Hi all,

Was wondering if there is a way of adjusting the focal length of Camera 1 in the Carrara scene ?

I am asking this because when I load up M4, select his head, hit '0' on the keyboard (to zoom in on the selected object, i.e. his head) and zoom out a little bit --- the head looks distorted (similar to Poser before changing the focal length of the Face Camera to, say, 150).

Thanks and regards,
Andrew

 Hi mathman,

Long time no hassle!

This answer has two parts: 1) focal length vs. lens size, and 2) the shortcut. 

  1. Carrara let's you numerically enter a lens size which directly relates to focal length. However, it doesn't let you numerically set a focal length. So, if you don't want the fish-eye look, just like the real world, you'd pick a larger lens, stand further away and zoom in. You can do the same thing with Carrara by changing the lens to something like 200mm and moving the Camera.

  2. But "1" is the hard way if you're not animating the camera. The easy, fast way is to leave the default settings for Camera 1 and simply grab the handles on the production frame box (Edit > Show Production Frame) and drag it until it's tight on the subject matter. Then without moving the camera, you'll get an undistorted close-up render.
