough.

An illustration is embedded in iPi Studio. Open a 3-camera video and look at default camera positions.
