Hi, is it there a Shift camera for Daz Studio?

    You can straighten out an existing camera by adjusting the rotations.

    Use the Lens Shift parameters, as I recall.

    This is about adjusting the effective position of the backplate, so that if you hold the camera horizontal at ground level and point it at a tall building you get the building in the middle of the frame, rather than just getting the ground and the lower part of the building. If you tilt the camera without the shift then its vertical will converge. It's a technique much used in architectural photography.

    Thanks for the reply Richard and Kenshaw.

    Presicely this is for some buildings renders. 

    The shift parameter would avoid having to crop an image to get the verticals staighten. One can point the camera up without messing up the verticals.

    I tried the lens shift X and Y in the camera editor but nothing came out, Im I doing something wrong? Or are this parameters for another function?

    Create a camera, and zero its transforms - other than Z Translation of 120

    Create a cylinder 1m high, 10cm diameter, at the origin.

    If you are using Iray make sure that Draw Ground is Off in render Settings, and I used a square render.

    Render and your cylinder will occupy only the top half of the image, and its top will be missing.

    Select the camera and set its Lens Shift Y to -5.5

    If you render again th cylinder should be fairly centred (I roughly placed my elements so the given measurements don't match exactly, but should show the effect).

    Yeaah! Got it Richard! Right on. 

    The shift it does not appear in preview mode, which is kind of lame, but if I turn on the Iray interactive render I can see the changes, and it does the trick.

    Great thanks a lot Richard.
