Depending on your scene, and the location of the camera, rotating the
camera can result in uterly unreasonable offsets, like accidently
diverging camera axis or excessive convergence.
It's usualy beter to translate the camera /after/ you set the look_at
point for images like paysages or points of interest a fair distance
from the camera.
If the point of interest is close to the camera, then, it may beter to
translate the camera, then, set the look_at point at the same location
for both views. This correspond to the natural converging of the eyes
when looking to something close.

Yes, the camera's horizontal field ov fiew in degrees.
dependent on how the image is to be viewed.
