Shooting the image with those keywords... Hmm, do you mean that I need to 
put these two keywords inside the camera directive? To be honest, due the 
lack of experience and knowledge with these two keywords, i would just like 
to ask you to give an example where and how to use these two keywords in a 
scene. I think, that should help me.

Thanks, Jan.

Sven
