Hi Bin, Focal length may not have a meaning in ChimeraX, because you can't make an image "out of focus" ... i.e., it doesn't get blurry at any distance. There is only the angular field of view, eye separation, ... as explained in this page: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/camera.html> I hope this helps, Elaine ----- Elaine C.

Thanks very much for your software so that I can specify the camera position and then take a snapshot. However, I can't find the information on the focal length of the virtual camera.
I am using mono (default) – monoscopic with perspective (apparent size decreasing with distance from the viewer), and I didn't see any details about the camera intrinsics. Regards, Bin
