Hi,I have studied this soft for several days and have 2 questions:

1、which keyword is used to set the focus of perspective model carema?
look_at?direction? or others?
2、Besides，when one focus of the carema is set,how can we ensure
that the objects of the image is clear under this focus?

I'm confused about this.Could anyone help me? Thanks!
