[chimerax-users] Questions about focal length of camera in ChimeraX

[Elaine Meng]

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:

I hope this helps,
Elaine
