Hi Phil,
as far as I understood,, the 3D Technician needs all the lens and sensor Parameters to reproduce the same field of view in Computer. On top of that we have to shoot HDR shots with a mirrored silver ball. If it`s not a matter of the Crop Factor, what can I do to achieve everything a DP should look for in such a Situation (prodviding all data for CGI). As I already wrote, I`m pretty new to VFX Shooting. Any additional advise would be very helpful. Thank you.
