Playing out with integration

Ok, so we were making some tests with the dummy weapon, trying to integrate the cg weapon with the live-action footage. We used a worst case scenario, recording in the basement with poor light conditions, so far so good.

Antonio made this test still render:

The best way to achieve a good integration was matching the same lighting conditions using a spherical high dynamic range image (HDRI). I got one of these mirrored ball on amazon, these are used as garden ornament, pretty useful though. This one is too small so it was hard to get a sharp image but in this case we don't need that extra level of detail for lighting and reflections.

I used a bracketed sequence of pictures with diferent exposures, merged to HDR in photoshop and warped to spherical panorama in HDRShop.
