  • Use security camera specifications in VRayPhysicalCamera?

    Hello all,

    Is possible to use these camera specifications in the vray physical camera?
    Does anyone knows how to do it?



    Thanks in advance.

    yeah you should be able to do it.
    The security camera has quite a big FOV 90odd degrees so you might have to play with the film gate to get it to match

      First of all, thanks for your reply.

      Could you tell me how to do it? Where do i have to put all those values?
      Or i have to do it manually? like matching my scene to a frame from a film captured from that camera?

      Sorry any english mistake.

      Best Regards

        As far as I understand that, the H, V and D stats are the Horizontal, Vertical and Diagonal field of views in degrees. The lens on this model of camera is a zoom lens from 2.9mm-10mm.

        You need to create a max camera with the H FOV and note the camera angle, then create a vray camera and put in that figure.

        Now you need to work out the crop factor which is the ratio between a 35mm frame and the chip size of this camera. Somebody will have to come in here as I can't remember how to get this figure (but it should be easy enough as the specs give you the chip size), but this figure should go in the 'zoom factor' of the vraycamera.

        I think that's about it.

        <I think the crop factor (or zoom factor) is 43 (the diagonal measurement of a 35mm frame, in mm) divided by the diagonal measurement (in mm) of the chip>
