1. Open ...\Steam\SteamApps\common\Vampire The Masquerade - Bloodlines\Unofficial_Patch\cfg\autoexec.cfg in, for example, NotePad++ or basic NotePad.
2. After "snd_refdist "52" make space and put:

bind ''KP_PLUS'' ''+camin''
bind ''KP_MINUS'' ''+camout''
bind ''KP_UPARROW'' ''cam_yaw 180''
bind ''KP_PGUP'' ''cam_yaw 225''
bind ''KP_RIGHTARROW'' ''cam_yaw 270''
bind ''KP_PGDN'' ''cam_yaw 315''
bind ''KP_DOWNARROW'' ''cam_yaw 0''
bind ''KP_END'' ''cam_yaw 45''
bind ''KP_LEFTARROW'' ''cam_yaw 90''
bind ''KP_HOME'' ''cam_yaw 135''
bind ''KP_INS'' ''pause''
bind ''KP_DEL'' ''screenshot''

Done. Now you can rotate camera, zoom it, make screenshots when your character is looking at the camera via numpad.
